Vibrotactile Exploration of Indoor Objects

چکیده
This paper describes our study about how to make use of a tactile belt with 8 vibrators to present rich spatial information for blind and visually impaired people while exploring indoor environments. In order to conduct a Wizard-of-Oz evaluation with 12 sighted subjects, a tablet based application has been developed for setting indoor scenarios and exploration interaction. Two sets of tactile patterns for presentation of distance, direction and type of objects, have been evaluated based on one single actuator and multiple actuators, respectively. The results indicated that the subjects can acquire the rich object information through both of the two sets, and they were more sensitive on the vibration position than the vibration intensity.

A Device and Method for Multimodal Haptic Rendering of Volumetric Stiffness
Vibrotactile signals are produced during haptic exploration of compressible objects through a variety of contact and bulk mechanical processes. Prior studies have found that vibrotactile feedback can influence stiffness perception, but the reason for this is unknown. Here, we investigated the role of vibration in stiffness perception during object squeezing. We propose a physically motivated ex...
متن کاملA Cost-effective Indoor Vibrotactile Navigation System for the Blind
This paper describes the development of an indoor vibrotactile navigation system for the visually impaired people. We aimed at realizing a wearable, low-cost, and effective system able to help blind users in unknown indoor environments that they might visit occasionally, such as hospitals, airports, museums, etc. The designed system implements a Bluetooth (BT) localization service, and provides...

Knowing where north is provides a navigator with invaluable information for learning and recalling a space, particularly in places with limited navigational cues, like complex indoor environments. Although north is effectively used by orienteers, pilots, and military personnel, very little is known about whether nonexpert populations can or will use north to create an accurate representation of...

In this paper, we present a set of serious games with vibrotactile feedback developed for upper extremity motor function rehabilitation. These games are part of a framework called SIERRA that stands for Post-Stroke Interactive and Entertaining Rehabilitation with ReActive objects. The framework uses Augmented Reality technology to provide natural exercise environment and motivating virtual obje...
متن کاملUsing Vibrotactile Cues for Virtual Contact and Data Display in Tandem
In this paper, we present a treatment of the issues that must be addressed in using vibrotactile cues for multiple purposes within a single simulation system. Similar to the problem of overloading the visual channel in typical graphical user interfaces, care must be taken to keep the added cognitive load devoted to the vibrotactile channel of the user to a minimum. Vibrotactile cues are typical...
