Information processing apparatus, information processing method, and information providing medium

An information processing apparatus comprising:

• operating means for operating a jog-capable application by having a first operating block corresponding to a rotational operation and a second operating block corresponding to a depressing operation, and for generating left and right detection signals that are supplied to left and right signal counters, respectively;
• and
• control means for monitoring an operating state of the operating means and for monitoring a rotational distance of said rotational operation by polling the amount of change that occurs in the left and right signal counters,
• whereby a list of jog-capable applications is activated by the depressing operation,
• whereby a jog-capable application is selected from the list of jog-capable applications by the rotational operation,
• whereby the selected jog-capable application is enabled by the depressing operation,
• whereby after a jog-capable application is enabled, a list of jog-capable application operations is activated,
• whereby a jog-capable application operation is selected from the list of jog-capable application operations by the rotational operation, and
• whereby the selected jog-capable application operation is executed by the depressing operation.

An information processing method comprising the steps of:

• depressing step for activating, enabling and executing jog-capable applications;
• rotating step for selecting a jog-capable application from a plurality of jog-capable applications and for selecting a jog-capable application operation from a plurality of jog-capable application operations;
• generating step for generating left and right detection signals that are supplied to left and right signal counters, respectively;
• and
• monitoring step for monitoring a rotational distance of said rotational step by polling the amount of change that occurs in the left and right signal counters,
• whereby a list of jog-capable applications is activated by the depressing step
• whereby a jog-capable application is selected from the list of jog-capable applications by the rotating step,
• whereby the selected jog-capable application is enabled by the depressing step,
• whereby after a jog-capable application is enabled, a list of jog-capable application operations is activated,
• whereby a jog-capable application operation is selected from the list of jog-capable application operations by the rotating step, and
• whereby the selected jog-capable application operation is executed by the depressing step.

An information processing method comprising the steps of:

• operating a jog-capable application by having a first operating block corresponding to a rotational operation and a second operating block corresponding to a depressing operation;
• generating left and right detection signals that are supplied to left and right signal counters, respectively;
• monitoring an operating state of the operating means;
• and
• monitoring a rotational distance of said rotational operation by polling the amount of change that occurs in the left and right signal counters,
• whereby a list of jog-capable applications is activated by the depressing operation,
• whereby a jog-capable application is selected from the list of jog-capable applications by the rotational operation,
• whereby the selected jog-capable application is enabled by the depressing operation,
• whereby after a jog-capable application is enabled, a list of jog-capable application operations is activated,
• whereby a jog-capable application operation is selected from the list of jog-capable application operations by the rotational operation, and
• whereby the selected jog-capable application operation is executed by the depressing operation.

An information providing medium for making an information processing apparatus execute a computer program by depressing and rotating a jog dial,

• whereby said jog dial generates left and right detection signals which are supplied to left and right signal counters, respectively,
• whereby said information processing apparatus monitors a rotational distance of said jog dial by polling the amount of change that occurs in the left and right signal counters,
• whereby a jog dial menu containing a list of jog-capable applications is activated by depressing the jog dial, a jog-capable application is selected from the jog dial menu by rotating the jog dial, and the selected jog-capable application is enabled by depressing the jog dial, and
• whereby after a jog-capable application is selected, a jog dial operation menu containing operations of the selected jog-capable application is activated by depressing the jog dial, an operation from the jog dial operation menu is selected by rotating the jog dial, and the selected operation is executed by depressing the jog dial.

An information providing medium for making an information processing apparatus execute a computer program having a first operating block corresponding to a rotational operation and a second operating block corresponding to a depressing operation and monitoring an operating state of the rotational operation and the depressing operation,

• whereby said rotational operation generates left and right detection signals which are supplied to left and right signal counters, respectively,
• whereby said information processing apparatus monitors a rotational distance of said rotational operation by polling the amount of change that occurs in the left and right signal counters,
• whereby a jog dial menu containing a list of jog-capable applications is activated by the depressing operation, a jog-capable application is selected from the jog dial menu by the rotational operation, and the selected jog-capable application is enabled by the depressing operation, and
• whereby after a jog-capable application is selected, a jog dial operation menu containing operations of the selected jog-capable application is activated by the depressing operation, an operation from the jog dial operation menu is selected by the rotational operation, and the selected operation is executed by the depressing operation.
