Abstract

PURPOSE:To control the movement direction and movement direction of a cursor extremely easily by using a device which controls the position of the cursor with a voice. CONSTITUTION:A speech recognizing means 101 recognizes a user's voice and a loudness decision means 102 decides the loudness of the user's voice. Then a cursor movement quantity decision means 103 determines the movement quantity of the cursor according to the output of the loudness decision means 102. For example, the cursor is moved by a longer and longer distance as the loudness of the user's voice is larger and larger. Namely, the cursor displayed on an output means 105 is moved according to the output of the speech recognizing means 101 and the output of the cursor movement quantity decision means 103. For example, when 'right' is voiced and the movement distance corresponding to the loudness of the voicing is 10, the cursor is moved right by 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling a cursor position in an apparatus using a cursor such as a personal computer and a word processor.

[0002]

2. Description of the Related Art Conventionally, a voice cursor moving device has been developed for use in a situation where the cursor has to be moved without using a hand and for use by a person with a hand inconvenience. These devices have a configuration as shown in FIG. 5, and when the user utters "right" or the like, the cursor moves in the corresponding direction. For an outline of such a device, see, for example, the 1991 IEICE Spring National Convention A.
-228 Kusura et al. "Cursor-based cursor position control system".

[0003]

However, these systems can be controlled only in the direction in which the cursor is moved. For example, when the user instructs the cursor to move to the right, the cursor moves to the right by a predetermined distance. Therefore, if an instruction to move a long distance is made, the same utterance must be repeated many times and the cursor movement must be repeated, which is very troublesome for the user.

An object of the present invention is to provide a cursor control device which can easily control both the moving direction and the moving distance of a cursor by utterance.

[0005]

A first invention is an apparatus for controlling a cursor position by a voice, wherein a voice recognition means, a volume determination means, and a movement of the cursor based on an output of the volume determination means. Cursor movement amount determining means for determining the amount, cursor movement means for moving the cursor based on the output of the voice recognition means and the output of the cursor movement amount determining means, and the output of the cursor movement means And an output means.

A second aspect of the present invention is a device for controlling a cursor position by voice, which comprises voice recognition means, speech length determination means, and the movement amount of the cursor based on the output of the speech length determination means. From cursor movement amount determination means, cursor movement means for moving the cursor based on the output of the voice recognition means and output of the cursor movement amount determination means, and output means for displaying the output of the cursor movement means. It is characterized by being formed.

[0007]

FIG. 1 is a block diagram showing an embodiment of the first invention. This cursor control device has a voice recognition means 1
01, volume determination means 102, cursor movement amount determination means 103, cursor movement means 104, and output means 10.
It is composed of 5 and. The voice recognition means 101 is a voice input terminal (for example, SR-1 manufactured by NEC Corporation).
50) etc. can be used. A microprocessor or the like can be used as the sound volume determination means 102, the cursor movement amount determination means 103, and the cursor movement means 104. Output means 105
Can use a display, etc.

The operation of controlling the cursor by voice using this cursor control device will be described with reference to the flowchart of FIG. First, the voice recognition unit 101 recognizes the voice uttered by the user (step 301), and the volume determination unit 102 determines the volume of the voice uttered by the user (step 302). The function of determining the volume of voice is described in, for example, the operation manual for the Sony cassette coder TCM-18. Next, the volume determination means 10
Based on the output of 2, the cursor movement amount determination means 103 determines the movement amount of the cursor (step 303). For example, the cursor may be moved a long distance as the volume of the user's voice is high, and the cursor may be moved a short distance as the volume of the user is low. Next, the voice recognition means 101
The cursor displayed on the output means 105 is moved based on the output of the above and the output of the cursor movement amount determination means 103 (step 304). For example, if the utterance is “right” and the movement distance corresponding to the utterance volume is 10, the cursor is moved 10 to the right.

Next, the cursor control device of the second invention will be described. FIG. 3 is a block diagram showing an embodiment of the second invention. In this cursor control device, in the configuration of FIG. 1, the volume determination means 102 is replaced by the utterance length determination means 202.
And the cursor movement amount determination means 103 based on the volume.
Is replaced by the cursor movement amount determination means 203 based on the utterance length. A microprocessor or the like can be used for both the speech length determination means 202 and the cursor movement amount determination means 203.

The operation for realizing cursor control by voice using this cursor control device will be described with reference to the flowchart of FIG. First, the voice recognition unit 101 recognizes the voice uttered by the user (step 301), and the utterance length determination unit 202 determines the length of the utterance uttered by the user (step 402). For the function of determining the speech length of the user, for example, Sony cassette coder TCM-
18 operating instructions. Next, based on the output of the speech length determination means 202, the cursor movement amount determination means 2
03 determines the amount of movement of the cursor (step 40
3). For example, the longer the user's utterance is, the longer the cursor is moved, and the shorter the utterance is, the shorter the cursor is moved. Next, the voice recognition means 10
Based on the output of 1 and the output of the cursor movement amount determination means 103, the cursor displayed on the output means 105 is moved (step 304). For example, if the utterance is "right" and the movement distance corresponding to the length of the utterance is 10, the cursor is moved 10 to the right.

[0011]

By using the cursor control device of the first and second inventions, both the moving direction and the moving distance of the cursor can be easily controlled by voice. Unlike the conventional case, it is not necessary to repeat the same utterance when moving the cursor over a long distance, and the cursor control by voice becomes very easy.
