An electronic device comprises a touch screen, a distance determining module, a touch determining module, and a warning control module. The distance determining module determines whether a distance between the touch screen and an object in front of the touch screen is less than or equal to a distance limit. The touch determining module determines whether a touch action is applied to the touch screen within a first predetermined time when the distance between the touch screen and the object is less than or equal to the distance limit. The warning control module controls the electronic device to send a warning to a user when no touch action is applied to the touch screen within the first predetermined time.

A method for inputting characters into an electronic device by receiving proximity signals from proximity sensors. The proximity sensors include a first proximity sensor and at least one proximity sensor. Predetermined character types are displayed on the display device after enabling the proximity sensors. A character type from the predetermined character types is selected by receiving a proximity signal from the first proximity sensor, and a predetermined number of characters of the selected character type are displayed on the display device. Then, a character of the selected character type is input into the electronic device after receiving a proximity signal from the second proximity sensor.

A multi-use switch for an electronic device includes a pressing piece configured to be pressed by an external force, a number of conducting elements located on the pressing piece and electrically coupled to a number of functional circuits of the electronic device one-to-one, and at least one coupling element configured to be electrically coupled to the conducting elements. The multi-use switch is partially received inside a housing. The coupling element is fixed to the housing. The pressing piece moves along an axis to move the conducting elements relative to the coupling element. The coupling element completes an electric circuit of one of the functional circuits when the corresponding conducting element is moved to electrically couple to the at least one coupling element. One electric circuit of the functional circuits is able to be completed at any one time.

A handwriting input recognizing method comprises following steps. Recognize an initial touch point of a touch. Determine an input region associated with the initial touch point. Display the input region. Recognize and display a handwritten input in the input region. Determine whether there is a handwritten input reaches the boundary of the input region. If yes, recognize and display the letters associated with the handwritten input and determine whether the input region receives another handwritten input during a predefined time duration. If yes, determine the sting of letters associated with the handwritten input is a first portion of a complete word, and the sting of letters associated with the another handwritten input is a last portion of the complete word. Combine the first portion and the last portion into a complete word. display letters of the first portion and the last portion in a substantially same size.

A computing device and a method process point clouds of an object. The computing device controls a rotating device connected to the computing device to rotate to one or more rotation angles of the rotating device. The computing device generates a first coordinate system and one or more second coordinate systems according to one or more rotation angles of the rotating device, and obtains a point cloud of an object based on each of the second coordinate systems from a scanner of the rotating device. The computing device converts the point cloud of the object based on each of the second coordinate systems to a point cloud of the object based on the first coordinate system, and joints all point clouds of the object based on the first coordinate system.

A height measurement method is provided. The method includes: detecting, at a sensor of an electronic device, a distance between the electronic device and an object to be measured; emitting, from two apertures of the sensor, two beams of light, wherein one of the beams is directed at a first end of the object to form a first light spot at the first end of the object and the other one of the beams is directed at a second end of the object to form a second light spot at the second end of the object; obtaining, at the electronic device, a first angle between one of the beams and a horizontal line and a second angle between the other one of the beams and the horizontal line; and calculating, at the electronic device, a height of the object based on the first and second angles and the distance.
