Abstract

A motion sensor comprises a touch screen, and a motion indictor proximate to the touch screen, the touch screen displaying: an adjusting bar indicating a threshold at which motion is detected, and a level bar indicating an amount of currently measured motion.

Claims

1. A motion sensor, comprising:

a touch screen; and

a motion indictor proximate to the touch screen, wherein

the touch screen is configured to simultaneously display;

an adjusting bar indicating a threshold at which motion is detected, and

a level bar indicating an amount of currently measured motion, and

the adjusting bar and the level bar are configured to overlap one another.

2. The motion sensor of claim 1, wherein a position of the adjusting bar is adjustable.

3. The motion sensor of claim 2, wherein the position is adjusted by a selection of the adjusting bar and a movement of the adjusting bar up or down.

4. The motion sensor of claim 1, wherein the motion indicator changes color when the adjusting bar indicates detected motion.

5. The motion sensor of claim 1, wherein the motion sensor is an independent element that can be affixed to a wall or other structure.

6. The motion sensor of claim 1, wherein the motion sensor is integrated in a fixed element.

7. The motion sensor of claim 1, wherein the motion sensor is integrated in a mobile element.

8. The motion sensor of claim 1, wherein data from the motion sensor is processed by a calculated statistical mean using a number of samples from the sensor over a time period.

9. The motion sensor of claim 8, wherein a variance is calculated to and/or from the mean to determine a “

spread”

of the data.

10. The motion sensor of claim 9, wherein as each new sample is acquired from the sensor, a new mean and variance are calculated and compared to the threshold at which motion is detected.

11. The motion sensor of claim 10, wherein a variance above the threshold is considered to be motion, whereas a variance below the threshold is considered to noise.

13. The motion sensor of claim 1, wherein the motion sensor is configured to set a sensitivity of the threshold of the adjusting bar and a motion level of the level bar that are displayed to a user based on an empirical determination.

15. The motion sensor of claim 13, wherein the motion sensor is configured to detect when the user'"'"'s hand passes at a distance of one foot from the motion sensor, but does not contact the motion sensor.

12. A method for sensing motion, comprising:

selecting an adjusting bar on a touch screen indicating a threshold at which motion is detected;

moving the selected adjusting bar up or down;

measuring motion by a level bar proximate the adjusting bar;

acquiring the measured motion;

calculating a mean and a variance; and

comparing the calculated mean and variance to the threshold at which motion is detected, wherein

a variance above the threshold is declared as motion, whereas a variance below the threshold is considered noise, and

the adjusting bar and the level bar are configured to be simultaneously displayed and overlap one another.

14. The method of claim 12, further comprising:

setting a sensitivity of the threshold of the adjusting bar and a motion level of the level bar that are displayed to a user based on an empirical determination.

16. The method of claim 14, further comprising detecting when the user'"'"'s hand passes at a distance of one foot from a motion sensor, but does not contact the motion sensor.
