Chance

This dynamic art I made in 2019 is what inspired me to come up with the sensor idea.

The LEDs are likened to small creatures, and when a pencil is brought close to them, they gather. Scatters when moved.

New Interface

This is an early work I took in 2019.
The mode selection method, which selects from 6 glowing dots, is inspired by the Japanese animation Kemurikusa. It is interesting that the cube type can create new interfaces such as selection methods as well as control.

Improved sensor cover

In the first prototype, such as the paper airplane video above, aluminum foil was wrapped. Now I cut the PVC cap and use it. One of the reasons why photo reflectors have not evolved is that it takes time and effort to cover the sensor, but this has now been resolved.

The second from the left is a prototype with two infrared LEDs. I stopped using this because it didn't work.

Non-contact switch

I have several ideas for non-contact switches, but I think the following insertion type is the easiest and does not cause false positives.

Intrusion detection

You can also do this by arranging sensors under the floor.

Antenna device

The last is the antenna device that I am going to experiment from now on. The sensing content is transmitted to the fingertips with a vibration motor. It is convenient because it can detect a wider range faster than a cane. I also hope that this sensor will be useful for visually impaired people.
