Portable device for collecting information about living body
View Patent ↗A portable device for collecting information about a human body is adapted to be worn on the human body and is capable of periodically performing cognitive faculty tests during daily life to discern fluctuations in the memory faculty of a wearer. The device displays a problem of cognitive tests on a display unit, and a wearer inputs an answer with an input unit. The wearer's response time is clocked with a clock unit, and the answer and the response time are stored in a memory unit in time sequence by control of a control circuit. The device can include a detection unit for detecting a living body signal to enable research on the relationship between behavioral patterns or temperamental trends and memory faculties, and the like.
1. A portable device for collecting information about a user, comprising: a case mountable on the user's wrist; storage means disposed in the case for storing a plurality of characters; character selection means for selecting a character from the storage means; a display provided on the case for displaying the selected character; input means for allowing user input of information about the character displayed on the display; measuring means disposed in the case for measuring elapsed time from the display of the character until occurrence of the user input; memory means disposed in the case for storing the information input by the user and the time measured by the measuring means; control means for controlling operations of the character selecting means and the memory means control means for controlling operations of the character selecting means and the memory means, the control means having a timer, and, at predetermined time intervals measured by the timer, causing the memory means to store the information input by the user with the input means and the time measured by the measuring means; and delaying means for delaying the start of operation of the memory means to cause the memory means to store the information input by the user with the input means and the time measured by the measuring means at a different time delayed from the predetermined time intervals.
2. A portable device for collecting information about a living body according to claim 1 ; wherein the delaying means includes a switch mounted on the case.
3. A portable device for collecting information about a user according to claim 1 ; wherein the memory means stores the information input by the user with the input means and the time measured by the measuring means for a plurality of sets of sequentially displayed characters that are displayed in time sequence and for a given duration of time.
4. A portable device for collecting information about a user according to claim 1 ; wherein the input means comprises a cursor key mounted on the case.
5. A portable device for collecting information about a user according to claim 1 ; further comprising detection means for detecting bodily movements of the user.
6. A portable device for collecting information about a user according to claim 5 ; wherein the detection means is an acceleration sensor.
7. A portable device for collecting information about a user, comprising: a case mountable on the user's wrist; storage means disposed in the case for storing a plurality of characters; character selection means for sequentially selecting the plurality of characters from the storage means; a display provided on the case for sequentially displaying the selected plurality of characters; input means provided on the case for allowing user input of information about sequentially displayed characters; measuring means disposed in the case for measuring elapsed time from the display of the sequentially displayed characters until occurrence of the user input; memory means disposed in the case for storing the information input by the user and the time measured by the measuring means; control means for controlling operations of the character selecting means and the memory means, the control means having a timer, and, at predetermined time intervals measured by the timer, causing the memory means to store the information input by the user with the input means and the time measured by the measuring means; and delaying means for delaying the start of operation of the memory means to cause the memory means to store the information input by the user with the input means and the time measured by the measuring means at a different time delayed from the predetermined time intervals.
8. A portable device for collecting information about a user according to claim 7 ; wherein the memory means stores the information input by the user with the input means and the time measured by the measuring means for a plurality of sets of sequentially displayed characters that are displayed in time sequence and for a given duration of time.
9. A portable device for collecting information about a user according to claim 7 ; further comprising detection means for detecting bodily movements of the user.
10. A portable device for collecting information about a living body according to claim 7 ; wherein the delaying means includes a switch mounted on the case.
11. A portable device for collecting information about a user, comprising: a case; a timepiece disposed in the case; frontal-lobe-function examining means disposed in the case for executing cognitive ability testing using a display and an input device of the timepiece; and analyzing means for analyzing results of the cognitive faculty tests to determine fluctuations in the user's memory faculty while the user performs different activities.
12. A portable device for collecting information about a user according to claim 11 ; wherein the analyzing means comprises a computer connectable to the portable device.
