Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed smart glasses that offer users a virtual keyboard to type text. The glasses, called K-Glass 3, comes with a stereo-vision camera located at the front of the device. The two lenses of the camera work similar to the way human eyes work, and can sense depth. This allows users to surf the internet and type text using the virtual keyboard, or even play a virtual piano in thin air.
Additionally, K-Glass 3 uses a pre-processing core to use stereo-vision as well as seven deep-learning cores to speed up real-time screen recognition. The researchers say that the camera’s vision algorithm has an energy efficiency of 20 milliwatts on average, allowing it to be used for 24 hours without interruption. The multi-core processor becomes idle when it detects no motion from the user. The team uses deep-learning multi-core technology that is dedicated for mobile devices to recognise gesture inputs. This has improved the glass’s accuracy with images and speed, while also shortening the time needed to process and analyse data.
