One of the shortcomings with smartglasses of the past was a lack of a clean visual experience, i.e., bright images that were always in focus – even in direct sunlight. Bosch has addressed these issues with its optical Light Drive system for smartglasses, an integrated technology stack consisting of miniaturized MEMS mirrors, optical elements, sensors, and onboard processing. The optical systems include microelectromechanical system (MEMS) mirrors with an ASIC controller that precisely directs a low-power beam of light to the user’s eye, helping to eliminate digital fatigue.
These smartglasses provide all-day wearables with perceived total transparency for the user. Social acceptance is enhanced as the glass’s electronics are nearly invisible to others. Additionally, the technology can also be applied to optimize the performance of waveguide systems for which integration packages are in development.
There is no externally visible display or integrated camera, the two pitfalls that have alienated users of other smartglasses technologies. The smaller size allows designers to overcome the bulky, cumbersome characteristics of many of today’s smartglasses. For the first time, a turnkey system enables smaller, lighter, more stylish smartglasses designs that meet the visual and comfort needs of everyone. The tiny module is also big news for those who wear eyeglasses for vision correction - a significant market since six out of ten people use corrective lenses every day.
