K-Glass 3 Smartglasses Enable Keyboard Typing Anywhere

The Korea Advanced Institute of Science and Technology (KAIST) shows off their latest augmented reality smart glasses.

K-Glass are augmented reality smart glasses that were first developed by the Korea Advanced Institute of Science and Technology (KAIST) in 2014. K-Glass 2 was released in 2015, and now K-Glass 3 was unveiled.

The new K-Glass smartglasses allow users to text a message or type in key words for Internet surfing by offering a virtual keyboard for text and even one for a piano.

Professor Hoi-Jun Yoo and his team from the Electrical Engineering Department recently developed K-Glass 3 with a low-power natural UI and UX processor to enable typing and screen pointing on HMDs with just bare hands. This processor is composed of a pre-processing core to implement stereo vision, seven deep-learning cores to accelerate real-time scene recognition within 33 milliseconds, and one rendering engine for the display.

The stereo-vision camera, located on the front of K-Glass 3, works in a manner similar to three dimension (3D) sensing in human vision. The camera's two lenses, displayed horizontally from one another just like depth perception produced by left and right eyes, take pictures of the same objects or scenes and combine these two different images to extract spatial depth information, which is necessary to reconstruct 3D environments. The camera's vision algorithm has an energy efficiency of 20 milliwatts on average, allowing it to operate in the Glass more than 24 hours without interruption.

The research team adopted deep-learning-multi core technology dedicated for mobile devices to recognize user's gestures based on the depth information. This technology has greatly improved the Glass's recognition accuracy with images and speech, while shortening the time needed to process and analyze data. In addition, the Glass's multi-core processor is advanced enough to become idle when it detects no motion from users. Instead, it executes complex deep-learning algorithms with a minimal power to achieve high performance.

Professor Yoo said, "We have succeeded in fabricating a low-power multi-core processor that consumes only 126.1 milliwatts of power with a high efficiency rate. It is essential to develop a smaller, lighter, and low-power processor if we want to incorporate the widespread use of smart glasses and wearable devices into everyday life. K-Glass 3's more intuitive UI and convenient UX permit users to enjoy enhanced AR experiences such as a keyboard or a better, more responsive mouse."

The K-Glass virtual keyboard can be seen in action in the video below. It looks like it only supports two finger typing. Microsoft has so far not demonstrated a virtual keyboard in the HoloLens augmented reality system. The input so far is focused on gestures and voice.
