Abstract: An input system and a method for an electronic device based on Chinese phonetic notation are provided. The input system includes a plurality of keys, a detecting unit, a filtering unit and a candidate character output unit. The keys are respectively arranged on two sides of a screen of the electronic device, and each of the keys respectively corresponding to two phonetic notation sets. Every time the detecting unit detects an operation on any of the keys, one of the phonetic notation sets corresponding to the operated key is chosen according to a direction of the operation. The filtering unit permutes the contents of all chosen phonetic notation sets so as to obtain at least one meaningful pronunciation. And according to a Chinese character database and the meaningful pronunciations, the candidate character output unit outputs at least one candidate character on the screen.

Abstract: A method for adjusting touch positions of software keyboard includes the following steps: a software keyboard is displayed on the touch screen. The preset characters are displayed respectively to receive at least one first touched position corresponding to each of the preset characters on the touch screen. A touched offset corresponding to each of the preset characters is calculated according to the at least one first touched position corresponding to each of the preset characters respectively. At least one touched boundary among each of the preset characters and the neighboring characters thereof is calculated according to the touched offset and the preset base center point corresponding to each of the preset characters respectively. A preset close-loop scope corresponding to each of the preset characters is calculated according to the touched boundaries respectively. Output characters according to the close-loop scopes touched.

Abstract: An event triggering method, system, and computer program product are provided, in which an optical spot trajectory tracking is utilized. Firstly, a cursor at a position on the surface of a screen is moved to a preset position through a first optical spot, then, the projecting of the first optical spot is stopped. Next, it is determined whether the preset position is a preset position of a command. Then, a second optical spot is projected to generate a light-triggered signal, and then a processing unit executes the command according to the light-triggered signal.

Abstract: A lock and unlock function triggered by a touch panel of a hand-held device. The hand-held device detects a pattern input from the touch panel, and execute the lock/unlock function to enable or disable the keypad and the touch panel once the input pattern matches the specified pattern using a pattern recognition algorithm.

Abstract: A system and method is used to form a data packet for data synchronization. The data packet comprises a recognizing data and a content data. The recognizing data comprises a guard data and a pattern data. The system and method predetermines bits number of the pattern data, and permutes a plurality of recognizing data sets according to the bits number. Subsequently, the system and method transforms these recognizing data sets to a plurality of counting data sets using the bit mapping procedure. The system and method calculates a plurality of contrast parameter based on these counting data using the half-autocorrelation procedure, and chooses a chosen recognizing data having the smallest. contrast parameter. Finally, the system and method combines the chosen recognizing data and the content data to generate the data packet.
