Hi all,

This is Gordon from Hong Kong. I serve people with mental disability and this is my modified IR-pen for my service users.

The pen is replaced with a plastic hand-shaped toy such that the click and drag mouse functions can be done with a snap. The switch is located at the tip of the middle finger and seven (weak) IR-emitters are used to generate enough IR signal for the Wii camera (I just can't buy strong IR-emitter in Hong Kong).

I am glad to tell you that my service users really enough the new invention and toy for them, and we are doing educational training and playing games with it.

Good job, Johnny. Keep going!

Gordon from Fu Hong Society, Hong Kong

Hi, Ben,

Your Smoothboard is really great. There is only one feature my service users and I would like you to create. See, the original Smoothboard program assumes all the users have the ability to access the whole projector screen. That is why your calibration screen makes use of the whole computer screen. However, with users sitting on wheelchairs and a large projector screen hanging up 2 to 3 meters above the ground, there is no way the users can access the upper part of the computer screen. Elongating the handle of the IR-pens is one of the solutions but it would be much better if Smoothboard can call-up a small window, which duplicates the entire computer screen and responses to the mouse clicks. In this case, we would do the calibration and play the games with only a small part of the entire screen. Mouse sensitivity will be lowered, but, be frank, our service users really do not need such high resolution like we do. Please kindly help to make it happen.

Hi Gordon,

Smoothboard 1.0 already has a track partial screen area feature that allows the calibration of a part of the screen.

For example, you can set the tracked screen area to be the bottom part of the screen where users are able to reach for using and calibration.


In the above screenshot, you can select the area you will like to track by ticking Track Partial Screen Area and clicking the Select Screen Area to track button.

After choosing the specified area, you can do the calibrations and start using the software.
If the user still can reach other parts of the screen, as long as the Wiimote still can capture the point, the cursor will still be triggered although it is located outside the selected area. To restrict control within the selected region, you can set this under the Cursor Control tab.

Hope this is useful for your users.

Regarding your suggestion of duplicating the functionality of the entire computer screen. It can be done however maybe it should be done through relative motions. Do you suggest for it to work like a laptop's track pad?

Regards,
Boon Jin
