General Benefit

AbstractMany individuals with visual impairments have residual vision that often remains underused by assistive technologies. Head-mounted augmented reality (AR) devices can provide assistance, by recoding difficult-to-perceive information into a visual format that is more accessible. Here, we evaluate symbolic and alphanumeric information representations for their efficiency and usability in two prototypical AR applications: namely, recognizing facial expressions of conversational partners and reading the time. We find that while AR provides a general benefit, the complexity of the visual representations has to be matched to the user’s visual acuity.

Recent Developments

The information explosion era provides the foundation for a technological solution to enable the visually impaired to more independent living in the community. This paper first provides a review of assistive technologies for visually impaired people. Current technology allows applications to be efficiently distributed and operated on mobile and handheld devices. Thus, this paper also summarizes recent developments of assistive technologies in mobile interaction. It then presents the Wireless Intelligent Assistive Navigation Management System Using SmartGuide Devices for visually impaired people. The “SmartGuide” of the system is built as a standalone portable handheld device. The system is to assist blind and low vision people to walk around independently especially in dynamic changing environments. It also includes a camera sensor network to enhance monitoring capabilities for an extra level of security and reliability. Finally, the paper presents an improved system with some new designs involving mobile interaction.
