video calls: intrusion potential

i read a short korean newspaper article today about sexual harassment through video calls. illustration below & the original article from kyunghyang.com.

sexual harrassment through video call

according to the article, the reported callers disabled the caller identification so the receiver could not judge who the call was from before deciding to take the video call. one of the victims captured the video call with a camera and reported to the police. the victims said that the received video calls showed either masturbating scenes or exposed genitals. another sexual harassment case was also reported on a man who repeatedly made video calls of sexual nature to his (ex)girlfriend. the article urges a solution to prevent harassment attempts through video calls as their impact on the victims can be more substantial than text based messages or voice calls. particularly, in these cases, police failed to identify the callers through the mobile phone operators because of the caller id protection, which did not seem to have been designed for cases like this. if you can read korean, the original article is found here.

i pick on this as it is a good example of abusing a useful tool: can there be a smart design solution that could prevent or reduces the impact of the abuse without compromising the regular, normal usage (including the phone, calls, and the caller id function itself)? or a solution that would discourage people from attempting so to begin with, like advertising the existence of the surveillance cameras? the intrusion potential does become higher as the bandwidth of information transmitted through each communication session increases as with the potential benefits. furthermore as mobile communication channels diversify, it is important that people can be still in full control: how do i want to be connected and disconnected? this question has so many facets that relevant answers may (have to) come from – device user interface design, communication infrastructural design, legal enforcement, transformation of social norms, personal lifestyles and preferences, competence in using the device. people have incredible ability to adapt to or reject changes and the trade-offs between the cost and the effect will be always assessed before it is fully integrated as a behavioral change.

perhaps my past project called ‘defined delivery‘ may be a slightly related example of a design work on the topic of increasing mobile communication modality and therefore the social sensibility. the zest of the concept was that text messages can be delivered to the recipient in the desirable / desired context as the sender intends to, as this is our natural communication behavior. for voice calls, it is not rare that we ask upfront to the recipient whether it is good time for a call, implying that the caller does not want to interrupt the recipient and/or the call needs to take place in certain contexts – be it the recipient’s physical state or attention level, or the noises from the environment. translating the same principle into text messaging context, we designed and built a new messaging prototype application on Nokia 7650s that enabled the sender to define the context in which the message should be delivered (in fact notified) to the recipient. the prototypes were tested with a group of high school students and the result of this work was presented at CHI 2005, and the presentation can be available upon request to jung at younghee dot com. the official conference paper can be downloaded here (but beware of the boring language if you are not familiar with CHI paper format).

without going further on speculating the specific design solutions to relieve the mishaps of the intrusion potentials of the video calls, i would like to jump onto a simple example on how japanese people came up with solutions against sexual harassments in crowded commuter trains. have you have been to one of those super crowded trains which designated personnel to push people into, wearing white gloves? all illustrations are from other websites – click on the image to go to the webpage where it is originally posted from.
beware of chikan

it is difficult to identify the owner of the hands in an extremely crowded, confined space. and even if you do, it is not easy to deal with the situation when most passengers are under time pressure without being able to move freely. one solution is to designate women-only metro cars during peak hours.

another is to raise the public awareness of the fact that being ‘chikan’ is a criminal act through posters and signs. photo below is from jan’s weblog.
chikan is crime

there are a number of personal mobile accessories designed to prevent ‘chikan’, like a pen-sized stun gun or an alarm buzzer.

the legal system has also developed to promote victims to report cases. but it seems that the side effect is also substantial as once accused, it is difficult for men to get away with it. read these humorous tips for men below about avoiding false accusations of being chikan, with the original article in japanese found here.

[ excerpt from mari’s diary ]
No.1 Don’t stand behind women. especially you should skip beautiful woman.
No.2 If she misunderstands and glares at you, never look away. You should glare at her back. There was a precedent case that the testimony “he looked away, so I was convinced he was the molester” was accepted in the court.
No.3 Unfortunately when you are misunderstood as a molester, you should never go to staff room in the train station with her, even though she insists. The law of criminal procedure permits the immediate arrest by a private individual. If you follow her, it means you are arrested by her and she can turn you in the police. To take the best chance of clearing yourself, you should leave the place after giving your contact address to her.
My friends say they try to read a book using both hands, or one hand in the bag and the other holding on a strap.

NYT: Can the Cellphone Help End Global Poverty?

i am in the middle of the mess for moving to london end of the month, but felt obliged to log this article here with a little bit of recollection of the past year’s work.

last year, we hosted a journalist, sara corbett in our fieldwork in accra, ghana. her experience with us introduced the backbone of her article featured in new york times magazine, told through our darling media embassador & my long-time colleague/ team mate/ tokyo office neighbor/ personal financial advisor, jan.

perhaps overly self-conscious at the fact that i work for a mobile phone manufacturer, i rarely use the word ‘cell phone’: especially when i have to refer to something that will be available in the future that will change using our natural ability in new yet relevant ways. be it a cell phone or not, it’s not really relevant – its about what kind of personal and social technology and services will be feasible and possible and easy to adopt.

are you fancying about becoming design researcher yourself? while i eagerly wait for a more formal opportunity to talk about our research in the future, here’s a quick & random recollection of my personal experience in our last year’s project, future urban, in four cities of chongqing (china), mumbai (india), rio (brazil) and accra (ghana).

chongqing was our pilot city for the project, so we spent more time in ad-hoc interviews, which means going out with a local translator to a part of the city and informally interacting with locals. chongqing is a very fast changing, industrial city. it is very common to see the site of demolition right next to the brand new buildings and commercial centers.

chongqing old/new

sometimes my local guide was reluctant to go to certain areas that i boldly, or blindly wanted to go as he was concerned about my safety. some houses we were eventually invited to were expected to be demolished in a few months – we could actually feel the vulnerable state of the house.

informal storage solutions

this is a kitchen in a temporary apartment for the demolition manager of a building. he and his wife lived in one apartment in a building that he was in charge of demolishing. being a nomad myself, i often think about minimizing my physical possessions by digitizing what could be in plastic or on paper. having their home in the country side, and moving from one building to another based on the job, they optimized their furniture by employing a much lighter alternative: plastic bags. it took curiosity and patience for us to encounter this couple, as the whole building site looked totally deserted and the demolition was half way through.

minimal living+dining

the same couple’s kitchen/dining table – the compact set of home electronics would probably fit into a suitcase. how minimal and mobile can our life be?

thanks to the project schedule, we arrived in mumbai in the middle of the monsoon season. it had taken all of us several visits to the medical clinic in tokyo for the due vaccination shots and emergency medicines.

walking on the (flooded sewage) water

can you imagine saying that dettol is your best friend? for those two weeks, i did feel very grateful at the invention of the antiseptic medicine. the regular flooding of the sewage water on the streets of dharavi however became one of the most memorable experiences in my entire trip. but it was heart-breaking to see the house getting flooded that belonged to one of potential research participants.

dharavi guesthouse

we stayed in a guesthouse right at the border of the dharavi community. while it was a small guesthouse, the prolific human service in india still made room service as an option. being able to enjoy the local breakfast is a blessing in the fieldwork. i don’t really have any staple food – not even coffee – so i thoroughly enjoy sampling all kinds of new food in the city or the community i visit.

dharavi guesthouse toilet

but of course liking the local food may have its high price. luckily i only spent one night of talking to the big whilte telephone during my stay, with company of earth worms and cockroaches casually making their ways around the bathroom floor.

early morning

one of my interviews was scheduled at 3:30am in the family’s home as that was when the interviewee started his day. finding the family’s house in the dark through the maze of small streets would not have been possible without our mobile phones. one of my two local translators fell asleep on the interviewee’s bed at the abnormal working hour while the interview was ongoing, and i panicked at the lack of her professionalism. but quickly realized that for the host family, she was a guest to be taken care of.

breakfast

i had my best indian food at our research participants’ homes. a pleasurable dilemma when you know that you won’t be able to go to toilet for at least half a day while you are on the job.

in favela jacarezinho in rio, we had a chance to discuss about our way of working most seriously & thoroughly.

favela jacarezinho football field

while the camera accessibility was an issue, we were lucky enough to have MC Serginho as our community guide, thanks to our local team. Mr. Serginho was truly proud of and in love with his community.

favela jacarezinho 'gato'

this is a picture of what’s called ‘gato’ in portugese. basically it is illegally drawn electricity cables. one of the challenges we often faced in our interviews was talking about illegal behaviors that are acknowledged and done widely or just by a few. it takes a great deal of trust for someone to be able to talk about it. sometimes i do wonder if how our questions would have worked in super-digital generations where the weight and the flow of information and hence the implications of the information disclosure is very different. i had my utmost interviewing skill tested in an interview with a professional sex worker lady in a public place in copacabana. a good reminder of the fact that the effect of who you are cannot be ignored in the fieldwork, as with many other things in our lives: i had the benefit of being a woman myself in the interview. likewise i didnt have a chance to interview any male participant myself in india.

after gone through electricity cuts, polluted air, flooding, security precautions, buduburam and accra in ghana were a comfortable breeze for the fieldwork. english being one of the spoken languages helped a lot as well, even though the common usage of multiple tribal languages complicated the research team planning.

buduburam toilet

i had a night of home-stay in buduburam camp. i stayed in an elegantly decorated lady’s room with the luxury of a toilet in the room. with water supply completely manual, i had gone through the experience of planning my water consumption so that i wouldn’t exhaust all the water supply just to flush the toilet.

buduburam - sachet buying, grains

many effective sales units defy the industrial packages in the community. grains are probably a natural one. more rare selling units included soaps and detergents, and empty bottles of different sizes for lamp oils.

oil selling units

a good sign of beginning to learn about the new culture is to grasp, or to wonder about the relative value of goods and services. and naturally this often constitutes a good part of our interview questions.

back to packing & pondering upon simplifying life & mobility prior to moving to another continent now. more later, hopefully.

surveillance techniques

Do you check your surroundings before you decide to quickly pick your nose, or adjust your underwear nowadays? We are increasingly aware of possible surveillance around us. Many authorities assume their legal right to place surveillance cameras, often as a measure to provide better security. In some countries, encouraging everyone’s participation to keep an eye on the suspicious people or objects may be necessary for the common good of the society. In some places, the signs of surveillance may be used as a measure to prevent people from misbehaving.

In Korea, a country technically still in truce, there’s a dedicated phone number, 111, to report spies (North Korean or industrial), terrorists, or international criminals. The rewards for reporting spies or spy ships are also clearly written in the commonly found posters: Approximately 65kEur for a spy, 1.5 times more for a spy ship. Having the dedicated phone number for turning spies in is a practice with a long history, which provides immediate ways to act for those who are willing and have access to voice calls.

An ad placed in buses in London encouraging people to be alert about the “suspicious”. Less direct than the Korean approach, but it at least stopped me to think about what would be appropriately suspicious enough to tell the bus staff or police.

In Helsinki, you may see stickers very visibly indicating the existence of surveillance cameras even though you don’t see the camera itself on taxis or in the airport. The camera icon without any written description implies that people would understand the meaning of the icon being the function of surveillance cameras.

The more typical signs possibly built with the intention of amplifying the effect of having the surveillance cameras are easily found in UK. The first sign is from London, second from Whistable.

Buildings with security companies behind them often display the company logos on the building. Perhaps the reputation of the security company among the petty criminals in the neighborhood is something we would need when selecting which company to turn to.

In buses or metro stations in Tokyo, this sign featuring big eyes are often found. It is issued by the Tokyo police department, read “We won’t let evil escape” – a message very indirect, but probably functions as a reassurance of the police’s presence.

tokyo police slogan

In addition to the formally established surveillance mechanisms, the emerging form of surveillance is enabled by the majority of individuals carrying recording and communication devices – as already discussed 3 years ago in South Korea over the ‘dog poop girl’ incident.

Leaving the debate on the good and the evil of the citizen journalism enabled by the proliferation of digital tools aside for now – I am wondering how people’s public behavior may be influenced by the implicit potential of people near you reporting your bad or good deeds. ‘Nearby’ people may be those who share the same physical space and time or communication channels like a chat session or a wifi hub with you at the same time. With digital devices’ increasing ability to capture contextual information such as location coordinates, reconstructing a coherent scene or a story with digital data collected by hundreds of people will become relatively easier as well.

Surprisingly a lot of people see mobile phone as a useful tool to capture evidences to prevent lies or fraud and to be used against future disputes in our recent work hosting a mobile phone design competition called Open Studio. On the other hand, the rejection for adoption may be well on the way as well. During the first trial of Lifeblog prototype in 2002, some people showed the fear of collecting the comprehensive personal mobile data including their whereabouts. It was the fear of giving up the protection of ambiguity, the plausible deniability when the usage of technology becomes widely known and adopted.

That leaves another interesting question: How would people drop out of, or at least minimize their digital traces and minimize contributing to create others’? We are probably not expecting stickers and badges showing “this person does NOT have cameras” or “this person will NOT use cameras”. One of the memorable Ubicomp conference talks was on the interesting concept of creating capture-resistant environment, preventing camera phones to take photos by overexposing photos attempted in the region covered by this technology. While I am sure there are certain types of places this technology would be very useful, I do have my doubts if there would ever be any technology successfully controlling people’s digital behaviors.

a confession on being a bubble in the internet of stuff

I am grateful for the opportunity to attend LIFT conference this year (thanks to organizers).
What left me thinking after the conference was the access to information, both in terms of breadth and speed. Within minutes, video recordings of talks became available online. The army of healthily pulsating Apple logos seen from the speaker’s stage was daunting, tappitytaptaptap, opinions and snippets of the talks being available and marked online as soon as they came to existence, in people’s ears and eyes. You are there, but at the same time you can potentially be anywhere.

200802_lift_01.jpg

LIFT was a big contrast to the academic conferences I am more used to, such as CHI, DIS, DUX, Ubicomp, and Mobile HCI. What you see in these conferences as audience is guaranteed to be old, usually at least 1 year. You as a shy speaker have little to worry about the presentation because your paper is your real glory. Having been published in these conferences can be considered that you earned a little stamp of quality for your work, at least in the eyes of your professors at your graduate school. Your paper might end up being read by less than a handful of people, but that’s ok – because you registered your name in the ACM digital library. Who knows, perhaps in 10 years there will be some other graduate students who will cite your publication? OK, I am overly negative now. Being a Korean and because of my personal upbringing, I am and will be perpetually chased by the favoritism to meritocracy – subsequently I still respect the academic institutions and their authorities.

But the world has changed. It’s about the influence. Information not found through google may have less value to humanity in general; outdated information goes through devaluation not necessarily because of the content but because of streams of other information we have to digest everyday.

Information is power. In many countries in Asia – knowledge and information has been used as a weapon to keep the general public out of power. The infrastructure will soon be there for any willing individuals to have access to the gigantic information pool created in the online universe. But there, we are defining a new type of meritocracy: Ability to search, ability to filter, ability to ignore, and ability to build and control online identity and reputation.

It is uplifting to hear the story of an undercover video clip made online by Humane Society, prompting USDA investigation which lead to recalling of millions of kilograms of beef; it is scary to watch the interview of a Korean celebrity against all the malignant gossips created around him, amplified and spread by the Internet. We are marching towards creating human societies in the subjective online universe – comprised of smaller bubbles of entities with their existence endowed by the attention and interests they manage to evoke; others wither into ether, or in memory and emotion of their creators.

I have no showmanship when it comes to speak in front of hundreds of pulsating Apple logos or unfamiliar people. I felt standing on a street on stage in front of LIFT audience and camera crews, a street that I cannot perceive how it is shaped, where it was, or how crowded it will be. I felt I was leaving a piece of me in a space that is not governed by the natural law of time. There was no protection of the wall that academic conferences provided, making the information not so accessible. Would I be able to get used to being on such spaces? It’s a question mark. After all – so long as I don’t google myself, those spaces minimizes their existence for me to a certain extent.

There is always a battle in preparing my talk to cut the material short to fit 20-min stage time I am usually given. 20 minutes is still way too short for me as I usually work with 1 hour or longer slots of time at my work place. But I do understand very well my value as a speaker is up to my ability to condense whatever material I got into the given time slot. After all, many professions depend on how well we tell the story, not on how well you do your job in your own world. My LIFT talk was mainly about the process of setting up a design competition in communities we went to for quick yet much focused ethnographic research, as a complementary method to understand the communities we knew almost nothing about. I didn’t go about its value and validity much, which probably disappointed some people but probably would have bored lots of people who do not work in the related professions if I did.

A few remarkable things for me about LIFT: I had the honor of being in the same session with the reverend Genevieve and Paul – which will be very memorable for a long time to come. I met a few brilliant minds that I never knew before, through the smartly arranged social breaks. I enjoyed experiencing the little Swiss moments, like the cheese fondue dinner, slices of cheese at lunch time, crisp air and Geneva’s efficiency. If you are around and available – come join next year! Or you can always watch videos online, without the extras.

Setting up my new travel laptop- could not resist trying the finger print software. Not only i failed in registering my fingerprint after dozens of trials, i started to doubt if i’ll ever use it at this horrid failure rate (not to mention that my finger prints may disappear after trying so many times!). I also imagine the very finger i register to the system may be cut, dirty, or for whatever reason becoming unavailable at the time critical moments. Beside, the only finger i managed to get at least one successful scan with was my right index finger. Quite many questions to the design of this particular scanner- why swipe when speed becomes another factor for very frequent failure?

Well, before i indulge, i should go back to my pressing work.

Office elevator buttons dont work with gloved hands. When i really felt lazy and when no one was around, i have used my chin to press the button.

The first time i experienced conductivity-sensitive buttons on the product was my panasonic walkman with a wireless remote. I was thrilled as it was magical, and the product was devoid of the ugly ‘hold’ slider. More importantly, it was nice because the buttons on the product was only secondary control, as i was using the remote control most of the time, which had mechanical buttons.
