摘要： An optical touch-sensitive device detects touch events caused by instruments (e.g., pens, styluses) and distinguishes these events from touch events caused by fingers. In some embodiments, different instruments can also be distinguished. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. The optical beams preferably are multiplexed in a manner so that many optical beams can be received by a detector simultaneously. Touch events disturb the optical beams, for example due to frustrated total internal reflection. Information indicating which optical beams have been disturbed is analyzed to detect one or more touch events. The analysis also distinguishes instrument touch events from finger touch events.

摘要： An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. Touch events disturb the optical beams. Touch event templates are used to determine the actual touch events based on which optical beams have been disturbed.

摘要： An optical touch-sensitive device includes a touch-sensitive surface over which touch events are detectable. The device also includes surface features on the surface that reduce touch object friction relative to an absence of surface features. Emitter and detectors are arranged along a periphery of the touch-sensitive surface. The emitters can produce optical beams that travel across the touch-sensitive surface to the detectors. Touches on the touch-sensitive surface disturb the optical beams and the touch-sensitive device determines touch events based on the disturbed optical beams. The surface features may also be arranged to reduce glare by diffusing light. In some embodiments, an anti -reflective layer is on top of the touch-sensitive surface and the surface features.

摘要： An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events. The optical touch-sensitive device can include an optical waveguide, an emitter, and an emitter coupler. The emitter produces optical beams, and the emitter coupler is on a surface of the waveguide and is configured to direct at least some of the optical beams to propagate via total internal reflection (TIR) through the waveguide as coupled optical beams. Touches on the top surface of the waveguide disturb the coupled optical beams, and the touch-sensitive device determines touch events based on the disturbances.

摘要： An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events on a surface. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. Touch events on the surface disturb the optical beams received by the detectors. Responsive to a touch event, the disturbed beams are identified and evaluated. Beams disturbed by two or more touches may be ignored. Alternatively, a beam response may be adjusted for a given touch event based on an estimated contribution of another touch event that also disturbs the beam. Additionally, touch events may be characterized as contamination touch events based on one or more past touch events.

摘要： An optical touch-sensitive device is able to determine the locations of multiple simultaneous touch events on a surface. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. Touch events on the surface disturb the optical beams received by the detectors. Based on the disturbed beams, a map of the touch activity on the surface is generated. Touch characteristics and touch types for each touch event are determined from the map. By applying the touch characteristics and touch types to contextual information, a machine learned model, or a set of predefined rules, touches can be classified as wanted or unwanted touch events. Unwanted touch events may be ignored to improve user experience.

摘要： A stylus is communicatively coupled to a touch-sensitive device. The stylus includes a contact sensor and a reporting unit. The stylus or touch-sensitive device includes a contact detection controller. The contact sensor measures one or more properties. The contact detection controller determines, based on measurements of the one or more properties from the contact sensor, whether the stylus is in contact with a surface. The reporting unit transmits an indication of whether the stylus is in contact with the surface to the touch-sensitive device.

摘要： A touch sensitive surface has emitters and detectors arranged around a periphery of the touch sensitive surface. The emitters produce optical beams that are received by the detectors. A stylus is configured to disturb one or more of the optical beams by a variable amount when in contact with the touch sensitive surface. The variable amount depends on an amount of force applied to the stylus towards the touch sensitive surface. A controller of the touch sensitive surface is configured to determine the touch strength of a touch event performed by the stylus based on disturbances of one or more of the optical beams. The touch strength provides a measure of the amount of force applied to the stylus.

摘要： A touch sensitive optical control device comprising a set of light emitters 14, 22 and light detectors 18, 24 arranged relative to a touchable surface 30 such that light transmitted by the emitters is received by the detectors along multiple intersecting beams which pass transversely of the surface and touching the surface at a beam interrupts the light transmitted along the beam. Candidate touch points T1, T2, F1, F2 are defined at the intersections of interrupted beams and are confirmed or not as actual touch points by examining test beams 40, 42, 54, 56 near to or coincident with the candidate touch point.
