In an electronic information processing system, a brain activity detection unit detects an activity of a user's brain. A change determination part determines whether a character input mode presently set needs to be changed to a different character input mode based on a detection result of the brain activity detection unit after a character input under the character input mode presently set is displayed on a display unit. When the change determination part determines that the character input mode presently set needs to be changed to the different character input mode, the character input mode setting part sets the different character input mode instead of the character input mode presently set.

There is provided herein an improved keyboard layout that has a particular alphabetical, numerical, functional and symbolic key layout that enhances keyboard layout compactness and hand specialisation. The symbolic key layout allows for the incorporation of a much larger symbol character set wherein more frequently used symbols are more readily accessible and more conveniently located. This particular layout may be overlaid with extended Latin and, in embodiments, Greek characters to facilitate typing of most Western European languages in ways which do not affect the symbol key layout, facilitates finding of extended characters and offers one-to-one key mappings between basic and extended symbols for each language.

An information processing apparatus includes: a first processor that executes processing depending on an input signal; and a second processor that transmits a signal to the first processor based on press-down of a key on a keyboard. When press-down of the key is detected before an operating system of the information processing apparatus is booted by being powered on, the second processor transmits to the first processor a signal that corresponds to processing that is fixed in advance among a plurality of signals associated with the pressed key, and when the press-down of the key is detected after the booting of the operating system of the information processing apparatus, the second processor transmits to the first processor a signal that corresponds to processing that is set by a user among the plurality of signals.

An input device of the present disclosure includes an electrode sheet, a plurality of keys, and a controller. The electrode sheet directly senses a change in capacitance at a position where an object approaches when the object approaches the electrode sheet. The plurality of keys are depressibly disposed on the electrode sheet. The controller detects capacitance change amounts at a plurality of positions on the electrode sheet, outputs positional information indicating the position, among the plurality of positions, at which a capacitance change amount detected satisfies a first given condition, and outputs key information indicating a key among the plurality of keys corresponding to the position, among the plurality of positions, at which a capacitance change amount detected satisfies a second given condition.

The character input keyboard. One shift key and one space key are placed on the home position of the left and right thumb, and one control key is placed between them. These keys have the width from 1 to 1.5 times of the character key.

A securing member is disposed so as to face an operation face of a touch panel, and a cover panel is disposed on a back side of a face of the securing member that faces the touch panel. The cover panel is provided with a cover-panel through-hole, and the securing member is provided with a securing-member through-hole that is wider than the cover-panel through-hole. A push button unit is disposed in the cover-panel through-hole. Each of the cover-panel through-hole and the push button unit has a tapered shape narrowing in a direction from the touch panel toward the cover panel.

A control section allows a screen of a display section to display a plurality of numeric keys, detects a touch gesture on the individual numeric key through a touch panel to allow an input of a numeric number corresponding to the numeric key subjected to the touch gesture, and detects an action on each of hard keys to accept an instruction to perform a function corresponding to the hard key subjected to the action. When a predetermined action is performed on one or more individuals of the hard keys, the control section assigns numeric numbers to the respective hard keys and detects an action on the individual hard key to allow an input of the numeric number corresponding to the hard key subjected to the action.

An input assistance device has a rotation support body having a central axis, an attachment mechanism that removably attaches the rotation support body to the panel surface of a sensor panel so that the central axis is along a direction perpendicular to the panel surface, and a rotational part supported by the rotation support body so as to be rotatable around the central axis. At least the side surface of the rotational part is formed from a conductive material. Conductive areas electrically connected to the side surface are allocated in part of a surface of the rotational part, the surface facing the panel surface.
