Full title

Perception enhancement for visually impaired people. A user-centered approach towards a fleximodal user interaction framework.

Introduction

Most existing interaction frameworks heavily depend on vision. Personal Radar is a user-centred approach towards a fleximodal user interaction framework useable for high- low- and no vision. The fleximodality is achieved by the ability of the framework to recognize and use the different modalities an output-device supports and by the flexible use controlled by the user.

Personal Radar is a real world use case which proofs the usability of the fleximodal framework.

Personal Radar is a user-centered design serving the community of visually impaired people in order to enhance their perception of local surroundings.
