first embodiment

FIG. 1 is a block diagram showing the hardware arrangement of a portable terminal device according to the first embodiment.

Reference numeral 201 denotes a CPU for controlling various building elements of the portable terminal device; 202, a jog dial switch used to operate the display window of a display 207; 203, a jog dial controller for controlling the operation of the jog dial switch; and 204, a RAM functioning as the work areas of various processes and a temporary data save area. The RAM 204 (FIG. 2) has a operation table memory area for storing a jog dial operation table for managing the operation of the jog dial switch 202 of the portable terminal device and an operation of the display window corresponding to this operation, and a VRAM data creation area for creating data for the display window.

Reference numeral 205 denotes a display memory (VRAM) for storing display data to be displayed on the display 207; and 206, a display controller for controlling display of display d...

second embodiment

Although rotation operation of the jog dial switch scrolls the display window in the first embodiment, rotation operation maybe associated with another operation. In the second embodiment, rotation operation of the jog dial switch is made to correspond to operation of moving the focus when a plurality of focusing targets are displayed.

A repetitive description to the first embodiment will be omitted.

FIG. 6 is a view showing the schematic appearance of a portable terminal device according to the second embodiment.

As shown in FIG. 6, a vertically elongated screen 4000 displays the push buttons of a telephone set.

On the vertically elongated screen 4000, a button “1” is focused. The focus on the button can be sequentially switched by rotating a jog dial switch 406.

A jog dial operation switch in the second embodiment will be described with reference to FIG. 6.

The jog dial operation switch in the second embodiment is a table for managing control information for the operation of...

third embodiment

In the first and second embodiments, if the display direction is changed, the operating direction of the jog dial switch is automatically changed. Alternatively, the user may arbitrarily designate this operating direction. The operating direction is designated by, e.g., pushing the jog dial switch. Processing in this case will be explained with reference to FIG. 7.

FIG. 7 is a flow chart showing processing executed in the third embodiment.

The same step numbers as in the first embodiment denote the same steps, and a description thereof will be omitted.

If a display direction change icon 405 is determined in step S107 to be tapped, whether a jog dial switch 406 has been pushed is checked (step S601). If the jog dial switch 406 has not been pushed (NO in step S601), the flow shifts to step S108. If the jog dial switch 406 has been pushed (YES in step S601), the flow shifts to step S602 to change the display window without changing control information of the jog dial operation table...

Abstract

A RAM stores a management table for making the indication state of an indicator in the display direction correspond to control information for controlling the operation an information processing apparatus for the indication state. A CPU detects the indication state of the indicator, and controls the operation of the information processing apparatus on the basis of control information of the management table corresponding to the detection result.

Description

FIELD OF THE INVENTION The present invention relates to an information processing apparatus having an indicator, a control method therefor, and a computer readable memory. BACKGROUND OF THE INVENTION In many cases, a portable terminal device having a jog dial switch or shuttle switch is operated by a different method from that of a so-called desktop terminal device. The desktop terminal device mainly uses a keyboard or mouse as an input device, whereas the portable terminal device is operated by a pen input or button input. In recent years, input devices such as a shuttle switch and jog dial switch for enabling rotation operation and push operation with one device are becoming available. The input devices such as a shuttle switch and jog dial switch are used for operations such as switching of the menu and scroll of the display window. This provides the user with high operability because rotation operation or slide operation directly and readily links with an operation on the dis...
