Portable display device, method of controlling portable display device, program, and recording medium
First Claim
1. A portable display device configured to be held by a user, the device comprising:
- a display unit configured to display images respectively in two adjacent screens;
an input unit configured to obtain two or more coordinates of positions on the display unit, the positions being subjected to one of approach, contact, and press by the user; and
a gesture recognizing unit configured to recognize and execute a previously stored processing command corresponding to a changing form of two or more related coordinates by chronologically associating the coordinates of the positions subjected to one of approach, contact, and press on the display unit and obtained by the input unit, whereinthe gesture recognizing unit enters;
a non-accepting state in which recognition and execution of the processing command are unallowed when the coordinates obtained by the input unit do not include a predetermined fixed coordinate, and an accepting state in which recognition of the processing command is allowed when the coordinates obtained by the input unit include the fixed coordinate; and
the input unit obtains, as the fixed coordinate, a predetermined fixed coordinate of a position on the display unit that corresponds to a position of one finger of the user and that corresponds to a position suitable for holding the portable display device by one hand of the user.

Abstract
Provided is a portable display device sufficiently small to be held with one hand that enters a state for accepting a gesture when a fixed coordinate position near a central portion between a left display unit (14a) and a right display unit (14b) is pressed with a thumb Ftl of one hand holding the device, and accepts a command for performing such as page flipping processing based on a gesture inputted with an index finger Ffr of the other hand. Thus, it is possible to achieve an interface for input operations suitable for a two-screen display screen, where holding a two-screen portable display device naturally causes the device to enter a command accepting state to allow gesture recognition, and to enter a command non-accepting state when the portable display device is not held, in order to prevent a command from being falsely executed due to an unintended contact and such to the display screen.

11. A method of controlling a portable display device configured to be held by a user and having a display unit for displaying an image over two adjacent screens, the method comprising:
-
an input step of obtaining two or more coordinates of positions on the display unit, the positions being subjected to one of approach, contact, and press by the user; and a gesture recognizing step of recognizing and executing a previously stored processing command corresponding to a changing form of two or more related coordinates by chronologically associating the coordinates of the positions subjected to one of approach, contact, and press on the display unit and obtained in the input step, wherein the gesture recognizing step is in;
a non-accepting state in which recognition and execution of the processing command are unallowed when the coordinates obtained in the input step do not include a previously determined fixed coordinate of a position on the display unit that corresponds to a position of one finger of the user and that corresponds to a position suitable for holding the portable display device by one hand of the user, and an accepting state in which recognition of the processing command is allowed when the coordinates obtained in the input step include the fixed coordinate.

12. A computer-readable non-transitory recording medium having a program recorded therein, the program causing a portable display device having a display unit for displaying an image over two adjacent screens and configured to be held by a user to execute:
-
an input step of obtaining two or more coordinates of positions on the display unit, the positions being subjected to one of approach, contact, and press by the user; and a gesture recognizing step of recognizing and executing a previously stored processing command corresponding to a changing form of two or more related coordinates by chronologically associating the coordinates of the positions subjected to one of approach, contact, and press on the display unit and obtained in the input step, wherein the gesture recognizing step is in;
a non-accepting state in which recognition and execution of the processing command are unallowed when the coordinates obtained in the input step do not include a previously determined fixed coordinate of a position on the display unit that corresponds to a position of one finger of the user and that corresponds to a position suitable for holding the portable display device by one hand of the user, and an accepting state in which recognition of the processing command is allowed when the coordinates obtained in the input step include the fixed coordinate.
