Abstract

According to one embodiment, an information processing apparatus includes: a calculator configured to calculate a screen operation position on a screen irregularly in accordance with a touch operation position on a touch device; a second calculator configured to calculate a predicted screen operation position on the screen based on the screen operation position at a calculation interval shorter than an update interval at which a display content on the screen is updated; and a generator configured to generate image data to be displayed on the screen based on the predicted screen operation position.

Claims

1. An information processing apparatus comprising:

a calculator configured to calculate a screen operation position on a screen irregularly in accordance with a touch operation position on a touch device;

a second calculator configured to calculate a predicted screen operation position on the screen based on the screen operation position at a calculation interval shorter than an update interval at which a display content on the screen is updated; and

a generator configured to generate image data to be displayed on the screen based on the predicted screen operation position.

2. The information processing apparatus of claim 1, wherein the calculation interval is substantially half the update interval.

3. The information processing apparatus of claim 1, wherein the second calculator is configured to calculate a movement speed of the screen operation position based on the screen operation position, calculate the predicted screen operation position when the screen operation position is moved at the movement speed, and correct the movement speed in accordance with a difference between the screen operation position and the predicted screen operation position.

4. The information processing apparatus of claim 3, wherein the second calculator is configured to correct the movement speed such that the difference between the screen operation position and the predicted operation position is decreased in a stepwise manner every time the image data is generated.

5. A display control method performed with an information processing apparatus, the display control method comprising:

calculating, by a calculator in the information processing apparatus, a screen operation position on a screen irregularly in accordance with a touch operation position on a touch device;

second calculating, by a second calculator in the information processing apparatus, a predicted screen operation position on the screen based on the screen operation position at a calculation interval shorter than an update interval at which a display content on the screen is updated; and

generating, by a generator in the information processing apparatus, image data to be displayed on the screen based on the predicted screen operation position.
