displaced/fabricated nature

Living close to the nature is a privilege in many parts of the world. It is more so as cities become increasingly densely populated and expand. I grew up in a very human-constructed environment of South Korea’s former industrial hub, Busan, South Korea. Naturally, facing or getting too intimate with the real nature has always been a special, rare occasion to me. On the other hand I am very much familiar with the idea of miniaturized, sanitized, fake nature in the industrialized, completely made-up environment, simulating and sampling the idea of nature rather than providing the real experience of it [think a fake snow field in a department store window decoration rather than the deceivingly real artificial beach in Odaiba, Tokyo, Japan]. In doing so, we often mimic parts of the nature that takes minimal effort to maintain and is pleasing to our senses without unpleasant consequences.

In Seoul’s smaller city airport, Gimpo, there’s a airy lounge area that looks like a garden. Perhaps it is the obvious contradiction that makes it more charming, or acceptable, depending on where you are coming from. As a city child I didn’t even notice the ubiquity of mimicked nature until I came back to Korea after living in other countries. They are sometimes cute, but more often than not, can be repulsive, cheap, and horrifying. Like most animal cages in the zoo are simply sad to look at.

As depicted by numerous well-known science fictions, we will soon see the day when it is no longer interior decorator’s musings to create the artificial parts of the nature, as they may be required for the purpose of making people familiarized with the concept.

As a side story – in a Japanese manga series called ‘Five Star Stories’, the humanoid girls ‘Fatima’ who are specifically created for controlling the war robots are described. Their skin can only accommodate clothes made of real cotton, which in itself is an extreme luxury at the time. I was reminded of the story when I was shopping in India looking for a traditional cotton lungi in a local neighborhood: I tried almost 10 shops, and none of them had a single lungi made of pure cotton as it was too expensive.

credibility, at a glance?

how long do you give to form your perception and opinion upon encountering something you are not familiar with? how easy do you think you are influenced by the first impression when you make a decision to try a new service? what cues do you rely on to make your preliminary judgment on the assumed quality of the product or service?

this gentleman was standing on the street of stockholm holding a sign for an asian restaurant. it reminds me of the joke among my finnish colleagues about having me standing behind the ‘oriental wok’ section of our office canteen in helsinki to make it look more credible.

when does it become important for the service provider to enforce the positive association in promoting their offering? the waxing/tanning/nail salon sign is obviously held by a guy who look like he would never want such a service in oxford street, london. but the sign is held high up to make it visible in the distance even when the street is bustling with people, which may screen him from being seen.

sometimes the association may not have any logical alignment with a specific feature of the service being promoted. above is a poster for the local government election campaign in tokyo earlier this year. this candidate’s slogan holding a baby is “policy driven by residents”.

as a side thought:
any relationship between keroro and the ladies in tokyo anime fair 2008? i always wondered about the effect of having beautiful people around the product. it certainly seemed to attract more human photographers for keroro in this occasion.

gradual dissemination: the usefulness of touch

going through some of my old photos, i noticed how SUICA system, initially rolled out as a public transportation card replacing paper tickets using nfc (near field communication) technology has been gradually introduced in japan.

the copy on the ad above is translated something in the line of “fun transformation of your mobile phone” (photo taken in april 2008).

around march 2006 when this picture was taken, i saw lots of advertisements and posters featuring this penguin character representing suica. all focused on the concept of how suica can be used to pay for the tickets, make small payments at shops instead of cash, and touch interface. for instance, this little penguin character would appear in the tv commercials accompanying a lady traveling alone passing through ticket gates with her, and drinking beer with her at a bar. it was going everywhere with the owner. the penguin also enjoyed the stardom through lots of character goods produced around it – flush toys, key chains, hats, whatever you can imagine.

suica is one of the brand names in japan that does more or less the same thing or using the same technology (like UK’s Oyster card)- which is essentially a cash top-up card. with japan rail behind it, suica had the power to educate the mass about the new interaction method as the benefits were quite clear: no need for queuing to get tickets, less hassle in passing through the crowded ticket gates, fewer reasons to carry coins. the clear benefit primarily as transportation tickets supported the mass adoption as well – though we are still talking about several years. the maturity of adoption brought a few variants as well: registration is now possible so that you can get your money back even though the card is lost; you can link it to your credit card so that it can be automatically charged once the balance goes below a certain point; commuter-pass registration is possible, as most japanese employers reimburse the commuting transportation cost based on the price of the monthly pass.

of course suica and its sister systems have become available on mobile phone for some time (under the name ‘mobile suica’). it seems about 60% of mobile phones in the market supports the function already. my tokyo colleague, Fumiko Ichikawa has a brief report on the current state of adoption in her blog. what is pleasing to observe is the gradual expansion of its use for other purposes than micro cash payments.

ana (all nippon airways) supports several methods for check-in. obviously mobile phone enabled with nfc like mobile suica is one of them.

suipo (suica poster) is launched last summer – it is an advertising platform using mobile suica as interface. people can touch the indicated spot on the advertisement to get the ad on the mobile. or you can use the normal suica card to get the 2-d bar code displayed, a technology that has been around longer in the market. if the boss canned coffee ad does not tempt you as a smart usage of nfc, you can also read about navita, the public maps using the same information distribution system as suipo. as with 2-d bar code, i am not sure how widely this is used at the moment.

from penguins to mobile micro payment to touch-based information distribution: it is a nice example of how a new technology is disseminated in incremental steps, which was a long journey.

i had a chance to probe how chinese people think about touch or near-touch interface a couple of weeks ago. while the metro ticket system in shanghai is same as oyster or suica, most people could not think of any other use of a similar system beyond that. on the other hand, their understanding of bluetooth wireless technology seemed to confuse many people about possibilities and benefits of near field interaction. a remote indication to think about the adoption curve and mass-market education of new technology – with or without a cute penguin’s involvement.

stimulus

what types of stimulus allow for maximum imagination of viewers’? and when does the maximum imagination become just too much to make any sense?

it is certainly an important question in designing products for which people’s opinions matter but the present lifestyle and environment does not provide sufficient experiential references to the subject. as for the experience of a researcher/designer, this phase is the most tricky part because it is all about a game of stimulus-interpretation-linkage process, for the researchers, the facilitator, and people participating in the research as opinion givers. personally this phase can be also less fun compared to the exploration phase because of the pressure of making decisions and conclusions. no pain, no gain.

spent last week in these rooms, first time to be back since 2004. it was most refreshing to see once again how vulnerable this method is to numerous factors – the stimulus material, facilitator’s cultural/domain knowledge and ability to improvise, tone of the voice, translation, recruitment, group dynamics, and whatnot.

leaving the packed lunch, caffeine overdose, lack of natural light, and midnight dinners behind, happily landed in singapore for a couple of days.

mobile call manners

being in a country where i am sufficiently fluent with the local language, i get to overhear conversations regardless of my intention. my everyday 30-min bus ride in london always bring such an opportunity: unfortunately it is not possible to drop out of it. some people do force others to get to know bits of their daily life details whether they want it or not. the benefit of anonymity in a big city? perhaps. i wonder how they perceive privacy in the internet.

one useful tactic to talk on the phone in public is to use your free hand to cover your mouth and possibly the microphone on the mobile phone. benefits are clear for those who consider them as benefits:

– reducing the noise from your surroundings thus more pleasant for your calling partner and clearer hearing for you
– preventing others from overhearing your conversation

it is quite common to spot people doing this in japan and south korea but less as you move to west from there. one speculation is that certain cultures enforce the notion of desirable behaviors more clearly than others.

visual examples

as we all know – some messages are delivered much more efficiently by the accompanying visual examples, though they may not be an exhaustive set.

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.
women only metro car

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.
alarm pin

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.

location based information kit

upon entering a park in shanghai, there was a signboard with a compact set of information for park visitors. on the top, there’s a picture and a phone number of the person to contact should anything happen in the park. below, highest/lowest temperature of the day & other relevant phone numbers are listed. its a nice gesture but at the same time it is difficult to imagine how this set of information can be useful for park visitors in practice. it would take a lot of forward-thinking for anyone to predict the usefulness of these numbers & save them for future use upon seeing this information.

many location-based mobile services are subjected to play around the similar threshold of adoption, from service discovery to engagement to actual usage. often it is also about how to transform the linearity to an encompassing, opportunistic space: the physical sign board which broadcasts information at a set node vs. an information broadcast available in a larger area such as a park.

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.

car + mobile phone number

putting owner’s mobile number printed on the front window seems to be on its way to become a norm for car owners in korea. and often its not a scribbled note anymore. the parking convention in korean cities does require leaving the contact information on the car, as people may have no alternative in resting your car without blocking other cars’ exit route, for instance.

how private is your mobile phone number? what combination of contexts and other personal information makes it unacceptable to give the number out?
