Assignment 3

The Complete Alpha Cognitive Walkthrough document can be found Here. It includes: Cover Form, Feedback Form, Problem Report Form


1) A description of the prototype of the system:
During our presentation in week 7 we hope to have some sort of physical prototype (might even be as low fidelity as David's model) that will have the interface embedded into it. The goal of it is to test the physical interactions that the users will have with the system. The prototype will have wire exposed to allow the user to hook their iPod up to the system and will allow the user to use the interface found on our interface slide of our final presentation last semester. We've designed it in a way that the buttons are layed out in the same order as many of the VCR's, Sound Systems and MP3 players have in order to offer enough affordance.


2) A description of the task the user is to perform on the system:
The user will have to successfully hook their iPod up to the centerpiece and play their songs by using the interface embedded into the device and then adjust the volume of it.

3) Complete list of actions:
- Ensure the centerpiece is plugged in and that your iPod is not locked.
- Take your iPod and connect it to the connector on the centerpiece.
- Locate the play button/glyph and press it.
- Locate the volume slider on the centerpiece and adjust the volume.

4) Indication of who the users are and what kind of experience and knowledge the evaluators can assume about them:
The users have a classy nature about them, we can assume that they've had experience in using an mp3 player / vcr / stereo system beforehand.
