Today’s personal media player’s, or PMPs, screens are too small. Even worse is the solution: bulky glasses with embedded screens (aka head mounted displays) that obstructs the user’s vision. Brother’s solution is a small and light weight attachment that can be fitted to any pair of glasses, which ‘irradiates low-intensity light’ on to the retina Ultimately, the retina is the display and a result it doesn’t completely obstruct vision. Don’t expect this retinal imager until 2010, though.
