Auditory navigation in hyperspace : Design and evaluation of a non-visual hypermedia system for blind users
Morley, S.; Petrie, H.; O'Neill, A.-M.; McNally, P. (1999)This paper presents the design and evaluation of a hypermedia system for blind users, making use of a non-visual interface, non-speech sounds, three input devices, and a 37 node hypermedia module. The important components ... -
Automated interpretation and accessible presentation of technical diagrams for blind people
Horstmann, M.; Lorenz, M.; Watkowski, A.; Ioannidis, G.; Herzog, O.; King, A.; Evans, D.G.; Hagen, C.; Schlieder, C.; Burn, Anne-Marie; King, N.; Petrie, H.; Dijkstra, S.; Crombie, D. (2004-12-01)The EU-supported TeDUB (Technical Drawings Understanding for the Blind) project is developing a software system that aims to make technical diagrams accessible to blind and visually impaired people. It consists of two ... -
Haptic virtual environments for blind people : exploratory experiments with two devices
Jansson, G.; Colwell, C.; Petrie, H.; Kornbrot, D.; Fanger, J.; Konig, H.L. (1999) -
Haptic virtual reality for blind computer users
Colwell, C.; Petrie, H.; Kornbrot, D.; Hardwick, A.; Fumer, S. (ACM Press, 1998)This paper describes a series of studies involving a haptic device which can display virtual textures and 3-D objects. The device has potential for simulating real world objects and assisting in the navigation of virtual ... -
Initial evaluations of a robot mobility aid for frail and elderly visually impaired persons
O'Neill, A. M.; Petrie, H.; Gallagher, B.; Hunter, H.; Lacey, G.; Katevas, N. (IOS Press, 1999)The Personal Adaptive Mobility Aid (PAM-AID) is an intelligent, indoor mobility aid for frail and elderly visually impaired persons which will provide both physical and navigational support For walking. The objective is ... -
The perception of texture, object size and angularity by touch in virtual environments with two haptic devices
Penn, P.; Petrie, H.; Colwell, C.; Kornbrot, D.; Furner, S.; Hardwick, A. (University of Glasgow, 2000)The incorporation of the sense of touch (haptic sense) into virtual reality (VR) has considerable potential to enhance the realism of virtual environments and make VR accessible to blind people. This paper summarises a ... -
Roughness perception in haptic virtual reality for sighted and blind people
Kornbrot, D.; Penn, P.; Petrie, H.; Furner, S.; Hardwick, A. (2007)Psychophysical functions for perceived roughness, relating ln (magnitude estimate of roughness) to ln (groove width), were obtained for blind and sighted participants in virtual reality using the PHANToM force feedback ... -
Use of a haptic device by blind and sighted people : perception of virtual textures and objects
Colwell, C.; Petrie, H.; Kornbrot, D.; Hardwick, A.; Furner, S. (IOS Press, 1998)This paper describes a series of studies involving a haptic device which can display virtual textures and 3-D objects. The device has potential for simulating real world objects and assisting in the navigation of virtual ...
