INFORMATION PROCESSING APPARATUS, OPERATION INPUT METHOD, AND SENSING DEVICE
First Claim
1. An information processing apparatus, comprising:
- an operation surface;
a first sense unit for electrically detecting whether said operation surface is being directly touched;
a second sense unit for detecting whether a position pointing device approaches or contacts said operation surface based on an electromagnetic interaction generated between the position pointing device and said second sense unit;
an approach detecting unit for detecting whether the position pointing device is within a detection range from said operation surface based on an output from said second sense unit; and
a display control unit for disabling display processing based on a detection output from said first sense unit and for enabling display processing based on a detection output from said second sense unit if said approach detecting unit determines that the position pointing device is within of said detection range,wherein said display control unit continuously disables display processing based on the detection output from said first sense unit if said first sense unit detects that said operation surface is touched when the position pointing device is moved outside of said detection range from a state in which the position pointing device lies within said detection range, andwherein said display control unit enables display processing based on the detection output from said first sense unit if said first sense unit does not detect that said operation surface is touched.

Abstract
An information processing apparatus includes an operation surface, a first sense unit for electrically detecting whether the operation surface is directly touched, a second sense unit for detecting whether the position pointing device approaches or contacts the operation surface based on an electromagnetic interaction, and an approach detector for detecting whether the position pointing device approaches a detection range from the operation surface based on an output from the second sense unit. The information processing apparatus further includes a display controller for disabling display processing based on a detection output from the first sense unit and for enabling display processing based on a detection output from the second sense unit if the approach detecting unit determines that the position pointing device is within of the detection range.

9. A method of accepting input based on operation by an operation input apparatus comprising an operation surface, the method comprising:
-
a first detection processing for electrically detecting whether said operation surface is being directly touched; a second detection processing for detecting whether a position pointing device approaches or contacts said operation surface based on an electromagnetic interaction generated between the position pointing device and said operation surface; an approach detection processing for detecting whether the position pointing device is within a detection range from said operation surface based on an output from said second detection processing; and a display control processing for disabling display processing based on a detection output from said first detection processing and for enabling display processing based on a detection output from said second detection processing if said approach detection processing determines that the position pointing device is within of said detection range, and wherein said display control processing continuously disables display processing based on the detection output from said first detection processing if said first detection processing detects that said operation surface is touched when the position pointing device is moved outside of said detection range from a state in which the position pointing device lies within said detection range, and wherein said display control processing enables display processing based on the detection output from said first detection processing if said first detection processing does not detect that said operation surface is touched.
