Navigating complex routes and finding objects of interest are challenging tasks for the visually impaired. The project NAVIG (Navigation Assisted by artificial VIsion and GNSS) is directed toward increasing personal autonomy via a virtual augmented reality system. The system integrates an adapted geographic information system with different classes of(More)
This paper focuses on the experience we have acquired by developping and using the Ivy software bus to design human-computer interactive prototypes for Air Traffic Control. We list its properties for designing and developing light and powerful HMIs. By presenting our experience, we hope it will foster the design and development of the future architectures(More)
Multimodal interactive maps are a solution for providing the blind with access to geographic information. Current projects use a tactile map set down on a monotouch display with additional sound output. In our current project we investigated the usage of multitouch displays for this purpose. In this paper, we outline our requirements concerning the(More)
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(More)
Orientation and mobility are tremendous problems for Blind people. Assistive technologies based on Global Positioning System (GPS) could provide them with a remarkable autonomy. Unfortunately, GPS accuracy, Geographical Information System (GIS) data and map-matching techniques are adapted to vehicle navigation only, and fail in assisting pedestrian(More)
This paper deals with research for the design of " sound fonts " and development of an evaluation methodology suitable for use with non visual presentation based on the speech modality or on multimodality (speech and tactile). The work hypothesis of the study presented here relies on the fact that both structure and typographic attributes increase the(More)
Participatory Design is a process for the design of interactive systems integrating the user in all design phases. However it is based on the assumption that users are in possess of their full physical capabilities, in particular the visual sense, and thus is for the most part not adapted for working with visually impaired people. In this article we present(More)
In this article, we propose a soft keyboard with interaction inspired by research on visualisation information. Our goal is to find a compromise between readability and usability on a whole character layout for an Ultra mobile PC. The proposed interactions allow to display all keys on a small screen while making pointing easier for the user by expanding any(More)
