SYSTEM AND METHOD FOR CONTROLLING AN ELECTRONIC DEVICE BY HUMAN TREMOR DETECTION
First Claim
1. A method for controlling an electronic device, the method comprising:
- detecting whether the electronic device is physically enclosed in a small space;
detecting whether the electronic device is vibrating at a rate indicative of natural tremors of a human body; and
operating the electronic device in response to whether the electronic device is vibrating at a rate indicative of natural tremors of a human body while the electronic device is not physically enclosed in a small space.

Abstract
An electronic device is operated based on whether it detects vibration indicative of natural human tremors while the device is not enclosed in a small space. Human tremors are detected by sampling a motion signal and performing a discrete Fourier transformation on a plurality of sets of samples. For each sample, a mean magnitude is calculated for a first range of frequencies indicative of human tremors. A mean magnitude is also calculated for a second range of frequencies greater than the first range. If the difference between the mean magnitude of the first range and the mean magnitude of the second range, then human tremors are detected for the set of samples. Human tremors are detected for the device if a threshold number of sets of samples within a predetermined time period produce an output indicating detection.

19. A method for controlling an electronic device, the method comprising:
-
receiving an electronic signal indicative of movement of the electronic device; performing a discrete Fourier transformation on each of a plurality of sets of samples of the signal; for each transformed set of samples, determining a mean value of a magnitude of the signal for a first range of frequencies indicative of natural tremors of a human body; determining a mean value of a magnitude of the signal for a second range of frequencies higher than the first range; and producing an output indicating detection if the difference between the mean value of the magnitude of the first range of frequencies and the mean value of the magnitude of second range of frequencies is greater than a threshold value; and operating the electronic device in response to whether a threshold number of sets of samples within a predetermined time period produce an output indicating detection. - View Dependent Claims (20)
