Transparent display devices will provide a new user interface in the future.

muRata had a demo with Origin Wireless to show the possibility of radio sensing by existing Wi-Fi technology. When a radio wave is emitted from a Wi-Fi point, radio wave reflection occurs in the space. If there is a change of the reflection time, it means some physical object movement events have occurred. Origin Wireless called their algorithm as “Time Reversal Machine” technology. It can have a wide range of applications including watch-over service, security system and indoor position system. It provides the accuracy in 1~2 cm. Without any calibration, it also can achieve 10~20cm. Before the CEATEC, Origin Wireless secures $10.5 in Series B financing. muRata also had additional participation in this financing.
