Guidelines for Designing Mobility and Orientation Software for Blind Children

Abstract

Abstract. We present a study about the use of current electronic travel aids to help blind people navigate through familiar and unfamiliar environments. We also discuss the main strengths and weaknesses of electronic travel aids and propose guidelines to design and use them adequately. We provide a proposal to develop and use traveling aids. As a result, this can be a first step towards defining major aspects to develop travel aids oriented to assist mobility and orientation of blind people.

Audible Beacons and Wearables in Schools

“…For example, the functionality in Scenario 1 might be used during some play sessions and the functionality from Scenario 2 (awareness of friends) may be used at different times, when social play is to be encouraged. These findings agree with recommendations by Sanchez and Elias [27] to minimise the risk over short-term memory overload.…”

“…These systems, and others like them, use sound to tell users where nearby points of interest are, although they did not present other information about them. We consider a different approach in this paper, as giving visually impaired children information about points of interest might help them orient themselves more effectively [27] or encourage them to seek a new activity.…”

“…However, they also found that the amount of information could overwhelm. Sanchez and Elias [27] also discuss the risk of overload; a balance between quality and quantity of information is important.…”

“…"at two o'clock"). Sanchez and Elias [27] also provide recommendations for relevant and useful information presentation. The wayfindr [34] standard gives guidance on presenting audio cues for wayfinding, focused on smartphone and beacon use.…”

“…That work demonstrated some potential benefits of creating games from auditory cues. Turning assistive cues into games might also encourage the children to engage more with the technology, increasing its benefits [27].…”
