Abstract: 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.

Abstract: A portable living body information collection device is arranged to continuously measure living body information in daily life and to efficiently collect relating mental information by timely questioning about health. The device can be worn on a human body. The portable living body information collection device extracts living body information in electrical signal form by a detection circuit and a signal processing circuit, and discretizes the information by a conversion circuit. A control circuit stores the discretized living body information in a storage and displays questions about feelings and mental conditions on a display unit periodically or when a large changes occurs in living body information. The wearer inputs answers by using an input device, and the answers are also recorded as mental information in the storage.

Abstract: A portable device for collecting information about a living body is provided, which can be worn on the human body and is capable of periodically performing cognitive faculty tests during daily life to grasp fluctuations in the memory faculty of a wearer. The device includes: a character selection unit for randomly selecting plural kinds of characters; a display portion for displaying the characters; an input unit for answering about the relationship between characters displayed randomly in the display portion in adjoining time sequence; a clocking unit for clocking a response time from when the displayed character is updated, until the input signal is inputted from the input unit; a memory unit for storing the answer from the input unit, and the response time; and a control circuit for causing the memory unit to store the response time and the answer, in time sequence.
