Response to Thoughtful Interaction Design, 2 Examples

One example of a good user experience that I’ve found is the wayfinding system in NUH.

The designer of this system understands that visitors and patients have other concerns on their minds, such as handling the stress or pain that the symptoms are giving them. They might not have good vision to see the signage, or tilt their head high enough to read them. The thoughtful designer chose to put color coded lines, orange being the main building for example, putting it around eye level so it can be easily seen.

NUH staff such as doctors also benefit from this, being able to easily identify the correct way to any department even under stress or other preoccupations. Color coding the lines, and also showing the direction arrow before showing the destinations the arrows point to also respect the left-right and top-down conventions of readers, giving users a simple and consistent way of getting directions in an admittedly confusing complex of buildings.

While it is not a perfect solution to the problem, it is a good example of an accessible wayfinding system given the context of its usage. A possible addition can include braille letters on the handrail below it, allowing blind users to get directions too.


Another good user experience is the Grab mobile app. The company’s responsible designers help bridge the gap between the fantasy of an accessible and transparent car sharing service while also acknowledging the existing system of flagging a cab beside the road. Unlike Uber, Grab allows existing taxi drivers to use their service to find customers, letting them also bypass many government restrictions of fetching customers in no stopping zones. The app also transparently shows you the cost of each type of ride, and also lets you have a cheaper ride by sharing one.

The app also increases trust between driver and passengers by showing the driver’s profile before you even take the ride, even letting you know what car the driver is using. And after the ride, both driver and passenger can rate each other, giving the both control of their experience. This is different from traditional taxi flagging, which makes both parties anonymous to each other, making the situation more tense and anxious of shady behavior. It is a good example of responsible design, letting technology facilitate good behavior.
