Recall device

Abstract

A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.

Description

technical field [0001] The present invention relates generally to electronic devices, and more particularly to recall devices. Background technique [0002] The ability to retrieve events, personal parameters, and environmental parameters experienced by an individual is found in many applications. For example, a person with impaired memory, such as a person with Alzheimer's disease, and his or her caregiver may resume some of the individual's daily activities to help fill in the gaps in the individual's memory (such as determining where the individual left the house keys, or identifying who the individual communicates with, etc.). In another application, events and parameters associated with a traumatic event, such as an injury in an elderly person caused by a fall, can be recovered by a physician in order to better understand the cause and extent of the injury. Likewise, retrieval of events and parameters experienced by a child throughout the day can help a parent or teac...
