Abstract

Motion detection notification is described. In an embodiment, a motion detector in a portable device detects a motion of the device and issues an activation signal when the detected motion has a magnitude greater than a preset threshold. A detection notification component in the portable device then receives the activation signal and initiates communication with an additional device that detects a corresponding motion to the motion of the portable device and is configured for communication with the portable device.

Claims

1. A computing-based device, comprising:

a motion detector configured to;

detect a first motion of the computing-based device and issue a first activation signal when the first motion has a magnitude greater than a preset threshold; and

detect a second motion of the computing-based device and issue a second activation signal when the second motion has a magnitude greater than the preset threshold; and

a detection notification component configured to;

receive the first activation signal and the second activation signal;

initiate communication with an additional computing-based device that detects motions corresponding to the first motion and the second motion of the computing-based device, the additional computing based device being configured for communication with the computing-based device;

determine a time duration between the first activation signal and the second activation signal; and

use the time duration to create an encryption key to enable secure communication with the additional computing-based device.

2. A computing-based device of claim 1, wherein the motion detector is further configured to detect the first and second motions as bump contacts between the computing-based device and the additional computing-based device.

3. A computing-based device of claim 1, further comprising a processor configured to activate after the first motion is detected, the processor further configured to execute the detection notification component to initiate the communication with the additional computing-based device.

4. A computing-based device of claim 1, wherein the first activation signal and second activation signal are non-consecutive activation signals.

5. A computing-based device of claim 1, further comprising a timer from which the detection notification component determines the time duration, and wherein the motion detector is an accelerometer.

6. One or more computer-readable media comprising computer executable instructions that, when executed, direct a computing-based device to:

detect a motion of the computing-based device;

generate a credential that corresponds to the motion being detected when the motion exceeds a threshold value;

initiate communication with an additional device having an associated credential; and

communicate the credential to the additional device such that the additional device can compare the credential to the associated credential to form a basis for communication between the additional device and the computing-based device.

7. One or more computer-readable media of claim 6, further comprising computer executable instructions that, when executed, direct the computing-based device to at least one of register a direction of the motion of the computing-based device when the motion is detected, register a velocity of the motion of the computing-based device when the motion is detected, or register a time associated with the motion of the computing-based device.

8. One or more computer-readable media of claim 7 further comprising computer executable instructions that, when executed, direct the computing-based device to generate the credential based on at least one of the direction of the motion, the velocity of the motion, or the time associated with the motion.

9. One or more computer-readable media of claim 6, further comprising computer executable instructions that, when executed, direct the computing-based device to generate the credential to form a basis for encrypted communication with the computing-based device.

10. One or more computer-readable media of claim 6, further comprising computer executable instructions that, when executed, direct the computing-based device to restrict the communication with the additional device to a selectable type of information.

11. One or more computer-readable media of claim 6, further comprising computer executable instructions that, when executed, direct the computing-based device to:

detect the motion of the computing-based device as a bump contact between the computing-based device and the additional device;

generate the credential based on one or more characteristics associated with the bump contact being detected when the bump contact exceeds the threshold value; and

generate an encryption key from the credential to enable secure communications between the computing-based device and an additional device.
