Head Tracking

plán:
- vzít arduino a nějaký obvod akcelerometrem, gyroskopem… použít pro rozhlížení v kokpitu
komplexní návod s MPU 6050
MPU 9250
- lehce sehnatelný na ebay, kolem 120 kč

MPU 9255
- kolem 150 kč, prý nástupce 9250, 9150?
- The new MPU-9255 is the company’s first generation 9-axis activity detection part, working in conjunction with the AAR™ activity detection library.
- The AAR library is required to leverage the full capabilities of this chip. The AAR library is compiled with ATMEL studios for Cortex M4 (ATSAM4LS4A) chipset only.
- The AAR library can be downloaded in our Developers Corner, after signing a click through SLA along with API Document and Integration Guide.
GY-85 9DOF IMU

The MPU-9150 is the MPU-6050 with an extra magnetometer in the chip.

- The MPU-6050 is higher power, lower noise, and larger package versus the MPU-6500. Most of your code should port over, but some low power features are different and will need to be recoded in. Basic data acquisitions shouldn’t have changed.
- The MPU-9150 contains the MPU-6050 and an AK8975 magnetometer from AKM. The MPU-9250 contains a MPU-6500 and AK8963. The same differences between gyro/accel are the same you see with 6050 v. 6500. The magnetometer on the MPU-9250 is a little better across the board.
If I understood the datasheet correctly I think the MPU6050 only has gyro and accelerometer (6 DOF) while the GY-86 is 10DOF and has compass (which helps IMU headtracking alot)

FreeIMU
- nějaký open hardware + knihovny

FreePIE
- sw emulátor různých zařízení.. zkrátka simulace třeba TrackIR, vstup z libovolného zařízení
