  • Patent number: 8681096
    Abstract: Touchpad devices emulating button functionality (“click pad” devices) that simultaneously emulates multiple functionalities are described herein. In addition, embodiments provide for click pad emulation of both TrackPoint and touchpad functionality. According to embodiments, a click pad device emulating multiple functionalities may enable or disable certain functionalities based on user interaction with the click pad device. For example, a click pad device emulating both TrackPoint and touchpad functionality may enable TrackPoint functionality and disable touchpad functionality if user gestures on the click pad device indicate that the user is interacting with the click pad as a TrackPoint device.

    Abstract: A mouse device includes a lower cover, a circuit board, a first switch, a second switch, a first swinging element, and a second swinging element. The first swinging element includes a first pressing part and a second pressing part. The first swinging element and the second swinging element are located at a front side and a rear side of the lower cover, respectively. As the mouse device is swung in a leftward direction or a rightward direction, the front side and the rear side of the mouse device are simultaneously tilted. Moreover, since the first pressing part or the second pressing part of the first swinging element is pushed by a working surface where the mouse device is placed, the first pressing part or the second pressing part is moved toward the first switch or the second switch in order to trigger the first switch or the second switch.

  • Patent number: 8644769
    Abstract: Input devices such as computer mice are commonly used for interacting with personal computers (PCs). Increasingly, wireless computer mice are becoming popular with users due to their ability to provide cordless accessibility for interaction with the PCs. The wireless computer mice are usually powered using batteries and uses radio frequencies (RF) for transmitting the users' input to the PCs. The wireless computer mice usually have a fixed transmission power, thus resulting in a fixed transmission range. Notably, the battery life and transmission range of the wireless mice share an inversely proportional relationship. Hence, a long battery life cannot be obtained without decreasing the transmission range and vice versa. However, existing wireless computer mice typically do not have provisions for making such adjustments. An embodiment of the invention describes an apparatus and a method for managing power usage of wireless input devices.

    Abstract: A user interface can enable a user to control the display of content in a way that is natural for the user and requires little physical interaction. The gaze direction and/or viewing location of a user can be determined using any of a variety of imaging or other such technologies. By determining the location at which the user is gazing, an electronic device can control aspects such as the scroll rate or page turns of displayed content. In many cases, a device utilizes the natural reading or viewing style of a user to determine appropriate aspects for that user, and can update automatically as conditions change based at least in part upon the change in gaze location and/or viewing patterns.

  • Publication number: 20140015752
    Abstract: A power-saving method for a wheel mouse is provided. The power-saving method is used to control the illumination cycle of a light emitter by judging whether a scroll wheel is triggered or judging whether the output signal from the light receiver is changed. In a case that the illumination cycle of the light emitter is a shorter second cycle, the light emitter can quickly generate the optical signal. Consequently, the optical signal is not lost, and the possibility of erroneously operating the wheel mouse is eliminated. Whereas, in a case that the illumination cycle of the light emitter is a longer first cycle, the controlling unit can reduce the power consumption in order to achieve the power-saving efficacy.

  • Patent number: 8576172
    Abstract: A touch system comprises overlapping coordinate input sub-regions defining a generally contiguous input surface. Each coordinate input sub-region generates pointer coordinate data in response to pointer contacts thereon. When a pointer contact is made on a region of a coordinate input sub-region that overlaps with an adjacent coordinate input sub-region, each overlapping coordinate input sub-region processes acquired images to derive pointer data and triangulates the position of the pointer using the derived pointer data. Thereafter, the triangulated positions generated by the overlapping coordinate input sub-regions are processed in accordance with defined logic thereby to determine the position of the pointer contact relative to the touch surface.

  • Patent number: 8570194
    Abstract: Architecture for managing clutch height in an optical navigational device such as a computer mouse. In one embodiment for a mouse, a feature can be molded into the bottom case that limits the clutch height by occluding the reflected light to the image sensor when the device is lifted from the tracking surface. Tracking is disabled when the clutch height threshold is exceeded, and re-enabled when the device is brought under the distance clutch height threshold. The device includes firmware controlled algorithm adjustments to one or more correlation parameters. When employing a D-shaped aperture, a threshold can be placed on the z-axis height tracking distance using dimensional characteristics of the shaped aperture, such as a knife-edge (the straight portion of the “D” shaped aperture), to impose a shadow across the image sensor. The aperture can be custom designed to occlude a portion of the emitted light from an LED.

  • Patent number: 8553935
    Abstract: A system that has a remote control, e.g., a wand, equipped with a relative motion sensor that outputs data indicative of a change in position of the wand. The system also has one or more light sources and a photodetector that detects their light and outputs data indicative of the detected light. The system uses one or more controllers to determine the absolute position of the wand based on the data output by the relative motion sensor and by the photodetector. The data enables determination of the absolute pose of the wand, which includes the absolute position of a reference point chosen on the wand and the absolute orientation of the wand. To properly express the absolute parameters of position and/or orientation of the wand a reference location is chosen with respect to which the calculations are performed. The system is coupled to a display that shows an image defined by a first and second orthogonal axes such as two axes belonging to world coordinates (Xo,Yo,Zo).
