Spec. Requirements / Design Questionnaire - Christos and Joseph

Define Objectives:

1. To identify the problems encountered by the elderly while grocery shopping.

2. To assess the familiarity with various technologies

This will be useful in designing the E-Trolley because it will allow for the development of an intuitive interface similar to what the user is already familiar with

3. To define measures of improvement

It is important to have a means of assessing the success of the product. These questions intend to provide a way to measure that success by empirically and qualitatively measuring the improvements after the system is implemented.

4. To identify age bias disabilities.

There are some disabilities that are more frequent among the elderly. This will show which disabilities are prevalent and to what extent the target population is effected by it.

Things to bear in mind when writing the questionnaire:

1. Target the vocabulary for the elderly

Avoid using sophisticated or technological terminology as the elderly may be unfamiliar.

2. Avoid asking about future intentions

Assume the users don’t know about the e-trolley
