Abstract

The invention provides an interface system using mastication myoelectricity. The interface system enabling quick menu selection without special mastication or repetition of highlight even in any situation that myoelectricity is produced during e.g., conversation or a meal in the daily life of the user. The interface system includes an output unit for visually presenting an operation menu of a device, a measuring unit for measuring the mastication myoelectricity of the user, a menu presenting unit for sequentially presenting each of the menu items contained in the operation menu through the output unit, an amplitude calculating unit for determining the maximum amplitude of the potential waveform of the mastication myoelectricity, a latent time calculating unit for determining the latent time at which the potential waveform takes on a maximum amplitude from when each of the menu items is highlighted, and a judging unit for judging whether or not the maximum amplitude is larger than a predetermined threshold and whether or not the latent time is within a range of about 200 ms after the highlight. The menu presenting unit executes the processing corresponding to the highlighted menu item depending on the result of the judgment made by the judging unit.

Description

technical field

[0001] The invention relates to an interface system for machines. More specifically, the present invention relates to an interface system for a device that utilizes user's biological information (myoelectricity that can be measured around the head). Background technique

[0002] In recent years, various information devices such as TVs, mobile phones, and head mount displays (HMD: Head Mount Displays) have become popular and entered daily life. Therefore, users often need to operate information devices in their daily life.

[0003] Usually, the user inputs commands by hand through an input mechanism (interface part) such as a key, so as to realize the operation of the machine. However, when performing housework, childcare, or driving, for example, both hands are occupied by things other than machine operation. In such a situation, it is difficult to operate the interface unit with hands, and machine operation cannot be realized. In addition, for users whose...
