New Delhi: With number of innovations being done in the field of health, this comes as a significant one.
A team of researchers led by an Indian has developed a smartphone app that can magnify smartphone screen and thus prove beneficial for people having low vision.
Researchers, from Schepens Eye Research Institute of Massachusetts Eye and Ear/Harvard Medical School have claimed that this app can provide better visibility to low-vision users.
The team designed the app that improves upon the built-in zoom feature of smartphones by projecting the display to Google Glass, which users can navigate using head movements to view a corresponding portion of the magnified screen.
"Given the current heightened interest in smart glasses such as Microsoft's Hololens and Epson's Moverio, it is conceivable to think of a smart glass working independently without requiring a paired mobile device in near future," said first study author Shrinivas Pundlik.
"The concept of head-controlled screen navigation can be useful in such glasses even for people who are not visually impaired," Pundlik wrote in the study published in the journal IEEE Transactions on Neural Systems and Rehabilitation Engineering.
The Pundlik-led team developed the head-motion application to address the limitations of conventional smartphone screen zooming, which does not provide sufficient context and can be painstaking to navigate.
"When people with low visual acuity zoom in on their smartphones, they see only a small portion of the screen, and it's difficult for them to navigate around -- they do not know whether the current position is in the centre of the screen or in the corner of the screen," noted senior author Gang Luo.
"This application transfers the image of smartphone screens to Google Glass and allows users to control the portion of the screen they see by moving their heads to scan, which gives them a very good sense of orientation," Luo added.
