UCD Charrette

A first look into Human Centered Designed and Engineering

Generated Ideas on the Potential Users


Charrette is designing in a fast and intense environment and our assignment is to design an in-car screen in less than 2 hours. Our assigned user was the group of people that are easily distracted.


We summarized the distraction that our user might have into two kinds: first, the kind of distraction that will distract the user and led to danger, such as the in-car screen itself; second, the harmless distraction, such as changing destination while driving. We decided to prevent the first kind of harm causing distraction and guide the user when the harmless distraction appear. To limit the chance that the easily distracted user distracted by the screen, we added a vocal control to the in-car screen and put buttons to activate the voice control on the steering wheel. And when the user got distracted by another destination, our navigation will set a new route allowing the user to go to two location in the least amount of time.

Project Structure (Left) & Project Scenario (Right)


Since Charrette is a fast design process, there are ideas that we want to go more detailed on. We only discussed how our product works for the easily distracted user specifically on the navigation system. However, for an in-car screen, navigation should not be the only purpose. We wanted to add a flip screen on the steering wheel that the user can flip up to higher the car temperature and flip down to lower the temperature. Moreover, our design is helpful in easing the user by adding buttons on the steering wheel. However, we still have not counted in the possibility that the buttons might cause the user trouble when the user accidentally pressed the buttons while turning the steering wheel. In the future activity, to develop our product we will have to extend our thoughts on the real user experience and consider the possibilities that might occur.


This is my step in the world of Human Centered Design and I enjoyed the process of brainstorming with my team. At the start, I couldn’t keep up with the past pace in Charrette and I was having trouble with getting ideas out. But during my time in the Charrette process, I caught up with the process and I was generating ideas using my knowledge of the true world as well as imagination. After the Charrette, I think the spirit in the process is to let the ideas come out, no matter how crazy it might seem.


Charrette is a great technique for generating ideas at the start of the designing process. It is extremely helpful when there just a general idea of the product, Charrette at this point will help the designers letting go all the ideas, no matter achievable in real life technology or not. However, Charrette will not be a great approach when doing project required detailed design rather than a design outline. For example, when the project is to design a local market shopping app, charrette could be used to generate ideas about the app, such as location guiding, open hour alert. However, if the project is to design a part of the app to check product availability in surrounded stores, with the purpose so clear, charrette will not be a great tool since the project requires more detail and charrette cannot go deep into details.
