During the design, it is important to evaluate user experience of representative users in many human product interactions. But, some cases, difficult or even impossible recruit because they have disabilities that do not allow them take part such investigations. Thus, alternative populations are widely studied. The most common way replace real blind people use sighted but blindfolded when studyi...

This paper introduces a shared Internet talking browser for the visually impaired called Talk & Browse (T&Browse) that allows a group of blind users to access Internet content and view the same HTML documents at the same time. Within the browsing session, the system allows two types of users: a sighted person (session supervisor) and blind users (session guided users). When the supervisor brows...

In the words of Gary Doern, Ph.D., a colleague, collaborator, and friend, “Few people have made more significant and lasting contributions to the field of clinical microbiology than has Jim Jorgensen, not only as a dedicated practitioner but also as an extremely productive researcher, an uncommonly effective educator, a broad reaching author, and a lifelong advocate for the discipline.” Such se...

We report three experiments on visual mental imagery in deductive reasoning. Reasoning performance of sighted participants was impeded if the materials were easy to envisage as visual mental images. Congenitally totally blind participants did not show this visual-impedance effect. Blindfolded participants with normal vision showed the same pattern of performance as the sighted. We conclude that...

This paper describes two studies concerning the use of haptic virtual environments for blind people. The studies investigated the perception of virtual textures and the perception of the size and angles of virtual objects. In both studies, differences in perception by blind and sighted people were also explored. The results have implications for the future design of VEs in that it cannot be ass...

Smartphones with sensors such as accelerometer and gyroscope can be used as pedometers and navigators. In this paper, we propose to use an LSTM recurrent network for counting the number of steps taken by both blind and sighted users, based on an annotated smartphone sensor dataset, WeAllWork. The models were trained separately for sighted people, blind people with a long cane or a guide dog for...

This paper describes the development and evaluation of a haptic interface designed to provide access to line graphs for bind or visually impaired people. Computer-generated line graphs can be felt by users through the sense of touch produced by a PHANToM force feedback device. Experiments have been conducted to test the effectiveness of this interface with both sighted and blind people. The res...

The aim of this study was to compare the HIV/AIDS knowledge and accessibility to HIV/AIDS information between blind and sighted individuals in Nigeria. A cross-sectional survey was undertaken among rural and urban blind (57) and sighted (62) adolescents in 2006. A structured questionnaire was used to collect data about HIV/AIDS symptoms, transmission and prevention knowledge, as well as accessi...
