It is also possible to touch-operate the screen projected by the projector, an electronic blackboard using the Wii remote control

A reader seems to have produced a tool for conveniently using an electronic blackboard using the Wii remote control that can use the wall surface of the computer screen projected by the projector like a white board.

In addition to being able to write characters on the screen with the electronic pen with the infrared LED mounted on the Wii remote control, you can also operate the PC from the screen of the projector by remote control, and use a pen of the type worn on the finger By doing so, it is also possible to manipulate the screen with a touch operation, which makes it quite useful for those with many opportunities to present.

The Wii electronic blackboard had a bit of history, the first being announced was Johnny Chung Lee of Carnegie Mellon University "WiimoteWhiteboard". We made improvements to this, and "sold as a commercial version"SmoothboardMizukiShirai who gave me a story this time is based on the device which made operability further improved.

The software called "Smoothboard" displays the operation panel on the screen, so you can manipulate the screen projected with a single pen, and if you have a Wii remote control for the presenter you can also operate it remotely With the pen using the bullet-type LED, it is a weak point that you have to operate with two holders because you can not operate it properly if the distance of the Wii remote control for the presenter gets apart.

Therefore Mr. Mizuki Shirai made a device combining infrared LED equipped pen and Wii remote control.

First of all, in order to use the electronic blackboard, it is necessary to have two Wii remote controls and a sensor server attached to Wii, "Smoothboard", Bluetooth, projector, PC.


This is a combination of an electronic pen using an infrared LED and a Wii remote control.


Looking only at the part of the electronic pen is quite compact.


With this remote control, direct writing to the screen and remote operation are also possible.


In this way, you can write letters as if you are squatting on the standard Windows paint screen projected by the projector.


This is a type of electronic pen that fits in your fingers for touch operation. Depending on the material of the wall on the projected side, it seems that the operation may be somewhat unsuccessful, but it is possible to manipulate the projected screen with an intuitive touch operation.


The presentation of this device by Mizuki Shirai can be seen from the following link. If the presentation could be done with such a device, it seems that the range of expressions seems to expand considerably.
