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, an approach detector for detecting whether the position pointing device approaches a first detection range from the operation surface and whether the position pointing device approaches a second detection range based on an output from the second sense unit. The second detection range is closer to the operation surface than the first detection range. The information processing apparatus further includes a display controller for disabling display processing based on an output from the first sense unit if the approach detector determines that the position pointing device approaches the second detection range and for performing display processing based on an output from the second sense unit.
