A measurement system includes a six-axis force sensor provided in a wheelchair, a rotation angle recognition part which recognizes a rotation angle of the six-axis force sensor, and a COP estimation part which estimates a COP that is the applied position of the driving force from the occupant to the wheelchair. The COP estimation part estimates the COP based on a translational force and a moment detected by the six-axis force sensor and based on the rotation angle recognized by the rotation angle recognition part to improve estimation accuracy of the COP estimation part and measurement accuracy of the measurement system.

A content providing device, a content providing method, and a storage medium which allows a user to ascertain a state of a tourist spot on the day of travel are provided. A content providing device includes a first acquirer configured to acquire a travel plan that includes at least a scheduled visit date and a scheduled location to be visited of a user, a second acquirer configured to acquire content that indicates a state of a scheduled location to be visited scheduled or estimated on the scheduled visit date of the user according to an image on the basis of the travel plan, and a reproduction controller configured to cause a reproduction device to reproduce the content.

Content providing device, content providing method, and storage medium

A motion assist device, comprises a brace () configured to be worn by a user, an assist motor () provided in association with the brace to assist a prescribed motion of the user, a control unit () for controlling an operation of the assist motor, and an attitude detection sensor () connected to the control unit for detecting an attitude of the user. The control unit is configured to activate the assist motor when a prescribed attitude of the user is detected by the attitude detection sensor so that loads on parts of the user's body other than the part which is directly assisted can be minimized.

Provided are a walking state estimating device and a walking state estimating method. A reference point Q (m) is defined at the bottom end portion of one of the pair of legs of a subject P, the one leg being estimated to be in a stance leg state, i.e. the one leg that is highly likely to be the supporting leg when the subject P changes the position and attitude of his/her torso. Hence, when the reference point Q (m) is changed, the position of the current reference point Q (m) can be estimated with high accuracy on the basis of the position of a previous reference point Q (m&#x2212;1) before the change and according to the attitudes of the torso and the one leg at the time point at which the current reference point is defined after the change.

Walking state estimating device and walking state estimating method

Provided is a walking assist device independent of a deviation of a bending/stretching state between user's legs and applying a force to a user in a direction intended by the user. The walking assist device performs control so that the larger the deviation of a value of a bending/stretching state variable representing the bending/stretching state of each of a pair of right and left legs of a user P is, the larger the deviation between the assist forces Fr and Fl acting on the user P from each of the leg linksis.

An upper body motion measurement systemhas a plurality of inertia sensor units, each of which incorporating an angular velocity sensorand an acceleration sensor. The plurality of the inertia sensor unitsis attached to places that are different from each other on the upper body of a subject P. Based on the detection outputs of the angular velocity sensorand the acceleration sensor, the attitude of each of the inertia sensor unitsis estimated, and the acceleration thereof is further estimated.

Second joints are provided in positions where a seating unit is restrained from swinging relative to leg links due to a force acting on the seating unit from upper limb links through the intermediary of the second joints. A motion not intended by a user can be restrained from being generated due to a force acting from the upper limb links provided in the upper limbs.

In the walking assist device, defining rigidity of a portion from the user to a first joint as K1 [N/m], rigidity of a portion from the first joint to the second joint as K2 [N/m] and rigidity of a portion from the second joint to one of the feet of a free leg of the user as K31 [N/m], when the user is supported by the support member, they are set as: (K1 +K31)&#x3c;K2. With this, the assist force can avoid being affected by, in the direction of gravity, vertical displacement of a portion other than the main body of the device and the control accuracy of the assist force is enhanced accordingly, thereby improving the assisting feel sensed by the user P.
