As the Korona-ka continues, the need for non-contact technology that can be operated without directly touching the screen or buttons is increasing, and manufacturers are developing new types of sensors.

Japan Display, a liquid crystal panel manufacturer, has developed a transparent panel-shaped sensor that can recognize finger movements about 5 cm away from the screen.



It is a mechanism that detects a weak change in current generated between the screen and your finger, and you can operate it without touching it by simply placing the sensor on the screen of the touch panel.



The company expects to use it in public facilities and restaurants, and it has been introduced in the library in Tottori prefecture from this month.



Nobuo Tsubokura, Chief of the Japan Display Product Planning Division, said, "Amid growing interest in non-contact due to the Korona-ka, we rushed to develop it because we thought that installing it on existing equipment would contribute to society. We would like to further improve convenience." I did.

In addition, Alps Alpine, a major electronic component company, has developed a new device in collaboration with Utsunomiya University.



Combining non-contact sensor technology and technology that displays images in the air, you can operate it by simply bringing your finger close to the light symbol that emerges on the table.



With the aim of putting it into practical use around 2025, keeping in mind that it will be used in elevators and ticket vending machines, it seems that the number of devices that can be operated non-contactly will increase in the wake of the Korona-ka.
