Information processing with smartphones and single board computers: Kanamaru Lab. in Kogakuin Univ.
We utilize smartphones (Android, iOS, etc) and single board computers (Raspberry Pi, etc) for information processing.

Some demos are shown below.

Education Support System using Interactive Floor Interface

We developed interactive floor interface (IFI) that enables users to see teaching materials
displayed on a floor and to control it with their gestures.
We also developed an interactive teaching material of wave interference designed for IFI.

A workbench system for job training based on behaviors of worker

We developed a workbench system for job training in which a workbench was used as a display.

This system is based on the following paper.
New smart telescope controlled by tablets

A new smart telescope for settling at sightseeing spots is controlled by web browsers of tablets (Android/iOS/Windows).
We can perform changing horizontal/vertical directions, zooming in/out.

The browser communicates with Raspberry Pi on which node.js is running,
and the motors are controlled by Arduino Uno and motor drivers (L6470).

Controlling Roomba with three wide-angle cameras using web browsers

The roomba with three wide-angle cameras are controlled by web browsers.
Three wide-angle cameras are sufficient for observing all the directions around roomba.
The browser communicates with Odroid U3 on which node.js is running, and six servo motors and Roomba are controlled by Arduino MEGA.
