Abstract: Disclosed is a smart head-mounted device, and the smart head-mounted device comprises at least one lens and at least one arm, the arm is connected to the lens and has a cavity therein; further comprises a sound production apparatus provided inside the cavity and dividing the cavity into a front acoustic cavity and a back acoustic cavity; a sound outlet and a main sound leakage hole provided on the arm, the sound outlet is in communication with the front acoustic cavity, and the main sound leakage hole is in communication with the back acoustic cavity.

Abstract: Disclosed is a smart head-mounted device, comprising: at least one lens and at least one arm; the arm includes a fixed section and a cooperating section, the fixed section being connected to the lens at one end thereof, the cooperating section being formed as an extension of the fixed section from the other end thereof, the cooperating section functions as an earpiece having a curvature; and a sound production apparatus provided inside the fixed section and provided with a sound outlet, at least part of a structure of the sound outlet facing an area surrounded by the cooperating section, and the sound outlet being configured to guide a sound out; the sound outlet is positioned to avoid direct contact with the ear of the user and is apart from an ear hole of the user by a predetermined distance when the user wears the smart head-mounted device

Abstract: Disclosed is a smart head-mounted device. The smart head-mounted device comprises a lens and an arm connected to the lens, the same arm being provided with a sound production unit including a first sound production apparatus and a second production apparatus. The first sound production apparatus and a second production apparatus radiate sound waves outward through their respective sound outlets, have opposite phases during operation, and are apart from the same ear hole of a wearer by different distances.

Abstract: A method and apparatus for utilizing user behavior to immediately modify sets of search results so that the most relevant documents are moved to the top. In one embodiment of the invention, behavior data, which can come from virtually any activity, is used to infer the user's intent. The updated inferred implicit user model is then exploited immediately by re-ranking the set of matched documents to best reflect the information need of the user. The system updates the user model and immediately re-ranks documents at every opportunity in order to constantly provide the most optimal results. In another embodiment, the system determines, based on the similarity of results sets, if the current query belongs in the same information session as one or more previous queries. If so, the current query is expanded with additional keywords in order to improve the targeting of the results.

Abstract: A novel approach for filtering documents involves the use of delivery ratio threshold setting technique to set an initial profile score threshold and the use of beta-gamma regulation for dynamic threshold updating. A group of documents is scored pursuant to a user profile. The score for each document is indicative of the relevance of the corresponding document to the user profile. The score can be compared with a profile score threshold to decide if the document should be accepted or rejected. According to one aspect of the invention, the initial threshold is set to a score threshold that approximates an expected ratio of acceptable documents calibrated with respect to a set of reference documents. According to another aspect of the invention, the score threshold can be updated based on the accumulated example documents, user's relevance judgment, and the user's utility function. The accumulated example documents are first scored against a profile and a ranked list of scored documents is obtained.
