Abstract

An information processing apparatus includes circuitry to receive contact event information indicating that an electronic pen comes into contact with a screen, move event information indicating that the electronic pen moves in a state of being in contact with the screen, separation event information indicating that the electronic pen detaches from the screen, and button pressing information indicating that a button of the electronic pen is pressed, and invalidate an instruction according to the button pressing information during a writing operation period from a start of a writing operation using the electronic pen to an end of the writing operation. The start of the writing operation is determined based on a time when the move event information is received, and the end of the writing operation is determined based on a time when the separation event information is received.

First claim

The invention claimed is:

1 . An information processing apparatus comprising circuitry configured to:
receive contact event information indicating that an electronic pen comes into contact with a screen, move event information indicating that the electronic pen moves in a state of being in contact with the screen, separation event information indicating that the electronic pen detaches from the screen, and button pressing information indicating that a button of the electronic pen is pressed, the electronic pen configured to operate in an operation mode including a first mode or a second mode; switch between the first mode and the second mode by pressing or releasing the button of the electronic pen; in response to receiving the contact event information, determine whether the operation mode of the electronic pen is the first mode or the second mode; start the determined operation mode; and in response to receiving the move event information after the operation mode is started, execute a writing operation using the electronic pen, and maintain the operation mode regardless of pressing or releasing the button of the electronic pen during the writing operation, until receiving the separation event information.

2 . The information processing apparatus according to claim 1 , wherein the circuitry is further configured to, in a case in which the contact event information is received within a certain period of time after the separation event information is received during the writing operation, ignore the separation event information and the contact event information, and continue the writing operation.

3 . The information processing apparatus according to claim 1 , further comprising:
a contact sensor configured to detect the electronic pen, wherein the button of the electronic pen has at least one of a function equivalent to a right click of a mouse or a function of selecting an item, and the electronic pen further has an indicator indicating a state of the writing operation using the electronic pen.

4 . The information processing apparatus according to claim 1 , wherein the circuitry is further configured to, during the writing operation, display a display screen that presents information indicating that the writing operation using the electronic pen is in progress.

5 . An information processing system comprising circuitry configured to:
receive contact event information indicating that an electronic pen comes into contact with a screen, move event information indicating that the electronic pen moves in a state of being in contact with the screen, separation event information indicating that the electronic pen detaches from the screen, and button pressing information indicating that a button of the electronic pen is pressed, the electronic pen configured to operate in an operation mode including a first mode or a second mode; switch between the first mode and the second mode by pressing or releasing the button of the electronic pen; in response to receiving the contact event information, determine whether the operation mode of the electronic pen is the first mode or the second mode; start the determined operation mode; and in response to receiving the move event information after the operation mode is started, execute a writing operation using the electronic pen, and maintain the operation mode regardless of pressing or releasing the button of the electronic pen during the writing operation, until receiving the separation event information.

6 . The information processing system of claim 5 , further comprising the electronic pen.

7 . An information processing method, comprising:
receiving contact event information indicating that an electronic pen comes into contact with a screen, move event information indicating that the electronic pen moves in a state of being in contact with the screen, separation event information indicating that the electronic pen detaches from the screen, and button pressing information indicating that a button of the electronic pen is pressed, the electronic pen configured to operate in an operation mode including a first mode or a second mode; switching between the first mode and the second mode by pressing or releasing the button of the electronic pen; in response to receiving the contact event information, determining whether the operation mode of the electronic pen is the first mode or the second mode; starting the determined operation mode; and in response to receiving the move event information after the operation mode is started, executing a writing operation using the electronic pen, and maintaining the operation mode regardless of pressing or releasing the button of the electronic pen during the writing operation, until receiving the separation event information.

8 . A non-transitory recording medium storing a plurality of program codes which, when executed by one or more processors, causes the one or more processors to perform the method according to claim 7 .
