Brief Patent Description - Full Patent Description - Patent Application Claims
The present invention contains subject matter related to Japanese Patent Application JP2007-330849 filed in the Japanese Patent Office on Dec. 21, 2007, the entire contents of which being incorporated herein by reference. 1. Field of the Invention The present invention relates to an information processing device and a touch operation detection method, which are suitably applied to, e.g., a portable navigation device. 2. Description of the Related Art A portable navigation device (hereinafter, referred to as “PND”) is designed to be detachably attached to the dashboard of a vehicle via a cradle. The PND of such a type serves as a vehicle navigation device when being attached to the dashboard via a cradle and serves as a personal navigation device when being detached from the dashboard. This type of PND aims more for portability than remote-controllability. Thus, a remote controller is not provided for the PND but a user interface that receives a command from a user via a touch panel provided on the front surface of a liquid crystal display is adopted. There is also known an electric book display control device equipped with a display integrated tablet on which a user uses his or her finger to perform a pointing operation to realize a page-turning operation (refer to, e.g., Jpn. Pat. Appln. Laid-Open Publication No. 2004-348755). The PND having such a configuration displays a plurality of destination candidates so as to allow a user to select his or her destination. If the destination candidates exist over a plurality of pages, the user needs to perform a page-turning operation in order to determine the destination. In such a case, where the PND performs a page-turning operation in response to the user\'s pointing operation using his or her finger in the same manner as in the case of the abovementioned electronic book display control device, the PND often erroneously detects that a depression operation with respect to the candidate destination has been made at the moment when the user falsely touched one of the destination candidates with his or her finger, not a page-turning button. Thus, there is a possibility that the PND cannot correctly reflect the user\'s intention to perform a pointing operation. The present invention has been made in view of the above points and an object thereof is to propose an information processing device and a touch operation detection method capable of correctly detect a command issued in response to a user\'s touch operation. To solve the above problem, according to an aspect of the present invention, there is provided an information processing device including: a display unit having a touch panel on its front surface; a movement amount calculation unit for calculating a movement amount of a touch operation based on a touch point at which the touch operation is performed with respect to the touch panel and a touch release point at which the touch operation is released from the touch panel; an operation determination unit for determining whether the touch operation is a depression operation or a gesture operation depending on the calculated movement amount; and a command recognition unit for recognizing whether a received command is a command corresponding to the depression operation or the gesture operation. With the above configuration, the information processing device determines whether a touch operation is a button touch operation or a gesture operation depending on the movement amount of the touch operation, thereby correctly recognizing whether a received command is a command corresponding to the depression operation or the gesture operation. According to another aspect of the present invention, there is provided a touch operation detection method including: a touch point detection step in which a touch point detection unit detects a touch point at which a touch operation is performed with respect to a touch panel provided on the front surface of a display unit; a touch release point detection step following the touch point detection step, in which a touch release point detection unit detects a touch release point at which the touch operation is released from the touch panel; a movement amount calculation step in which a movement amount calculation unit calculates a movement amount of the touch operation based on the touch point and touch release point; an operation determination step in which an operation determination unit determines whether the touch operation is a depression operation or a gesture operation depending on the calculated movement amount; and a command recognition step in which a command recognition unit recognizes whether a received command is a command corresponding to the depression operation or the gesture operation. With the above configuration, the touch operation detection method determines whether a touch operation is a button touch operation or a gesture operation depending on the movement amount of the touch operation, thereby correctly recognizing whether a received command is a command corresponding to the depression operation or the gesture operation. According to the present invention, whether a touch operation is a button touch operation or a gesture operation is determined depending on the movement amount of the touch operation, allowing correct determination on whether a received command is a command corresponding to the depression operation or the gesture operation. Therefore, an information processing device and a touch operation detection method capable of correctly recognizing a command corresponding to a user\'s touch operation can be realized. The nature, principle and utility of the invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings in which like parts are designated by like reference numerals or characters.
