Purpose: The purpose of this study was to investigate the telescope use behaviors in natural daily driving people with reduced visual acuity licensed drive a bioptic (a small spectacle-mounted telescope). Methods: A large dataset (477 hours) naturalistic collected from 19 drivers (visual 20/60 20/160 without To reduce data volume, multiloss 50-layer deep residual neural network (ResNet-50) used detect potential events. Then, total 120 hours selected video clips were reviewed and annotated...
Keyword search in a cluttered environment is difficult general, and even more challenging for people with low vision. While magnification can help reading vision people, it does not facilitate efficient visual due to the constriction of field view. The motivating observation this study that, large number tasks, know what are they looking (i.e., keywords), just do where find them scene. We have developed mobile application that allows users input keywords (by voice or by typing), uses an...
There is scant rigorous evidence about the real-world mobility benefit of electronic aids.To evaluate effect a collision warning device on number contacts experienced by blind and visually impaired people in their daily mobility.In this double-masked randomized clinical trial, participants used during over period 4 weeks. A volunteer sample 31 independently mobile individuals with severe visual impairments, including total blindness peripheral field restrictions, who long cane or guide dog...
We conducted a driving simulator study to investigate the effects of monitoring intersection cross traffic on gaze behaviors and responses pedestrians by drivers with hemianopic field loss (HFL).Sixteen HFL sixteen normal vision (NV) participants completed two drives in an urban environment. At 30 intersections, pedestrian ran across road when participant entered intersection, requiring braking response avoid collision. Intersections these events had either (1) no traffic, (2) one...
Purpose: Evaluating mobility aids in naturalistic conditions across many days is challenging owing to the sheer amount of data and hard-to-control environments. For a wearable video camera-based collision warning device, we present methodology for acquisition, reduction, review, coding quantitative analyses outcomes blind visually impaired participants. Methods: Scene videos along with detection information were obtained from chest-mounted device during daily use device. The recorded...
Abstract Individuals with homonymous visual field loss (HVFL) fail to perceive information that falls within the blind portions of their field. This places additional burden on memory represent in field, which may make changes scene more difficult detect. Failing detect could have serious implications context driving. A change blindness driving simulator experiment was conducted individuals HVFL ( n = 17) and those normal vision (NV; 16) where (pedestrians appearing) were triggered based...
Individuals with hemianopic field loss (HFL) fail to perceive visual information that falls within the blind portions of their field. This places additional burden on memory and attention represent in field, which may make changes scene more difficult detect. Failing detect could have serious implications, especially context driving. We used a driving simulator paradigm test hypothesis individuals HFL would be susceptible change blindness than those normal fields (NV) A experiment was...
