USING DISTANCE SENSOR DELTA TO DETERMINE WHEN TO ENTER PRESENTATION MODE

An apparatus includes a distance sensor, an image sensor, one or more processors, and memory. The memory stores one or more programs configured for execution by the one or more processors. The apparatus measures a baseline depth. The apparatus measures a first depth subsequent to measuring the baseline depth. The apparatus determines that the first depth is different from the baseline depth. In response to the determination, the apparatus activates a read cycle. Subsequent to activating the read cycle, the apparatus measures a second depth. The apparatus detects that the second depth is within a threshold range of the baseline depth. In response to the detection, the apparatus deactivates the read cycle.
