yonyz Posted March 13, 2011 Posted March 13, 2011 Hi, I have recently stumbled upon a head tracking program called Cachya. From what I've read, it tracks a piece of paper that the player puts on a hat. I have seen videos demonstrating its accuracy, and it seems to work great. So I've downloaded the trial version from Cachya.com, but when I choose my webcam as the tracking source, the program crashes. I have tried all versions of the program. The website has a forum, but it's dead. No one responds there. Also, some reported not getting an activation key, after paying for the application (which is $15, I believe). Anyway, I'd like to know if there's anything I can do to stop the program from crashing. It gives me the following error: "The instruction at 0x0040f6ae referenced memory at 0x6111001. The memory could not be read. Click on OK to terminate the program." Please give the program a try so I would know if the problem is my PS3 Eye. Keithb77, if you're reading this, give it a try, will ya? The program is just a few MBs, so don't be afraid.
martinistripes Posted March 14, 2011 Posted March 14, 2011 Try this. It's free and much better and you don't need a silly piece of paper. Read through the thread and experiment to find the right settings. http://forums.eagle.ru/showthread.php?t=56837 I bought Cachya in beta shortly before they abandoned the project.

yonyz Posted March 14, 2011 Author Posted March 14, 2011 I have tried it already, but couldn't get it to behave the way I want it to. It's either too sensitive or insensitive, and I especially can't get it to let me look down the cockpit, especially when looking to the sides, because I turn my head too much and it looses track of my face.
Irregular programming Posted March 14, 2011 Posted March 14, 2011 Did you install it as an administrator? (I have never heard of the program before so I can't really help you more than throw out some ideas)
yonyz Posted March 14, 2011 Author Posted March 14, 2011 You mean, by using "Run as administrator"? No, I didn't, but my user account IS an administrator.
isoul Posted March 14, 2011 Posted March 14, 2011 I 've tried it before buying TrackIR. I found that, while it tracked, in general, the movement of my head, it was sometimes too sensitive while some other times wasn't tracking it correctly or wasn't tracking it at all. Of course the tracking was depending on light conditions in the room quite much. Compared to TrackIR its a "day and night" comparison. I believe the main source of problems Cachya has are derived from the dependability on tracking high contrast areas of the image (the reason you use a black&white "goofy paper" on your head). AFAIK TrackIR, for example, tracks IR light produced by IR LEDs and captured by an IR camera. This works great since you have few to none IR sources in your room. On the other hand Cachya follows high-contrast area (bright colors such as white) captured by a normal camera. You understand that there might be more that one "bright color" in your room (generated by sunlight, a spotlight or just a deflection) so these will easily interfere in the tracking process. Of course Cachya's price cannot be compared to TrackIR. Still, personally I believe its TrackIR or nothing.
yonyz Posted March 14, 2011 Author Posted March 14, 2011 I have decided to not invest any more time on Cachya and FaceTrackNoIR. I will order a TrackClip Pro, remove my PS3 Eye's IR filter (if necessary), and see how it works out. Due to the price of TrackIR in my country (220 USD, not including the clip), it's either FreeTrack or nothing. :D
