Combining Sensorial Modalities in Haptic Navigation Tasks for Blind People
نویسندگان
چکیده
Recent development of haptic technology has made possible the physical interaction with virtual environments. The combination of sight, hearing and touch senses provides these virtual environments with enhanced realism perception and interactivity to simulate multiple real world tasks. Furthermore, the addition of the sense of touch can help in the design of specific virtual tasks for people with visual impairment. This paper analyses the advantages and drawbacks of combining tactile and sound stimuli to render virtual environments for blind people. Specifically, it studies the combination of both senses to provide navigation-related information in virtual tasks. A user study has been carried out among several subjects in order to discuss this issue. Results state that a combination of both senses provides better performance in navigation tasks than with only haptic feedback.

Mental mapping of spaces, and of the possible paths for navigating these spaces, is essential for the development of efficient Orientation and Mobility (O&M) skills. Most of the information required for this mental mapping is gathered through the visual channel. People who are blind lack this information, and in consequence they are required to use compensatory sensorial channels and alternativ...

متن کاملRobot-assisted shopping for the blind: issues in spatial cognition and product selection
Research on spatial cognition and blind navigation suggests that a device aimed at helping blind people to shop independently should provide the shopper with effective interfaces to the locomotor and haptic spaces of the supermarket. In this article, we argue that robots can act as effective interfaces to haptic and locomotor spaces in modern supermarkets. We also present the design and evaluat...
