FEATURES
POINTING
MoveaTV remote reference kit computes dx/dy mouse data, thanks to the Air Motion Library (embedded) or by sending raw data to
the SmartMotion Server (hosted). It provides pixel-level accuracy, smooth displacement, and tremor cancelation for best-in-class
performance and ease of use.
The pointing computation can be performed from 2-axis Gyro, 2-axis Gyro + 3-axis Acc, or 3-axis Gyro + 3-axis Acc sensors data
fusion.
The raw sensor feature is compatible with any sensors combination, up to 9-axis sensors (3-axis Gyro, Acc and Mag) data fusion.
Note: You can enable ‘AirMotionLib’ with Green + 7 key sequences (see 6 for more information.)
GAMING
MoveaTV BLE remote reference kit computes x/y joystick position, thanks to the Air Gaming Library (embedded) or by sending raw
data to the SmartMotion Server (hosted). It provides high-accuracy, high reactivity and smooth movement for best-in-class
performance and ease of use.
The gaming can be performed with 3-axis Acc + Gyro sensors data fusion.
Note: You can enable ‘AirGamingLib’ with Green + 8 key sequences (see 6 for more information).
ROLL COMPENSATION
MoveaTV BLE remote reference kit implements the roll compensation feature, allowing the user's movement to be reproduced on
the screen, independently from the device roll rotation.
For a semi-dynamic roll-compensation, 3-axis Acc + 2-axis Gyro are necessary. For a full-dynamic roll-compensation, 3-axis Acc + 3-
axis Gyro are necessary.
The computation is either made by the Air Motion Library (embedded) or by sending raw data to the SmartMotion Server (hosted).
Note: You can switch on or off the roll compensation feature with Green + 2 key sequence (see 6 for more information).

EASYCLICK
This feature allows user to perform more accurate and stable mouse clicks for a better experience.
On click press or release, the algorithm will freeze the pointer (i.e. force dX and dY values to zero) for a pre-defined amount of time
to remove undesired movement (button pressing side-effect).
To avoid freezing pointer when not needed (e.g. while performing drag n’ drop operations), device movement quantity is monitored:
if it moves enough after a click, pointer will be released before specified timeout.
Left Click Right Click
CALIBRATION
MoveaTV BLE remote reference kit implements a calibration routine which computes gyroscope offsets values in real time.
If the device is considered static for a certain amount of time (4 seconds), new gyroscope offsets values are computed and a buzzer
will ring to signal the remote is calibrated.
The user has 15 seconds to calibrate the remote and if time is up, he hears 3 short beeps. Time is reset if the Green + 1 key sequence
is performed.
Note: The new offsets will be saved into the EEPROM only if the Green + 1 key sequence is performed (see 6 for more information)
and successful calibration.
GESTURE RECOGNITION
Gesture recognition is processed by the Air Motion Library (swipes), or by the SmartMotion Server (advanced gesture recognition).
Gesture Trigger (press, move then release).

FLIP DETECTION
The flip detection algorithm is used to detect a flip from a 3- axis accelerometer motion sensor. The library can detect if the device
lays on its front side (buttons toward the sky) or back side.
When in pointing mode, if flip detection is enabled, and if remote lays on its back side, then remote stops sending mouse data until
remote is flipped back.
When in raw sensor mode, if flip detection is enabled, and if remote lays on its back side, then remote sends special code inside
frame “key press” field to indicate remote state, but it keeps on sending data unlike pointing mode. This is up to host application to
interpret “key press” field and discard the frame or not whenever remote is flipped.
Note: The library can be turned on or off dynamically by pressing the Green + 5 key sequence (see 6 for more information).

FRAMES FORMAT
BLE frame format:
Basic BLE over the air packets include a 1 byte preamble, 4 byte access codes correlated with the RF channel number used, a PDU
that can be between 2 to 39 bytes and 3 bytes of CRC. Hence the shortest packet would have 80 bits transmitted within 80usec., and
the longest packet of 376 bits will be transmitted within less than 0.3 millisecond.
