Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling a presentation program which enables a presenter (user) to control a presentation program only by operating a control device connected to an information processing prime such as a personal computer. It relates to the device and the recording medium.

[0002]

2. Description of the Related Art In place of a conventional slide projector, a presentation environment using an information processing device such as a personal computer and a projector has become widespread. As a presentation application that operates on the information processing apparatus, for example, Microsoft PowerPoint (trademark) is used.

[0003] The above-described application has a slide operation function in addition to a material creation function, and presents pre-ordered slides in order according to a user's instruction, or displays a specific slide. It has a function to present.

[0004] A slide operation instruction is usually issued using a pointing device connected to the information processing apparatus or a pointing device built in the information processing apparatus. For example, in the PowerPoint shown as an example,
Click the left mouse button or press the N key to advance to the next slide. When the menu is presented with the right button, the previous slide item is selected, or the P key is pressed, the display returns to the previous slide.

When moving to a specific slide, a menu is presented by a right button, a slide moving item is selected,
Alternatively, by pressing the G key, a slide moving item is selected, a slide selection window is displayed, and a specific slide is presented on the screen by clicking a target slide or selecting an item by a key operation.

[0006] In presentations, eye contact with the audience is important. Also, performing an action unrelated to the content of the story distracts the audience and is not desirable. Therefore, if the purpose is to operate an electronic presentation, an interface that does not hinder the presenter's action or that does not hinder the presenter is required.

At present, it is common to perform slide control of a presentation using a pointing device such as a mouse. The command to move the slide back and forth can be realized by a simple operation of clicking a mouse button, so that the presenter can give a presentation without distracting the audience. However, when moving to an arbitrary slide during a question-and-answer session or when displaying another presentation file, the presenter needs to pay attention to the operation of selecting a desired target such as a slide or a file.

Although a method of performing slide control by utterance using voice recognition has been proposed, problems remain in moving to an arbitrary slide, selecting a file, and the like. For example, if the slide with the title of the conventional problem is the eighth slide, it is necessary to utter like “slide 8”,
It is necessary to store the correspondence between the slide content and the slide number in advance. Alternatively, it is necessary to prepare a correspondence table between “conventional tasks” and “slide 8”.

As a coping method, Japanese Patent Application Laid-Open No. 8-339198 proposes a patent which analyzes a file and extracts a keyword. However, the structure is such that a file is analyzed and a slide title itself is registered in a dictionary. The user is required to utter the title accurately, which limits the usability.

[0010]

As described above, conventionally,
To navigate between slides and select files,
Users were required to focus their attention on the operation.

[0011] Therefore, there is a problem that eye contact with the audience cannot be continued due to the operation of directing the line of sight to the screen, and that the attention of the audience deviates from the presentation due to the operation.

When using voice recognition, the user needs to prepare for the voice recognition.

The present invention provides a presentation program control method, apparatus, and recording medium that enable easy operation without distracting the listener.
