Week 4 - Class Exercise

1. Redesign a functional element of a car dashboard

There are many components that are relevant to driving behaviour such as GPS system, buttons on the steering wheel and also voice user interfaces. Here is an example that descirbes one of the interactions. I would design a car that has a function of recognizing a driver's voice commands. If the driver wants to turn down the music, he could just say 'turn down the music'and the music would be automatically turned down. In this situation, the driver does not need to turn down the volume by hands while he is driving. This could also be implemented into the GPS system so that the driver does not need to type the address.

To test this interaction, I would make a few different commands such as calling someone by saying 'call Lucy Chen' to test its recognition.

2. Design and describe a horizontal, a vertical and a diagonal prototype for the alarm clock application

Horizontal Prototype

The user goes to the first interface that shows the overall information of each alarm. Then the user presses edit button and chooses Alarm 1 and it goes to the second interface. The second interface shows the detail of the Alarm 1. The user could change the time and set different tones for each alarm. The third interface is provided for the user to choose the alarm that wants to be daisy chained.The last interface is for the user to snooze by shaking the phone or slide to dismiss.

Vertical Prototype

Only testing the last interface of shaking to snooze and the function of sliding to dismiss the alarm.

Diagonal Prototype

A user wants to add an alarm that has a different tone with other alarms. He firstly goes to the first interface and presses the add button and then sets the time and presses the sound button to change the sound he wants.
