This looks interesting, much better than a PIR for motion detection, but of course a camera would be required. Could have some possibilities for EFX and robotics.

    Since this sensor has a 2 bit range ( 0 - 3 ) setting on sensitivity, it may be possible to use it to detect some type of distance also. The sensitivity inputs could be manipulated by the stamp in run time.
    The idea would be to " scan " the sensor on the different sense points in a subroutine, and take the output from each sensitivty mode, and use logic to determine at what range the activation was acquired.
    For example, 0 = low 1 = med low 2= med high 3= high. A scan of the four may only show an output from 0, that would be the closest distance to the cam , or a scan may show an output from 0,1,2 and 3, the farthest distance. A possible mix of outputs from 2 and 3 would closer than 3, but farther than 1. The whole process should not take a lot of time to function, as it is all just pin switching, and the stamp doing the logic. Being a video feed, i am not sure what type of distance ranges could be acquired, probably depends on the quality of the camera itself ( resolution ). Its just theory, not sure if it could work or not.
