IDA-exjobb: A design space analysis of user interfaces for a meal planning system for elderly

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
Background
==========

For people of old age, malnutrition is a surprisingly common problem. Such malnutrition comes from a lack of variation in food intake, among other things, and is a common cause of hospitalisation among the elderly.

A research project at the laboratory for intelligent information systems at the department of computer science (at LiTH), is developing a meal planning system targeted at this malnutrition problem. This system will provide the elderly user with a suggested meal plan for a specified time period. This meal plan will be optimised based on several criteria including cost, ingredients available to the user, meal preparation time, the user's food taste, dietal restrictions, variation of ingredients, etc. This exjobb is about investigating the space of possible user interfaces for such a system targeted at elderly users. The starting point will be the information currently known about older people and computer interaction (suitable references will be provided by the supervisor).

This exjobb is suitable for one or two students (e.g. from C, D, or IT programmes at LiTH) with an interest in human-computer interaction and user interface design. Experience in the Java programming language is a distinct advantage.

Task description
================

1. Survey the existing literature on older people and computer interaction.

2. Analyse the design space of user interfaces for the intended meal planning system, taking into account the characteristics of older people.

3. Construct prototypes (preferrably paper prototypes) of a few suitable user interface alternatives, and evaluate them.

4. Based on lessons learned from the prototype evaluation, construct a final user interface design, and implement it in Java.

5. Document the work in the exjobb report (written in English or Swedish).
