Design and User Satisfaction of Interactive Maps for Visually Impaired People
Multimodal interactive maps are a solution for presenting spatial information to visually impaired people. In this paper, we present an interactive multimodal map prototype that is based on a tactile paper map, a multi-touch screen and audio output. We first describe the different steps for designing an interactive map: drawing and printing the tactile paper map, choice of multi-touch technology, interaction technologies and the software architecture. Then we describe the method used to assess user satisfaction. We provide data showing that an interactive map – although based on a unique, elementary, double tap interaction – has been met with a high level of user satisfaction. Interestingly, satisfaction is independent of a user’s age, previous visual experience or Braille experience. This prototype will be used as a platform to design advanced interactions for spatial learning.
