HUMAN COMPUTER INTERACTION(HCI)

Q2. The proposed “Cicret” bracelet incorporates a pico-projector and proximity sensors to allow
users to project displays onto their own skin and to employ gestures to interact with the device.
(video: http://cicret.com/wordpress/). The concept is illustrated in the mockup below:

A. From what you know about design (Dix et al.,) and wearable computing, what are some of
the issues that the designers could expect with this device?

B. Design a usability study for the Cicret device. Is predictive evaluation useful?

C. Are there gestures that are typical of capacitive screens that could fail on this type of
device? Explain how you might mitigate this if so. What new gestures could be implemented?
