摘要： The invention relates to a method for issuing an input to a computer from a head-mounted device, the head-mounted device comprising a processing unit and a memory as well as at least one position and/or movement sensor, the head-mounted device being in communication with the computer, the method being implemented while the head-mounted device is worn on a wearer's head.
The method comprises steps of:
acquisition of position and/or movement data representative of the movement of the wearer's head by the position and/or movement sensor,
detection of a specific movement pattern based on said position and/or movement data, the specific movement pattern being taken from a library of movement patterns,
determination of a specific input associated with the specific movement pattern in the library, and
issuance of the specific input to the computer.-

摘要： Systems and methods for cleaning a hard-coated ophthalmic lens and stripping the hard-coating of the hard coated ophthalmic lens in a single pass process are disclosed. The hard-coated ophthalmic lens is sequentially treated with a cleaning solution, an alkaline solution, and a stripping solution. Ultrasonic power is applied to the solutions and the ophthalmic lens during the process. The resulted ophthalmic lens has substantially no sign of chemical attack or residual hard coating or varnishes thereon.
