Guest denizkoekden Posted February 25, 2011 Report Share Posted February 25, 2011 Hi, I tried Multitouch at the Advent Vega from a friend (we live in europe so its an PoV Mobii) and it only has Support for 2 Fingers! I dont know why :/ Wiki says "The capacitive screen has a 1024×600 resolution and supports four-finger multi-touch"... He has latest MoDaCo Custom Rom Installed to the Tablet, ist this why it doesn't work? Regards Link to comment Share on other sites More sharing options...
Guest obb Posted February 25, 2011 Report Share Posted February 25, 2011 The Vega only supports two fingers regardless of the Rom installed ... In all honesty I cant see why needing more than two fingers is going to be a problem 99% of the time Link to comment Share on other sites More sharing options...
Guest Lennyuk Posted February 25, 2011 Report Share Posted February 25, 2011 Before I got the vega I was lead to believe it had 4 finger, but this was only poor advertising/reviewing it does only have 2 finger support, however unless your playing a game it doesn't really make any difference.

Guest worto03 Posted February 25, 2011 Report Share Posted February 25, 2011 I thought it had 4 finger support too - can't say I've noticed\missed it in the last 3 months, every spec sheet I can find on the internet says 4 finger but the official advent specs never seem to mention it either way.

Guest denizkoekden Posted February 25, 2011 Report Share Posted February 25, 2011 May the Hardware supports it but the Kernel does not :huh: We have to try! :) Link to comment Share on other sites More sharing options...
Guest newbe5 Posted February 25, 2011 Report Share Posted February 25, 2011 May the Hardware supports it but the Kernel does not :huh: We have to try! :) AFAIK Apple have a Patent on full multi-touch and so not a single android device has more than 2-point touch capability.

Ah well I must be wrong :P I know the way that android deals with multitouch is different to apple, because Apple devices actually detect individual screen touches as separate contact events, whereas Android devices (because of the patent) have to draw vertex points between the multiple touches and calculate the events based on distance etc. But yea, the Vega is only 2-point touch :huh: Link to comment Share on other sites More sharing options...
Guest AntiCatalyst Posted February 26, 2011 Report Share Posted February 26, 2011 Ah well I must be wrong :P I know the way that android deals with multitouch is different to apple, because Apple devices actually detect individual screen touches as separate contact events, whereas Android devices (because of the patent) have to draw vertex points between the multiple touches and calculate the events based on distance etc. Wrong again. :huh: Android detects separate touch events for every finger on the screen. Just look here This is the relevant part, an event log of a pinch gesture 1. event ACTION_DOWN[#0(pid 0)=135,179] 2. event ACTION_MOVE[#0(pid 0)=135,184] 3. event ACTION_MOVE[#0(pid 0)=144,205] 4. event ACTION_MOVE[#0(pid 0)=152,227] 5. event ACTION_POINTER_DOWN(pid 1)[#0(pid 0)=153,230;#1(pid 1)=380,538] 6. event ACTION_MOVE[#0(pid 0)=153,231;#1(pid 1)=380,538] 7. event ACTION_MOVE[#0(pid 0)=155,236;#1(pid 1)=364,512] 8. event ACTION_MOVE[#0(pid 0)=157,240;#1(pid 1)=350,498] 9. event ACTION_MOVE[#0(pid 0)=158,245;#1(pid 1)=343,494] 10. event ACTION_POINTER_UP(pid 0)[#0(pid 0)=158,247;#1(pid 1)=336,484] 11. event ACTION_MOVE[#0(pid 1)=334,481] 12. event ACTION_MOVE[#0(pid 1)=328,472] 13. event ACTION_UP[#0(pid 1)=327,471] pid 0 and 1 are two separate fingers. Note how they are both recorded individually with their own X/Y coordinates. The apple multi-touch patent thing is a myth at best. Either that or they're just waiting for Android to become a big enough threat before taking any legal action :) Link to comment Share on other sites More sharing options...

For android 1.0 :-P Proper multitouch support was added after 1.6 it seems! Link to comment Share on other sites More sharing options...
Guest Nitromouse Posted March 23, 2011 Report Share Posted March 23, 2011 (edited) Are there some news about multi touch support? I would need this because want to develop an app using more than 2 fingers. Wouldn't it be easy to unlock this in the kernel? Would be nice if anybody would inlcude this in future ROMS.

But I am not that kernel guy, don't have an idea of that. That must do someone with knowledge in this area ^^ Link to comment Share on other sites More sharing options...
Guest Nitromouse Posted March 23, 2011 Report Share Posted March 23, 2011 I found this: http://forum.xda-developers.com/showthread.php?t=878936 Does anybody know if Vega uses the same controller?

Or which touchscreen controller the vega uses? Michael It would be great if we could do this with the vega, the ipad has just gained gestures to be back at the home screen in the 4.3 firmware. It would be nice to get something like that in the vega. Saves on the hardware buttons and it would be much more practical Link to comment Share on other sites More sharing options...
