Definition[edit | edit source]

The Wii balance board is a controller for the Nintendo Wii gaming console.

balance board (Wikipedia)

It is possible to hook it up with a PC. You then can use it as an input device, e.g. like a joystick.

Surfing the Internet[edit | edit source]

The idea: Surf on the Web with your feet only. This is a first attempt ...

Material:

A DELL XPS II Laptop with a bluetooth card
Adapter is Toshiba
Driver is "Bluetooth Personal Area Network from Toshiba" - Version 5.0.2129.0 of 27.11.2002
Bluetooth HID port from Toshiba
Nintendo wiimote + nunchuk and a wii balance board

Wiimote hookup[edit | edit source]

To set up the bluetooth connection for the wiimote

Hook up the nunchuk ! ... else (I think) it won't be calibrated right and you will have to delete bluetooth connect
Launch the Bluetooth program (Menu Programs->Bluetooth->Bluetooth settings)
Click on "new connections", express mode
Press on the wiimote at the same time button 1 and button 2 (or alternatively the red button inside the battery trap)
Create a blue moon shortcut on the desktop

... and it should work, basically it's like connecting a cell phone or any other bluetooth device, i.e. straight forward with this laptop at least.

GlovePIE Scripts[edit | edit source]

The Wii balance board is supported by Carl Kenner's GlovePIE v. 0.3 + on the PC.

Donwload and install this software
Then get some PIE scripts that emulate mouse behavior (update: the site I got my scripts from is dead / Daniel K. Schneider 12:58, 20 July 2010 (UTC))

I based my trials on WiiMouse Version 0.4 by Sam Braidley (just appended what's below to it)

Balance board hookup[edit | edit source]

To set up the bluetooth connection for the wii balance board

In the bluetooth program, click on "new connections"
Open the battery case of the board and press the red button

What I get is:

Nintendo RVL-WBC-01
00:1E:35:FD:7D:B5
Périphériques(Manette de jeu)
Nintendo RVL-CNT-01

The documentation for the GlovePIE v 0.3 balance board support is on page 70. It works :) ... there is only some weird calibration to do (e.g. I find the X and Y axis of the Joystick interface mixed up.

Balance board script[edit | edit source]

I added this (in several variants) to an existing PIE script

// Put the LED on
Wiimote2.BalanceBoard.LED = true

// This may look really weird. What is X and Y is a question of opinion ;)
// (1) For me, X should be handled by left/right when board is in normal position in front of TV. Glove PIE X is front/back.
//               on/off LED
//    +--------------------------+
//    | FL                    FR |
//    |     left        right    |
//    | BL                    BR |
//    +--------------------------+

// (2) on/off button is IN FRONT, i.e. close to computer, else multiply by -1
// Calibration (x and y offsets) are a bit strange. Seems to change over time also.
// Finally, there is some Interaction with the Wiimote I don't understand.

// Ajust values here - you may have to change them each time
// When you don't stand on the board, data for FL and BR are weird.
// Below a formula that leaves the cursor more or less idle when NOT on the board
var.deltaX = (Wiimote2.BalanceBoard.JoyY - 0.00) / 25
var.deltaY = (Wiimote2.BalanceBoard.JoyX + 0.05) / 25

// When you stand on the board (in neutral position) things may be wrong. So you may to compensenate once you are on the board...
// var.deltaX = (Wiimote2.BalanceBoard.JoyY - 0.20) / 25
// var.deltaY = (Wiimote2.BalanceBoard.JoyX + 0.15) / 25

mouse.x = mouse.x + var.deltaX
mouse.y = mouse.y + var.deltaY

debug = "BB= " + Wiimote2.HasBalanceBoard + " JoyX =" + Wiimote2.BalanceBoard.JoyX + " JoyY =" + Wiimote2.BalanceBoard.JoyY + " FL=" + Wiimote2.BalanceBoard.FrontLeft + " FR=" + Wiimote2.BalanceBoard.FrontRight + " BL=" + Wiimote2.BalanceBoard.BackLeft + " BR=" + Wiimote2.BalanceBoard.BackRight

Greasemonkey script[edit | edit source]

When you surf on the Internet you don't want to click, but just ride. To do so you have to write a Greasemonkey script like this.

Greasemonkey is a quite spectacular FireFox extension that allows you to customize the way a webpage displays using small bits of JavaScript. Hundreds of scripts, for a wide variety of popular sites, are already available at UserScripts.org. Something similar exists for Opera. IE 7 we don't know. Below is the script I wrote, you can copy/paste or get it from here

// ==UserScript==
// @name           Mouseover surfing
// @namespace      DKS
// @description    Adds a mouseover event handler to internal each link of a MediaWiki that will redirect to a new page. This is for surfing a Mediawiki
// @include        http://tecfa.unige.ch/guides/js/ex/greasmonkey/
// ==/UserScript==

var n=document.links.length;
// Change the cursor into something that is bigger
document.body.style.cursor = "url(http://tecfa.unige.ch/guides/js/ex/greasemonkey/cursor.png) 25 25, auto";

for (var i = 0; i < n; i++) {
  l = document.links[i];
  l.addEventListener(
     'mouseover',
     function(event) {
       var link = event.target;
       // link.style.cursor = "crosshair";
       link.style.cursor = "url(http://tecfa.unige.ch/guides/js/ex/greasemonkey/cursor-link.png) 25 25, auto";
       // Uncomment to constrain to mediawiki internal links
       // if (link.className!="external text") 
       if (link.href) document.location.href = link.href;
     },
     true);
 }

This little script should be improved, e.g. by waiting a second before loading a new page. I'll do this once I have time, based on the code of NoClick 1.00.A.

The result[edit | edit source]

Result is not perfect, but it does ok for a let's ride the Internet demo. I put it on YouTube (sorry I am not a filmmaker ...): http://www.youtube.com/watch?v=bqTB5AUDZzo
