The blog was set up as part of the requirements of HCI II and HCI II (Extended) in which a new product had to been designed using the User-Centered Design process.
After our brainstorming session where the members of our group came up with some really good ideas, we decided to design an eTrolley which will help people aged >60 do their shopping.
The next step was to create our personas who would help us identify some of the problems of the elderly people and to also take part in the testing and evaluation phase.
We started gathering the requirements for the eTrolley by giving out questionnaires to our personas, in order to learn more about their lifestyle and the way the carry out their shopping. An experiment was also taken place to find out the time needed to shop some random products from a local store using nothing but a trolley. Another member of the group observed how the elderly people shop and noted down some potential functionalities of the eTrolley that would help to reduce effort and shopping time.
We then came up we some creative designs of the hardware and different screens of the system. Some discussions took place between the group members to identify weaknesses or improvements in our designs before beginning to create the prototyping phase. During each step of the cycle, each prototype was tested by our personas who completed a questionnaire. This provided us with some feedback to help us assess our design and improve it where possible.
Finally, out last prototype was evaluated using two well-known evaluation methods:
a) Heuristic evaluation makes use of several evaluators critique a system independently to come up with potential usability problems.
b) Cognitive Walkthrough
