Abstract: There is provided a smart home control system including a host, at least one sensor, a plurality of controlled devices and an informing device. The host identifies entering and leaving of family members according to detection results of the at least one sensor, and controls on/off of the controlled devices or informs a specific family member by the informing device to execute agenda according to a member ID of a family member who is identified to enter or leave the house. When identifying that one agendum is unable or forgotten to be executed by the specific family member, the host further rearranges the agendum.

Abstract: There is provided an encoding and decoding method and an information recognition device using the same. A code block includes a center coding region and a peripheral coding region arranged around the center coding region. The encoding and decoding method uses the feature of at least one microdot included in the center coding region as codes. The encoding and decoding method uses the feature of at least one microdot included in the peripheral coding region as codes. The encoding and decoding method uses the relative feature between the center coding region and the peripheral coding region as codes. The information recognition device compares the read feature with pre-stored features to decode information such as position codes, object codes, parameter codes and control codes.

Abstract: A joystick includes a casing, a stick body and an optical sensor. The casing has a hole. The stick body is movably disposed on the casing via the hole. The stick body includes a pressing portion, an indication portion and an identification pattern. The indication portion is connected to the pressing portion and inserts into the hole. A sunken structure is formed on a bottom of the indication portion. The identification pattern is disposed on an inner surface of the sunken structure. The optical sensor is disposed inside the casing and faces the sunken structure, and adapted to analyze a movement of the identification pattern to identify a control status of the stick body.

Abstract: An electric pot, which comprises: at least one light source, configured to emit light to liquid in the electric pot, wherein the light forms a first light pattern on a surface of the liquid; an image sensor, configured to detect the first light pattern; and a processor, configured to determine a liquid level of the liquid based on the first light pattern. Further, the processor can determine a solid height of the solid in the liquid based on a second light pattern. Via such electric pot, the liquid level or the solid height can be calculated in an optical manner, thus the user may feel more convenience while using the electric pot.
