One challenge with using sensing devices to collect information about a person is that the person needs to stay within reach of sensor. Several solutions exist to resolve this issue, some relay on improving the machinery of the sensor, while other relay on constraining the movements of the person tracked. Both these methods have limitations. In this invention proposal, we describe a method for improving data collection without restraining the user unnecessary or that require a leap in sensor technology. By providing subtle feedback of the sensor's field of sensitivity in the form of a reflecting UI, the user can adjust his or her position in front of the sensor to improve the data collection.
