Research summary
Visual impairment is a growing concern in society, with especially age contributing to an increasing number of people unable to see sufficiently in order to live independently. While traditional low vision aids have been limited in functionality and usability, in recent years we have seen the start of commercial development on head mounted electronic vision aids. Typically, these systems consist of a camera with an electronic display which can provide a magnified and/or contrast/edge enhanced image of the world. Newer developments in mobile technology have now enabled development of these systems towards a more cosmetically acceptable format, with increased battery life and a superior quality image.
Little is known about the benefits of these devices and it is not clear which people with low vision are most likely to benefit from them. Aim of the present study is to obtain feedback from people with visual impairment on the current state-of-the-art electronic head mounted low vision aids, in order to guide development of the next generation electronic head mounted low vision aids.
The present study will be based around the demonstration of a prototype head-mounted electronic low vision aid at the end of a routine low vision appointment. The prototype was developed using off-the shelf components (smartphone and headset). The smartphone processes a video stream in real time, which the user can view and modify through magnification or one of three image enhancement options. If the patient is willing to try the device, he/she will complete a standardised acuity and reading task and be invited to give feedback on the device. This feedback will be used to inform the development of a market-ready product by the sponsor. The study forms part of a Biomedical Catalyst project funded by Innovate UK in order to inform device requirements.REC name
