You can use the Wiimote for controlling the viewer. Why use a wiimote?! I thought you would never ask. Using a wiimote, you have much superior control and oversight when you're in a presentation situation. Imagine yourself showing something in-world to your co-workers/friends, while you have to control a mouse and keyboard, sitting in a horrible chair.

With the wiimote you can run around, serve coffee, and let your buddies control it without asking them to come over. Enough propaganda. Let's get to it.

You can use the Wiimote(Plus) and the nunchuck for controlling the viewer. Using a wiimote, one has a powerful freehand 3d-controller which has all the options to navigate freely when in a presentation situation. The software used is [http://abstrakraft.org/cwiid/ cwiid]. Cwiid lets you control the accelerometer, the ir-camera, and every button on the wiimote and nunchuck through the use of config-files.

The software i'll be using is [http://abstrakraft.org/cwiid/ cwiid] (Not available on Bill OS though). Cwiid lets you control the accelerometer, the ir-camera, and every button on the wiimote through the use of config-files. The hardware i'm using: 1 Wiimote(~40 euro), 1 ir-pointer(ir-led, 2 1.5V batteries, 1 on/off switch, an empty marker to stuff it in)(~10 euro), and a bluetooth dongle(~15 euro). Once the bluetooth dongle is running(check out the bluez-libs/bluez-utils), you'll be able to fire up wminput. It has some standard configfiles for functionality. Find out where the config-files are(one is called "ir_ptr"). Make a new file named "opensim" in the same directory, and fill it with:

There are basically 4 essential keys that the viewer uses, but the wiimote interface is not really suited to control 4 buttons within the hand's normal reach. So - lets have a look at that configfile again - you can see that the right mouse-button is out of alignment with your normal handposition on the wiimote. You normally won't use that button(option menu) as often as the other onces. The buttons within reach are all configured to control the way you position the camera. A-Button is mouse leftclick(select object, select pivot-point), The B-Button is yaw, and digital-down is pitch.

Now, it would be better if we also had a nunchuck(just gonna buy one soon). With a nunchuck we acn relieve the moving-controls to the analogue controller.

[edit] Overview

You can use the Wiimote(Plus) and the nunchuck for controlling the viewer. Using a wiimote, one has a powerful freehand 3d-controller which has all the options to navigate freely when in a presentation situation. The software used is cwiid. Cwiid lets you control the accelerometer, the ir-camera, and every button on the wiimote and nunchuck through the use of config-files. The hardware used: 1 Wiimote(~40 euro), 1 nunchuck(~20 euro), 1 wireless wiibar(~15 euro), and a bluetooth dongle(~10 euro).

[edit] Procedure

  • Install the bluez libraries (libbluetooth3 and libbluetooth-dev)
  • Run the bluetooth daemon
  • Download and compile cwiid from git 
git clone https://github.com/abstrakraft/cwiid.git
cd ./cwiid
aclocal
autoconf
./configure 
make
make install
  • Or you can simply download wminput and wmgui via apt-get or so. 
apt-get install wminput wmgui
  • Make a new configuration file for wminput, and fill with the wiimote-only or wiimote-nunchuck(prefered) setup 
vi /usr/local/etc/cwiid/wminput/opensim

[edit] Wiimote-Only

There are basically 4 essential keys that the viewer uses, but the wiimote interface is not really suited to control 4 buttons within the hand's normal reach. So - lets have a look at that configfile again - you can see that the right mouse-button is out of alignment with your normal handposition on the wiimote. You normally won't use that button(option menu) as often as the other onces. The buttons within reach are all configured to control the way you position the camera. A-Button is mouse leftclick(select object, select pivot-point), The B-Button is yaw, and digital-down is pitch. 

#ir_ptr
include buttons
 
Plugin.ir_ptr.X	= ~ABS_X
Plugin.ir_ptr.Y	= ~ABS_Y
Wiimote.A	= BTN_LEFT
Wiimote.Plus	= BTN_RIGHT
Wiimote.B	= KEY_LEFTALT
Wiimote.Down	= KEY_LEFTCTRL

[edit] Wiimote-Nunchuck

With a nunchuck we can relieve the moving-controls to the analogue controller. Also, the down-button linked to left-ctrl is somewhat a hack. It works, but it's not the most natural approach possible. The wiimote-nunchuck configuration: 

include buttons
 
Plugin.ir_ptr.X = ~ABS_X
Plugin.ir_ptr.Y = ~ABS_Y
Wiimote.A = BTN_LEFT
Wiimote.B = KEY_LEFTALT
Nunchuk.C = KEY_LEFTSHIFT
Nunchuk.Z = KEY_LEFTCTRL
 
Wiimote.Up = KEY_PAGEUP
Wiimote.Down = KEY_PAGEDOWN
Wiimote.Left = KEY_LEFT
Wiimote.Right = KEY_RIGHT
Wiimote.Plus = BTN_RIGHT
Wiimote.Minus = KEY_B
Wiimote.Home =KEY_M
#Wiimote.1 = KEY_PROG1
#Wiimote.2 = KEY_PROG2
Plugin.nunchuk_stick2btn.Up = KEY_UP
Plugin.nunchuk_stick2btn.Down = KEY_DOWN
Plugin.nunchuk_stick2btn.Left = KEY_LEFT
Plugin.nunchuk_stick2btn.Right = KEY_RIGHT

Notice the Plugin.nunchuck_stick2btn, which is only in the git-version of cwiid.

  • Load the uinput kernel module 
modprobe uinput
  • Start wminput with the opensim config 
wminput -c opensim
