Exercise sheet 2
Groups of 2: For groups that have only 2 members, for some tasks a reduced amount of work is indicated with Groups of 2: as an identifier. This does not apply for groups that have three members.
Exercise 1 - Eye Tracking (6 points + 2 Bonus points)
Instead of using pointing devices, such as a mouse on a computer, one interact with virtual items by looking at them.
3. Consider a scenario where users only has their eyes for interacting (e.g., quadriplegia).
4. BONUS: Pointing and gesturing with ones eyes is very difficult to perform, and identifying where on the screen the eyes are pointing at is technologically hard to do.
Exercise 2 - Interface Types (8 points + 4 bonus points)
You need to know how Pac-Man works for this exercise. If you do not know the game,your first task is to play one of the many versions that can be found in the internet (e.g. https://www.webpacman.com/). Now consider the pros and cons of playing the same game using different interfaces. Consider a speechbased interface, a touch-based interface, a tangible interface and a virtual-reality and/or augmented reality interface (e.g. head-worn display).
For each interface type SUBMIT a description of how the game might be redesigned and
BONUS: Imagine up to two other post-wimp interfaces. For each additional interface
Exercise 3 - Weekly pill case interface (12 points)
Figure 1 shows an example for a weekly pill case.
Imagine that the case is interactive, and that it can detect a) if a lid is open or closed and b) how many pills are in a container. Imagine that the images on top of the containers are interactive and can display
any information you wish. Additionally, if you want, you could also imagine that the device is touch sensitive. Also, assume the case is connected to the internet or a smartphone via WiFi or Bluetooth.
Please make sure to scan/photograph your sketches in sufficiently high quality so that everything (especially text) is readable!
