A data browse apparatus acquires a direction indicated by data 1311, 1312 expressing a path of a target. It then acquires an instruction direction 1320 which may be the direction of movement of a camera or a direction indicated by a users interaction with a touch screen display. A relationship is then determined between the data direction and the instruction direction by, for example, calculating the inner product of the two vectors. A display control means then highlights the data direction from among a plurality of data trajectories based on the determined relationship. For example, data directions which are similar to the instruction direction may be highlighted by changing their style or colour. This allows easier following or tracking of specific targets among a plurality of targets. The data direction may be distinguished based on whether the correlation between the data and the instruction direction is above a threshold value. |
