  • Publication number: 20240111178
    Abstract: A contact lens comprises an optical zone and a peripheral zone. The optical zone is used for vision correction. The peripheral zone surrounds the optical zone. The optical zone and the peripheral zone jointly define a geometric center and a horizontal axis passing through the geometric center. Two stabilization zones symmetrically arranged relative to the geometric center are formed in the peripheral zone. These stabilization zones gradually thicken relative to a base curved surface of the peripheral zone.

  • Patent number: 11164094
    Abstract: A device, method, and non-transitory computer readable storage medium for labelling motion data are provided. The device receives several motion signals, wherein each motion signal includes a motion time message and a motion data group. A motion script includes a plurality of preset motion messages, wherein each preset motion message includes a preset time message and a preset motion. The device performs the following steps for each preset time message: determining a first subset of the motion signals by comparing the motion time messages with the preset time message, calculating a similarity between the motion data group of each motion signal in the first subset and a reference model, determining a second subset of the first subset based on the first similarities, and labelling the motion data group of each motion signal included in the second subset as corresponding to the preset motion corresponding to the preset time message.

  • Patent number: 8870575
    Abstract: A language learning system including a storage module, a feature extraction module, and an assessment and diagnosis module is provided. The storage module stores training data and an assessment decision tree generated according to the training data. The feature extraction module extracts pronunciation features of a pronunciation given by a language learner. The assessment and diagnosis module identifies a diagnosis path corresponding to the pronunciation of the language learner in the assessment decision tree and outputs feedback information corresponding to the diagnosis path. Thereby, the language learning system can assess and provide feedback information regarding words, phrases or sentences pronounced by the language learner.
