Usability of technical equipment is pre-requisite for the successful introduction of users with intellectual disabilities on the labour market. In this project, an iterative user-oriented product development process was applied in order to develop a new user interface for a cash register to be used in e.g. cafes, restaurants, and hotels. The results show that general principles for usability (e.g. consistency, feedback, etc.) could be applied. However, some design elements proved particularly important to consider especially to achieve an agreement between the user's physical activity and the occurrences on displays / screens. The project shows that users with intellectual disabilities can participate in and contribute to a development project. However, special care has to be taken in designing e.g. problem inventories and usability evaluations.
