According to one embodiment, a time series information acquisition unit acquires time series information of a position or a size of a specific part of a user's body. An operation segment detection unit detects a movement direction of the specific part from the time series information, and detects a plurality of operation segments each segmented by two of a start point, a turning point and an end point of the movement direction. A recognition unit specifies a first operation segment to be recognized and a second operation segment following the first operation segment among the plurality of operation segments, and recognizes a motion of the specific part in the first operation segment by using a first feature extracted from the time series information of the first operation segment and a second feature extracted from the time series information of the second operation segment.

According to one embodiment, an information search apparatus includes a generation unit, a selection unit, a search unit and a display unit. The generation unit generates recognition candidate character strings based on shapes of strokes and combinations of the shapes. The selection unit calculates reliability values for the recognition candidate character strings and selects search keys from the recognition candidate character strings. The search unit searches a database for second character strings including the search keys, and obtains one or more result character strings indicating search results of each of the search keys. The display displays the one or more result character strings corresponding to each of the search keys distinctively.

In an embodiment, a recognition apparatus includes an obtaining unit, a calculating unit, a principal axis selecting unit, a turning point setting unit, a section setting unit, and a determining unit. The obtaining unit obtains positions of a specific part in a coordinate system having a first axis to an n-th axis (n≧2). The calculating unit calculates a movement vector of the specific part. The principal axis selecting unit selects a principal axis. The turning point setting unit sets a position at which there is a change in the principal axis and sets a position at which there is a change. The section setting unit sets a determination target section, and sets a previous section. The determining unit calculates an evaluation value of the determination target section and an evaluation value of the immediately previous section and determines which of the first axis to the n-th axis is advantageous.

According to an embodiment, a tracking device includes an acquiring unit, a first calculator, a second calculator, and a setting unit. The acquiring unit images a tracking target object to time-sequentially acquire an image. The first calculator calculates a first likelihood representing a degree of coincidence between a pixel value of each pixel included in a search region within the image and a reference value. The second calculator calculates a difference value between the pixel value of each pixel in the search region and the pixel value of a corresponding pixel in an image in a past frame. The setting unit sets weights of the first likelihood and the difference value so that as a distance between each pixel in the search region and a position of the tracking target object in the past increases, the weight of the first likelihood decreases and the weight of the difference value increases.
