Obvious physical constraints

2010.07.29 - 02:07



Many countries utilize RFID cards at high way tollgates, ranging from free passes with which cars can simply drive through the gates, to transportation or credit cards. Replacing cash transactions alone can speed up the process of passing through the tollgate.



This tollgate in Seoul, on the way to Incheon airport, had 3 card scanners each accommodating the different height of the driver seat. Designers must have gone through several options before deciding on this solution: A stronger scanner? Material and manufacturing cost of the machine? Off-the-shelf components available on the market? Ergonomics of the driver reach on different vehicle types? Maintenance cost? Variations in the usage contexts where the scanner should be installed and used?





Cash is an incredible medium that has lived through centuries in human lives to facilitate exchange of values. Any attempts to replace cash were accompanied by the heavy investment in the infrastructure over a long period of time, such as transaction terminals that suit various contextual and business requirements. Similar to any communication technology where the real value is in exchanges among people, it could move very slowly till the minimal size of ‘majority’ starts to get equipped with the tool and people get convinced that there is a clear benefit for conversion.

This slow change, in turn, could also result in intermediate technology solution in order to accommodate the existing human processes. For instance this signature pad has become a very common tool at the checkout using credit cards in South Korea. This replaces a printed receipt for getting the customer’s signature for the shop to keep. The credit card payer signs on the pad and gets the final receipt with the signature captured on the pad printed on it, typically in low resolution. This allows the shop to keep the transaction record electronically, which simplifies the process of bookkeeping. Is this working better than ‘Chip & Pin’, requiring a 4-digit personal code with IC chip embedded on the card as is widespread in UK? Advantages and disadvantages are different between the two methods, but I guess that’s beside the point. South Koreans opted for a technology solution that produces an equivalent outcome to an existing process: a printed receipt with personal signature, while being able to record the data digitally at the same time.





The signature pads I have tried invariably made me write my signature distorted or cut due to the inadequate feedback and lack of personal calibration (I was not exactly given a practice run either), or simply I started with the wrong size for the given space. So most of the times, I get a receipt with my signature printed too small, too big, unrecognizable, or incomplete. Does this matter? In theory yes, but in practice no. People have embraced the ineffectiveness, the defect of the technology tool because it still allows them to comply with the existing rule and process to a degree.

In India, I sometimes have to hand over my credit card to my driver (yes, I have to rely on a driver to live in Bangalore) for transactions. First time I got the receipt with no signature, I asked him “Don’t I need to sign this?” His answer was clear and simple as he started the engine: “Anyone can sign.” A similar attitude, but a different behavioral solution from the South Korean example.

Will either of these solutions prevail in the future? I would say yes, until the evidences of failure becomes apparent to the majority. We are, after all, humans who embrace mistakes and learn from them. But still – can we really design for adoption, abuse, appropriation and degeneration? Is it a matter of trying, an attitude? This is an increasingly relevant topic for my work these days. If you are involved in designing an infrastructural service that will have to transcend time, space and a large body of population, the cost of ‘we will iterate the design after we deploy it and get the feedback’ can be huge, if not leading to the failure altogether. It becomes critical that the patch tests of contextual validation trigger a wide variety of scenarios to consider, for policy creation, changing the existing process (gradually), training personnels, and establishing the word-of-mouth concept propagation message – including the potential ‘myth’.





Bonus: The new equipment invested is a chance to add on other features. The highway tollgate receipt comes with advertisement and coupons; POS system with the signature pad often comes with a screen facing customers that play ad videos.

HIV prevention awareness signage in UP

A signage for warning the danger of HIV and promoting the use of condoms, found across in Uttar Pradesh.

Getting condoms however may not be an openly accepted behavior. In rural health centers, they try to distribute condoms for free, but people may not visit the center while others can see. One solution to the problem is to place the condom dispenser outside so that people can take them whenever they feel comfortable.

I wish smart bollywood stars could do more on sexual education in India, given their influence and what they are selling, even though the reality in India is still quite harsh.

Standby affordance

A change in the plan of the fieldwork trip – we decided to take the train from Delhi to Bareilly. My suitcase was obviously a wrong form of luggage in the jam-packed Delhi train station on Sunday. We could not even dare to find the platform through the wall of people. A ‘coolie’ was found and I knew it from the moment I saw him that he was our savier for the journey: He not only carried our bags in 40+ degree temperature, but also made space for us to move forward, and guided us to find the platform and the right compartment. I could barely keep up the pace with him to follow. Without him, I am sure our 30-min spare time till the departure would have been a futile struggle.

When we got near the train, it was even more difficult to move. There was a long queue of people waiting indefinitely to get into the 2nd class compartments. It was first-come, first-serve basis, so they had no idea whether they could possibly get in or not. When the train finally started to move my mind was racing through the indecisive emotion wave of relief, discomfort and pity – looking at the solid human line of those who were waiting patiently in standstill without the success of getting in.

What I found out later was that even for 1st class where passengers are given pre-assigned seats, if you are on waiting list, you have to wait at the station. Because there is no way for anyone or any online system to know which seats would actually be available in the train until the physical train arrives. The reserved seat passenger names are listed on a printout outside each compartment. The fact that you could make reservation online didn’t mean much unless you get the confirmed seats at the time of reservation. As there is no obligation to buy the ticket before the train leaves, people have the mentality of just booking the train first anyway. Cancellation fee is too small to make people cancel the reservation they no longer need. So everyone has to wait at the station if you want to travel. If the train gets late, the station officers would tell you ‘its coming in 5 minutes’. After hearing the ‘5 minutes’ answer for about 10 times and the actual waiting time of 2 hours, your romantic image associated with the train journey starts to diminish dramatically. ‘In 5 min’ in India is highly metaphorical. It is a lip service of the person who is in the position to answer you despite the uncertainty of the situation, or the lack of information source available to that person. Alternatively ‘In 5 min’ is an answer simply used by the person who has no sense of time or empathy to understand the urgency you are faced with. I often feel that I am silently mocked by those who watch me get frustrated with delays: “What’s the hurry? You can just watch the world goes by, like me.” I am learning to live with IST (Indian Standard Time) for my mental health.

What I also found out furthermore was that there is an exception to this reservation system. Our ‘luxury’ 1st class compartment had four full passengers to begin with. After a few stations, a family of 6 turned up, guided by a gunned guard in the train. According to the translation, the man heading the group told us in Hindi: “Make space for us”. He or any of his companions obviously did not say ‘sorry’ or ‘thank you’ for accommodating his family and himself, making the 4-person compartment a 10-person discomfort zone. All Indian passengers fell silent after they got on board. The compartment was only filled with two men’s loud voices of phone calls and conversations. When the baby of the family started to cry, the same guard came over, took the baby in his available arm that was not holding the gun and left.



Implications of dysfunctional infrastructure are multifold. The important question is whether the society and those who are in power both have shared motivations to improve it. Habits and everyday behaviors that people have become used to and take for granted are most difficult to change.

Drivers in India – at least for commercial vehicles – are rarely alone in the car. There is always a companion or more in some form near the driving seat.
