5.2. Gesture Sensing
In addition to infrared and ambient light measurements and distance calculations, the example firmware contains
algorithms for gesture recognition. When connected to the board with the Performance Analysis Tool, a group
window will appear, as shown in Figure 6. When a gesture is recognized by firmware, the gesture name and
parameter information will be added to the top of the 2D Gesture group. Three gestures are supported by the
example code. The parameters for each gesture are listed in Table 2.
