Money Handling Training - Applications for Persons with Down Syndrome

Paying for goods and services is a fundamental activity of daily living. Persons with Down Syndrome face these situations as a challenge. Through the usage of assistive technologies, the project Poseidon aims to enable persons with Down Syndrome to be more independent. In this paper we describe a training application for handling money. The novelty is the concept of extending the screen of an application to a palpable table, which serves as novel interaction device. Furthermore, we design the user interface highly personalizable in order to cover a large range of learning profiles of persons with Down Syndrome.
