Input device and information processing apparatus with such input device and cursor display control method
First Claim
1. An input device including a set of cursor-movement keys (or simply cursor keys) that, when activated, cause the cursor to move at an initial speed across the screen in the direction as indicated by the cursor-movement key, a cursor key activation detect means for detecting the activation of any cursor key and outputting the detected result of the cursor key activation for the cursor movement in the direction as indicated, a rotary operation device being operable to be rotated in a clockwise direction and in a counterclockwise direction for performing the input operations through its rotation, a rotary operation device activation detect means for detecting the activation of the rotary operation device and outputting the detect result of the rotation amount or the rotation speed of the rotary operation device and the direction of rotation in which the rotary operation device has been rotated, that is, the clockwise direction or counterclockwise direction representing the forward direction and backward direction respectively, and a cursor movement information generator means for receiving the detect results from the cursor key activation detect means and from the rotary operation device activation detect means, wherein, when the detected result is received only from the cursor key activation detect means, the cursor movement information generator means responds to the received detect result, and provides output signals that cause the cursor to move in the respective direction indicated by the activated cursor key at an initial first speed, and when the detected results are received from both the cursor key activation detect means and the rotary operation activation detect means by the simultaneous operation of the cursor key and the rotary operation device, the cursor movement information generator means responds to the received detected result, and provides output signals such that when the rotary operation device is being rotated in the forward direction the output signals cause the cursor to continue to move in the respective direction indicated by the activated cursor key but at a second speed based upon modulating the first speed according to the rotation amount or the rotation speed of the rotary operation device and when the rotary operation device is rotated in the backward direction the output signals cause the cursor to move in the direction opposite the direction as indicated by the activated cursor key and at said second modulated speed according to the rotation amount or rotation speed of the rotary operation device.

Abstract
An input device may be used with the information processing apparatus and the like, and provides an improved ease of operation in moving the cursor on the display screen.
The input device includes a set of cursor keys 1 that, when activated, cause the cursor to move on a display section 8, a cursor key activation detect means 2, a rotary operation device 3, a rotary operation device activation detect means 4, and a cursor movement information generator means 5 that responds to the detect results from the cursor key activation detect means 2 and from the rotary operation device activation detect means 4, and provides respective output signals that cause the cursor to move as indicated by the received detect results, depending upon whether only the cursor keys are activated or both the cursor keys and the rotary operation device are activated.
Using the input device allows the operator to cause the cursor to move around and across the display screen, quickly and/or with any speed specified by the operator.

6. An information processing apparatus including:
-
(1) the input device having a set of cursor-movement keys (or simply cursor keys) that, when activated, cause the cursor to move across the screen, a cursor key activation detect means for detecting the activation of any cursor key, a rotary operation device being operable to be rotated in the clockwise direction and in the counterclockwise direction and for performing the input operations through its rotation, a rotary operation device activation detect means for detecting the activation of the rotary operation device and outputting the detect result of the rotation amount or the rotation speed of the rotary operation device and the direction of rotation in which the rotary operation device has been rotated, that is, the clockwise direction or counterclockwise direction representing the forward direction and backward direction respectively, and a cursor movement information generator means for receiving the detect results from the cursor key activation detect means and from the rotary operation device activation detect means, wherein, when the detected result is received only from the cursor key activation detect means, the cursor movement information generator means provides output signals that cause the cursor to move in the respective directions as indicated by the activated cursor key, and when the detected results are received from both the cursor key activation detect means and the rotary operation activation detect means by the simultaneous operation of the cursor key and the rotary operation device, the cursor movement information generator means provides output signals that cause the cursor to move in the respective directions as indicated by the activated cursor key when the rotary operation device is rotated in the forward direction, at the movement amount or movement speed as modulated to increase according to the rotation amount or rotation speed of the rotary operation device and provides output signals that cause the cursor to move in the direction opposite the direction as indicated by the activated cursor key at the movement amount or movement speed as modulated to increase according to the rotation amount or rotation speed of the rotary operation device when the rotary operation device is rotated in the backward direction; (2) a display means that displays the cursor on the screen, together with the information such as text, characters, graphical images and the like; and (3) a cursor movement instructing means responsive to the output of the cursor movement information generator means included in the input device for providing instructions to the display means that cause the cursor to move on the screen. - View Dependent Claims (7, 8, 9, 10)

11. A cursor display control method for controlling direction and speed of a cursor displayed on a display screen together with the information such as text characters, graphical images and the like using cursor keys alone or in combination with a rotary operation device comprising the steps of:
- detecting when only the cursor keys are activated to cause the cursor to move at an initial first speed in the respective direction indicated by the activated cursor key and, when it is determined at the detecting step that both the cursor keys and the rotary operation device are simultaneously activated and that the rotary operation device is being rotated in the forward direction causing the cursor to continue to move in the respective direction indicated by the activated cursor key and at a second speed based upon modulating the first speed according to the rotation amount or the rotation speed of the rotary operation device and when the rotary operation device is being rotated in the backward direction moving the cursor in the direction opposite the direction indicated by the activated cursor key and at said second modulated speed according to the rotation amount or rotation speed of the rotary operation device and refreshing the current display as the cursor is moving as instructed.
