| Abstract(in English) | It would be useful in many situations if a person's behavior can be detected by sensors to estimate what the person is interested in. For example, if we can obtain information on places in which persons were particularly interested in some items, it can be useful in designing the placement of items to attract their attention. In this paper, we propose a method to detect trial reading actions of a book. More specifically, the methods detects the actions of "picking up the book from the shelf", "trial reading", and "putting it back on the shelf" from a twist of the person’s list using the time sequence of angular rate sensor data that will be obtained by a smartwatch. We assume that the time length of trial reading actions corresponds to the level of his/her interest in the book. Six participants were asked to perform the trial reading actions in the experiment, and the proposed method achieved a recall rate of detection over 80% and F value over 0.65. In this experiment, we found that the method wrongly estimated in some cases the time at which the action changed from picking up the book to starting trial reading. Similarly, in other cases, it misestimated an action of putting the book back on the shelf to a trial reading action. As our future work, we plan to improve detection accuracy by using an algorithm that does not start detecting trial reading actions during it detects that the person’s arm is raising or lowering judging from an acceleration sensor values. |
