This oscillation is also clearly visible when previewing the /tui/2D/cur/x position for instance. Although I was very careful to align the two calibration, the parallax between the two wiimotes probably offsets the calibration points slightly, resulting in different calculated coordinates.ĭoing a very inaccurate of the two wiimotes on purpose results in even larger oscillation. As I move the cursor with the IR point, the cursor oscillate between two positions, but this oscillation stops as soon as I obstruct the view from one wiimote, at which point the cursor stabilise (very smoothly) to the other wiimote's tracking. The wiggling cursor effect is clearly the result of the slightly different calibration of the two wiimotes in OSCulator. My point is that single Wiimote data should work well for a start in OSCulator, then we can look into adding more Wiimotes.The tracking with a single wiimote is very smooth and stable. OK, have you tried with a single Wiimote?ĭo you also have a wiggling cursor effect? Note that I have tried to select multiple wiimotes (by selecting several units in the Wiimote device list with the Command key down) and clicking on the TUIO "Calibration" button, hoping that it would calibrate all the selected wiimotes at the same time.īut that didn't work: same wiggling cursor effect. Or am I misunderstanding how that works in OSCulator? So my question: is there a way to calibrate all wiimotes at once? WiimoteWhiteboard had an simple way to calibrate all wiimotes at the same time, so that the 4 calibration IR "clicks" would be seen at the same time by multiple wiimotes, resulting in very stable cursor position in use. This, however, results in rather jumpy cursor position when assigning a Mouse (absolute X & Y) event to /tuio/2D/cur/0, as any slight misalignment between the different calibrations causes the cursor to wiggle. However, when using several wiimotes to "watch" the same canvas, the calibration needs to be run on each wiimote, rather that all calibrating at the same time. It seems that, when the TUIO option is activated on a wiimote, it requires through a calibration process (4 points to "click" with the IR LEDS). #USING THE IR AND WIIMOTE OSCULATOR HOW TO#I have been playing with the whiteboard functionality this morning to review how to calibrate the system. So this is basically a standard whiteboard setup. The two Wiimotes are useful to avoid self shading of the IR points while we work on the canvas. Our set up uses 2 wiimotes (or ideally more), overlooking from two different angles a video projection of a large paper canvas (roughly 1.5 x 4 m) laying on the floor, on which we are using real paintbrushes and pencils equipped with small IR LEDS. #USING THE IR AND WIIMOTE OSCULATOR LICENSE#When it did work, though, the output was very simple to process in Processing (simulating mouse drag when a IR point appeared on the canvas).Īs we were already using OSCulator to route the OSC from the Processing program and the musician's MIDI instruments, I looked yesterday into the possibility of using it also for the Wiimote and was delighted to discover that the new version supported whiteboard application with wiimotes! So first of all, thank you Camille! Of course, I immediately bought a second license for Osculator. #USING THE IR AND WIIMOTE OSCULATOR SOFTWARE#This has not worked so well, with both a very limited set of different wiimote models that could connect to that software and rather unstable/messy connection process. We have so far been using WiimoteWhiteboard ( ) in the past to track IR points for our art performance Ooo-Ya-Tsu ( ).
