Rælclear

The transparent interface Rælclear is a device that connects all forms of human-to-human communication.

01 Enjoy communicating while observing facial expressions

The transparent interface Rælclear is placed between you and the person you are facing, and a transcription system is used. When you speak to the person facing you, the voice input from the microphone to the PC, tablet, or smartphone is converted into text, which is displayed on Rælclear, the second monitor. Because Rælclear has high transparency and can be viewed from both sides, one can read the text-converted conversation content while looking at the expression and gestures of the person speaking, which improves the listener's understanding. This is highly valued as a communication aid not only for the deaf, hard of hearing, and those with APD/LiD, but also for the elderly.

02 Facilitating communication between different languages

By using the translation function of the transcription system, it can also be useful for communication between people with different native languages. As global communication expands, it can be a great help in cross-language communication.

03 Supporting more understandable information presentation and space design

The high transparency of Rælclear is also expected to be applied to AR-like uses. By placing Rælclear between not only people but also objects and landscapes and displaying information and effect images associated with them, it will possible to create a production aimed at increasing value.
