Abstract: A traveling apparatus includes a housing, a travel driving unit that drives the housing such that the housing travels along a road surface, a travel environment information acquisition unit that acquires travel environment information concerning an environment around the housing, a communication unit that receives a first travel command value responsive to a travel command from an external control device to the housing, a travel command value converting unit that converts the first travel command value into a second travel command value, and a travel control unit that controls the travel driving unit in response to the second travel command value. The travel command value converting unit varies a conversion rate from the first travel command value to the second travel command value in accordance with the travel environment information.

Abstract: When a user touches a tablet with a pen, a coordinate pointed with a nib of a pen and a tool force on this coordinate are detected, and a cursor is displayed at a position corresponding to the coordinate in a display device. Furthermore, the shape, color and size, etc., of the cursor can be varied according to a change in coordinate, tool force. This permits the user to recognize a level of the tool force which he actually applies at a glance. Additionally, an operational mode is switched according to an amount of change in detected coordinate and the tool force. As a result, the user is permitted to control an operational mode of the document processing device with ease only by a pen operation, thereby improving an operability.
