Multi-Touch Screen Using Wii Remote

[Bernardcruz20]

dont knw wat multi means?

@MustafaVideocast Please see the link in the video description to Johnny's page. All the software you need is there.

[builderbearlover33]

Cool!

[Sambora500]

@builderbearlover33 Thanks =)

does it work on a TV

[LTao123]

Awesome video! I might try and make something like this in the holidays when I have time. One thing I want to know though. Do I need to have a wii remote somewhere across the screen so it has to see? where exactly do I put the wii remote? Also, what does the pen do? Does it shine the infra red light onto the screen and reflect into the wii remote's camera? Cheers

[betuna75]

hey good job !! i have a question i wanto make a drawing tablet becouse i do graphic design but i dont have a camara or in onother case a wii control like other projects but i do have a :eHome Infrared Transceiver with its remot control can i use my reciever to recieve my remote control signal but converted in a pen? instead of using a wii or a led pen? have you tryed the wii project? please help !!

[Sambora500]

@betuna75 Don't think it would be that easy to incorporate the eHome unit into multitouch applications. You would need to play with a lot of software to get this to work... The wiimote is still the easiest and cheapest option.

[monkey4526]

intresting...make a step by step video how to make the pen with the light?

[keyinregulus3]

Hi I'm just wondering, is there a way to do this from a distance, like with a laser instead?

[Sambora500]

Yeah sure as long as the Wiimote can see the pointer. I have tested an IR Laser module with success...

[keyinregulus3]

What about one of those cheap red laser pointers you see at pet stores, that used to be really popular in the 90's?

[xtruma]

im pretty sure u could... since all sources of IR are compatioble... the bottom line is thatthe IR has to be strong enough to be detected by the WII remote sensor...thats all

[mrfourtysevenman]

download phun beta 5.

use the touch screen wiimote with it.

be amazed.

[Disneychanne1]

In theory, if you can connect to the wiimote you should be able to connect to the wii?

Maybe if it doesnt work try making it think your pc is a wiimote

[girlsdrinkfeck]

thats not touch screen , technically its IR tracking , u can even buy a Ir laser and use that to point at a display for the wiimote to track wilst sitting down on the sofa

[puernatusest]

hey do I need to get a bluetooth special adapter, or anthena for the computer? Thanks for your answer i have never used a blue tooth neither on my cell phone, I just know the theory behind the technology but i have never seen one or know how it works with the computer

[puernatusest]

Hey, I saw the videos I have the software, what I dont understand is: how does the Wii comunicates with the computer?

I am a teacher I would love to do this with my students

[Sambora500]

Hi there, the Wii remote communicates with the computer via BlueTooth. Once a connection is established via Bluetooth, the Wiimote (which is actually an InfraRed (IR) camera) detects the IR light being emitted from the IR Pen and creates a 'blob' or mouse co-ordinate. So using Johnny Chung Lee's software & Bluetooth software (BlueSoliel) the WiiMote can send that information via Bluetooth to the PC. A nice 'Wireless' multi-touch screen =)

[SuperOnionFruit]

Johnny Lee rules LOL

[Sambora500]

Yes...Yes he does =)

[Envee211]

Holy shit, how did you do this? Link? I have long wanted to be able to draw pictures ON my monitor with smooth results.

[Sambora500]

I've added the link in the "more Info" section of the description.

[jimihertz]

it's single touch......

[Sambora500]

The application I'm using simulates the mouse, single touch, however the Wiimote has 4 IR sensors built in, so multi-touch applications such as Finger Tracking or Johnny Chung Lee's Grid program would work. I used Paint (which is not multi-touch), whereas the Wiimote Plugin and NASA World Wind allows 2 finger zoom etc...

[kaokong]

so pretty much, the stronger the LED light and position of the wiimote, the better the results?

[Sambora500]

pretty much. The Wiimote MUST be able to see the light emitting from the LED at all times.

[alex681219]

The leds have an specific angle that emits more ir light(the front), but in the sides the light is weak...is there more powerfull leds?, I go to the electronic shop but just have remote control leds, and see one big led 5mm but dont have in stock.

Butt i think if you and every body have normal irleds and the wii board works fine maibe the problenm is the angle of the wiimote...i will try with ftir...seee you

[alex681219]

tks!! I made other pointer but not works until point directly the wiimote...i buy remote control leds and put 3 volts to it.

The wiimote seems like not view the ir led...i see the led in my cellcam and have just tiny spark...

[alex681219]

change the bateries, and works better... now the cursor jump and I want that run smoot some ideas???

[Sambora500]

normally the cursor will jump around if the IR LED brightness is too low. You can see from my video that the brightness of my LED is high. If you're using a 3V supply (2 AA batteries), then you need to apply a 15 to 30 Ohm resistor. Have you done this?

[alex681219]

No...what color stripes have that resistor?

Scuse my ignorance..if no have resistor the light must be bigther because more current is passing trought the led? or I´m wrong?

Now the blue soleil stops over 5 mgbites of data transfer...and my bluetooth disk have an old version...i will try to install that TKS

[Sambora500]

Brown, Green, Black... for 15 Ohm. If you don't have a resistor, the IR Led life will be shortened, it should be brighter(depending on LED) but you will eventually kill the LED. The resistor makes sure only the correct amount of current is supplied to the LED. Depending on the remote IR LED's current drop, you may need a different resistor.

[alex681219]

tks...

[spursboy1994]

how did u make the light pen?

[Sambora500]

Firstly I hacked open a remote control, stole the IR LED and connected it to a momentary switch. I used the casing of a regular pen to hold the wires and button. Then I added a resistor (68 Ohm) because I was using USB (+5v) as a power source. (Depending on power, you'll need to vary the resistor value.)

I would suggest going to Johnny Chung Lee's Wii projects page. He has a schematic of his pen.

[alex681219]

Nice and smoot

[Sambora500]

Thanks, All credit to Johnny Chung Lee :)

[alex681219]

I try yesterday to make a solid state IRpen with clock batteries, works fine, but when I try to callibrate seems like the IR led pulses creating in one click 4 clicks.Maibe is the battery that no have good contacts.

Where you put the wiimote some sugestions?

[Sambora500]

You can't see from the video, but it's about 45 degrees from the monitor I'm pointing at. Also it was roughly 20cm off the desk and about 15 degrees angled up. Basically, the Wiimote MUST see the lightpen at all times. I tried for a while to get the right spot. A tripod above the monitor would be the best bet. The problem you're facing might be that the Wiimote is too close and picking up more than one blob. Try moving the wiimote back until you only detect 1 blob.
