Abstract People with visual impairments face substantial navigation difficulties in residential and unfamiliar indoor spaces. Neither canes nor verbal navigation systems possess adequate features to deliver real-time spatial awareness to users. This research work represents a feasibility study for the wearable IoT-based indoor object detection assistant system architecture that employs a real-time indoor object detection approach to help visually impaired users recognize indoor objects. The system architecture includes four main layers: Wearable Internet of Things (IoT), Network, Cloud, and Indoor Object Detection Layers. The wearable hardware prototype is assembled using a Raspberry Pi 4, while the… More >

Abstract Objectives: Adults with cataracts are often reported with mental health issues, which has driven researchers to identify modifiable factors so that effective intervention programs can be timely implemented. Thus, we investigated associations of physical activity (PA) and sedentary behavior (SB) with stress, anxiety, and sleep problems among adults with cataracts. Methods: In this cross-sectional study, a total of 2219 participants with cataracts completed self-reported measures on demographic characteristics (e.g., age and sex), PA, SB, anxiety, stress and sleep problems. Multiple linear regression and logistic analyses adjusted for covariates were employed to examine the associations of… More >

Abstract In 2017, it was estimated that the number of persons of all ages visually affected would be two hundred and eighty-five million, of which thirty-nine million are blind. There are several innovative technical solutions available to facilitate the movement of these people. The next big challenge for technical people is to give cost-effective solutions. One of the challenges for people with visual impairments is navigating safely, recognizing obstacles, and moving freely between locations in unfamiliar environments. A new mobile application solution is developed, and the application can be installed in android mobile. The application will More >
