@andy, michael and thiago Thanks for clarification and sorry for late reply due to holiday.
As you had pointed out, what my point is exact the position API. Because of the in-accurate position info from only 6-axis (accel+gyro), some vendors had developed arithmetic which fusion the data from 9-axis and do the accurate remedy for 6-axis data, mainly from joystick and game in customer electronic industry. >From the original question from Terence, I assume those vendors are meaning >they had similar 'motion processing' from not only HW but also SW for accurate >position identification. Now, those remedy processing should be non-opensource, so if some libraries can abstract/fusion those processing, that would be great for improving the experience, those kind of abstract can be from other components, (maybe) also can be from QT if possible. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Andy Ross Sent: Saturday, June 04, 2011 12:22 AM To: [email protected] Subject: Re: [MeeGo-dev] QtMobility API to support 9-axis Motion processing On 06/03/2011 05:20 AM, Thiago Macieira wrote: > PS: I can't find any relevant documents on "fusion arithmetic" on the > Internet. > Can you share some links? This whole "9-axis" thing is new to me too. I found a press release that uses the term, along with "sensor fusion": http://cdiwebblog.wordpress.com/2011/04/27/invensense%C2%AE-unveils-smartmotion%E2%84%A2-platform-with-9-axis-motionfusion%E2%84%A2-engine/ As everyone has already pointed out: inertial navigation algorithms aren't part of a platform abstraction API. Qt Mobility doesn't provide it for the same reason that you don't find a DCT implementation in OpenGL or 3D vision algorithms in your camera driver.
