Abstract
Official abstract text for this publication.
An information processing apparatus includes an acquisition unit configured to acquire information based on a sensor attached to a foot of a user, a determination unit configured to make a decision about an abnormality in walking of the user based on an acceleration of the user in a walking direction, acquired by the acquisition unit, and an output unit configured to output information based on a result of the decision made by the determination unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . An information processing apparatus comprising: an acquisition unit configured to acquire information based on a sensor attached to a foot of a user; a determination unit configured to make a decision about an abnormality in walking of the user based on an acceleration of the user in a walking direction, acquired by the acquisition unit; and an output unit configured to output information based on a result of the decision made by the determination unit. 2 . The information processing apparatus according to claim 1 , wherein the acquisition unit acquires information based on a sensor attached at a position located between an arch of the user's foot and a heel thereof. 3 . The information processing apparatus according to claim 1 , wherein the determination unit makes a decision about an abnormality in walking of the user based on at least one of a first acceleration in the walking direction that occurs when a toe of the foot comes off a ground surface, a second acceleration in the walking direction that occurs when the foot is swung in the walking direction by contraction of a thigh muscle of the user, and a walking speed of the user. 4 . The information processing apparatus according to claim 1 , wherein the determination unit makes a decision about an abnormality in walking of the user based on at least one of a third acceleration in the walking direction that occurs when the foot lands on a ground surface, a second acceleration in the walking direction that occurs when the foot is swung in the walking direction by contraction of a thigh muscle of the user, and a walking speed of the user. 5 . The information processing apparatus according to claim 1 , wherein the determination unit makes a decision about an abnormality in walking of the user based on a magnitude of a one-vibration component of an acceleration of the user in the walking direction during a period in which the user makes one step. 6 . The information processing apparatus according to claim 1 , wherein the determination unit makes a decision about an abnormality in walking of the user based on at least one of an angle between a sole of the foot and a ground surface in the walking direction during a period in which the user makes one step, and a magnitude of a five-vibration component of an acceleration of the user in a vertical direction during the period in which the user makes one step. 7 . An information processing method comprising: acquiring information based on a sensor attached to a foot of a user; making a decision about an abnormality in walking of the user based on an acquired acceleration of the user in a walking direction; and outputting information based on a result of the decision. 8 . An information processing system comprising a sensor attached to a foot of a user, an information processing apparatus, and an information processing terminal, wherein the information processing system comprises: an acquisition unit configured to acquire information based on an acceleration of the user in a walking direction, measured by the sensor; a determination unit configured to make a decision about an abnormality in walking of the user based on an acceleration of the user in a walking direction, acquired by the acquisition unit; and an output unit configured to make the information processing terminal output information based on a result of the decision made by the determination unit.
