The disclosure provides a restart control device and a restart control method. The restart control device is disposed in an electronic device. The electronic device includes a keyboard and a restart button. At least one assigned key of a plurality of keys of the keyboard is set. The restart control device determines whether the at least one assigned key is pressed, and determines whether the restart button is pressed. When determining that the restart button is pressed and the at least one assigned key is pressed, the restart control device provides a restart control signal to cause the electronic device to perform a restart operation. The disclosure can prevent an unnecessary restart operation due to a single restart button being mistyped.

A data entry system comprises a processor configured to receive a first data entry, make a first determination whether the first data entry is a first character entry or a first chorded entry, select a first output based on the first determination, and transmit the first output. The processor is further configured to receive, after transmitting the first output, a second data entry; make a second determination whether the second data entry is a second character entry or a second chorded entry; select a second output based on the second determination; and transmit the second output. The first data entry is the first character entry and the second data entry is the second chorded entry, or the first data entry is the first chorded entry and the second data entry is the second character entry.

A method for processing user input entered via a data entry system includes the steps of receiving a signal representative of a contact of one or more fingers singly or in combination against an arbitrary surface; detecting a predetermined number of contacts within a time window; and mapping the predetermined number of contacts to a secondary character from a set of secondary characters.

A method and device for reading, writing, and communication by deafblind users is provided to enable such exemplary functions as word processing, text messaging, Internet access, and telephonic communication. By combining a chordic keyboard for user input with a self-scrolling Braille pad for reading Braille, embodiments of the invention enable the user's hands to stay in place on a user console rather than having to constantly switch back and forth between typing messages versus reading or checking for messages. This in turn enables duplex communication because the user can read or acknowledge incoming messages even while typing. It also reduces the dynamic complexity experienced in reading Braille because a body part used for reading Braille can remain constantly available for receiving messages simply by resting in place on the self-scrolling Braille pad without any swiping, thereby eliminating swiping gestures and the problem of timing them with the receipt of messages.

A one-handed, chorded data entry system enables an operator to tap a combination of fingers on any surface, thereby causing a character or command to be entered on an electronic device. The fingers can be arranged in any position and neither the fingers nor the fingertips of the user need be aimed at any particular target. Data indicating contact by finger combinations sharing a similar characteristic is mapped to characters sharing a similar characteristic. For example, data indicating contact by only one of five fingers during a data collection period is mapped to a respective one of the five vowels.

A starting method for inputting Morse code and a portable electronic device thereof are provided. The starting method for inputting Morse code is performed in the portable electronic device that includes a first physical button, a second physical button, a sensing circuit and a processing circuit. The starting method for inputting Morse code includes steps of: when the portable electronic device is switched to a sleep mode or a shutdown mode, enabling the sensing circuit to sense whether the first physical button and the second physical button are simultaneously pressed by a user; and when the first physical button and the second physical button are simultaneously pressed by the user, enabling the processing circuit to generate a longer mark of Morse code or a shorter mark of Morse code according to the duration for which the user presses the first physical button or the second physical button.

An electronic device and method are disclosed herein. The electronic device includes a housing, a plurality of physical keys arranged on the housing, a memory and a processor. The processor implements the method, including receiving an input generated by activation of two or more of a plurality of physical keys, identifying an operation state of the electronic device based on reception of the input, when the input is received in a first state in which a screen is displayed, executing a first operation related to the displayed screen in response to the received input, and when the input is received in a second state in which an application is processing audio/video (A/V) data, executing a second operation of initiating recording of the A/V data using a memory in response to the received input.

Disclosed is a multilingual character input device. The multilingual character input device comprising a keyboard unit for displaying character phonemes converted from characters per language in a software-selected country on a key and selectively receiving the input of the displayed character phonemes; a display unit for displaying the received input character on a display; a storage unit for storing character phonemes, a list of data and a program; and, a control unit for controlling the keyboard unit and the display unit, wherein, the keyboard unit comprises: a numeric/symbol keys section for displaying numbers and symbols disposed at an upper part; an F keys section disposed below the numeric/symbol keys section for displaying functions, characters or preset functions and plurality of F keys are addible; a character keys section disposed below the F keys section for displaying basic phonemes of each language, and; a plurality of additional keys in the character keys section for displaying variant phonemes or preset symbols, wherein if language conversion is performed through a language conversion key of the keyboard unit, a language exceeding the phoneme number of the character keys section is assigned to the F keys section and the plurality of additional keys so as to display all character phonemes, so that the input of the characters for each language is received by one key stroke.

A touch sensing method is provided. The touch sensing method is applied to an electronic device with a touchable unit. The touch sensing method comprises the following steps: sensing a touch event by using the touchable unit; detecting a current operation mode; triggering a corresponding touch operation according to the touch event when the current operation mode is a touch recognition mode; determining whether the touch event is touch gesture input or key input when the current operation mode is a key recognition mode; triggering corresponding key operation according to the key input when the touch event is the key input; and triggering a corresponding touch operation according to the touch gesture input when the touch event is the touch gesture input.

A one-handed input chording user input device for converting finger movements into digital input has a chassis configured to conform to human fingers with a plurality of articulating finger frames connected adjacent to each other, a plurality of user input elements, a processing device, and a signal transmitter. The plurality of user input elements is connected around the chassis in order to capture flexion, extension, adduction, and abduction movements of the plurality of articulating finger frames. The processing device interprets signals received from the plurality of articulating finger frames into desired output communication elements such as text characters. The signal transmitter sends the interpreted output to a computing device.
