Car Multimedia System design
In this studio Class, we were asked to design a car multimedia system (Control panel) for special needs of the driver. Our driver is an elder with impaired vision, and we have to analysis certain issues which the driver may encounter. The first problem we considered is while driving at a low nature light environment, the driver may have difficulties seeing the roadway and traffics, thus increasing the possibility of rear-end collision and drive out-of-the road. In order to solve this problem, we designed a build-in driving assistant. As we considered the vision problem may also have negative impact while the driver trying to look at the control panel, we think it is better if the driving assistant is controllable via voice command.
The assistant is designed that it can detect the outside visibility, and when the visibility lows down to certain degree, it will automatically pop up a warning on the main screen and ask the driver if he needs to turn on the assistant. We make it to be active instead of passive because if the driver wants to open the assistant by touching the screen, it will distract him from driving which may cause accidents. After the driver choose to turn the assistant on, it will give him several options, for example, turn on the side-lights, limit the speed, auto-adjust car’s position to maintain it on the right track etc. and all of which can be set up by speaking to the assistant.
We used the voice instead of traditional bottom and touching process throughout the program, because the driver may also have problem reading the options on the screen which make him put more concentration on the screen instead of the road.
During the process, the step by step designing technique helped a lot. We start from getting a specific group of users(with special needs), then creating scenarios and laying out the interaction flow to sketch out the user interface screen. By targeting single objective once upon a time, I experience no problem ideating. In my perspective, this technique will be really useful while I developing any user interface related project in the future, also switching group members from one to another keeps us being innovative.
