One of the sub goal of my project is to track the user's head direction and orientation. And I am mostly preferred low cost approach although there are many commercial trackers which are obviously outer range of undergraduate research budget.
When I was conducting my survey, I found many RnD work on affordable head tracking. Among them wiimote tracking is highlighted (and we already have such resource). Therefore I am trying on some APIs which allows wiimote tracing. One such good application is GlovePIE. I have follow some tutorials via the internet and also there is a descriptive documentation with GlovePIE. I have shortlisted some practicals which I have tried myself.
If you have a good oo programing knowladge like c++, this is not that much hard. A comprehensive tutorial can be found here.
So let's take an example expression. It will emulate wii mote right button to the right arrow key of the keyboard.
Key.Right = Wiimote.Right //This can be identified as an object or a variable.
a = var.A //makes a variable A which is equal to the letter a.
In programming syntax,
LValue = expression //set the LValue to the value of the expression.
- GlovePIE is constantly looping through your script.
Hello World ProgramThe 'debug' command will out put next to the stop/run button.
debug = "Hello World!"
This debugger tool is very powerful and it allows us to figure out what is going on in the emulator.
Check Wiimote's Availability and Batterydebug = "Wiimote On:" + Wiimote1.Exists + " Wiimote Battery Level:" + Wiimote1.Battery
Wiimote1.Exists - will be True or False based on whether or not wiimote is ever connected.
Wiimote1.Battery - put up wiimote Battery Level with a number from 0-192 (192 being a full battery).
example output: Wiimote On:True Wiimote Battery Level:104
Calculate Degree of Wiimote is at
- Roll - debug = "Wiimote Roll:" + Wiimote1.Roll
- Pitch - debug = "Wiimote Pitch:" + Wiimote1.Pitch
- Yaw - debug = "Wiimote Yaw:" + Wiimote1.Yaw
So up to now I got some basic knowledge to calculate the coordinates of wiimotes. As I have inspired with GlovePIE I have also tried out following stuffs.
- If condition then statement [ ; ]
debug = "Button A is pressed"
debug = "Other button is pressed"
Once you press a button 'A', it will print "Button A is pressed" and "Other button is pressed" otherwise. According to above example I tried extend it further hence I can figure out what is actually going on in my code.
Can we port this to a game controller ?
debug = "Accelerate"
else if(Wiimote1.B) then
debug = “Break..!”
else if(Wiimote1.Up) then
debug = “Drive”
else if(Wiimote1.Down) then
debug = “Reverse..!”
else if(Wiimote1.Left) then
debug = “Turn Left”
else if(Wiimote1.Left) then
debug = “Turn Right”
debug = "Constant velocity"
Now I thought this conceptual game controller. It will make easier me to debugging.. :)
