I thought on this instructable when I saw one of my aunts, she has problems when using the computer mouse because her hands tremble a lot due to a illness problem.

In resume this is a modification of the Wii Remote Controller, making it work as a mouse computer.

We will disassemble the Wii remote in order to reach the button actuators in which well solder the ADSL cable.
This is how to disassemble the remote:
1. Dismount the battery cap you will see two screws
2. With the screw driver (I used a special one bought on eBay for one dollar) unscrew the screws.
3. You will now be able to take apart the remote
4. You will see those golden circles (these are the ones were we will weld the ADSL cable)

We will disassemble the bubble tap keychain in order to reach the button actuators in which well solder the ADSL cable.
The keychain popping buttons will be an extension of the Wii remote buttons. (sorry there are no photos of the process but its the same as the Wii remote)

1. At the back of the keychain are two screws
2. Unscrew and dismantle the keychain
3. Dispose the battery (you will not need it more)
4. You will see those golden circles again

Step 4: What to do with the ADSL cable

With the ADSL cable you will make an extension of the Wii remote buttons

1. Weld cable by cable, at the golden ports on the disassembled Wii remote (each port will have two cables).

2. Each port of the remote will need to match with a port of the keychain (I only paired buttons "A", "B", "1", "2").

Sorry for the lack of photos but I was running out of time.

Step 5: Assemble the Remote, Keychain and head-mount

You also will need to put a little isolating tape at the button golden ports for preventing making contact with the original plastic carbon buttons.

Then attach he Remote to the head-mount and that is all.


Step 6: Setting up the computer

Hardware:
1. You will need a wireless remote sensor bar to put on top of the monitor.
2. Also a integrated Bluetooth or external Bluetooth dongle (I used a Toshiba branded Bluetooth).
Software:
1. You will need a Bluetooth driver like (Bluetooth stack for windows by Toshiba).
2. You will need to download the software to make the wii remote act as a mouse (dont worry it is free and you can download it from the link below).

1.-Activate the Wii Remote by touching buttons "1" + "2" at the same time (these would be all ready popping buttons)

2.-Activate the Bluetooth on the computer in searching mode and pair the remote when localized.

3.-Now that is active start the Smoothboard application

4.-Then start the sensor bar that should be on top of the screen

5.-Select the option of presenter and put the popping keychain on your mouth (if the cable is bigger optionally you can put the keychain on the floor or on the hand (it will only function as a clicker)

6.-Now you will be able to move the mouse with your head, and to select links or give clicks you only need to pop the correct button on the keychain.

Step 8: Testing

By experience it is even easier than voice commands and with some practice I already can make some drawing on the windows paint app!
