There is provided an optical navigation device including an image sensor, a processing unit, a storage unit and an output unit. The image sensor is configured to successively capture images. The processing unit is configured to calculate a current displacement according to the images and to compare the current displacement or an accumulated displacement with a threshold so as to determine an outputted displacement. The storage unit is configured to save the accumulated displacement. The output unit is configured to output the outputted displacement with a report rate.

A mouse with an adjustable angle includes an internal body coupled to an upper portion of the lower body in an inner space of the upper body, a plurality of angle adjusting bodies coupled to the upper portion of the lower body to surround the internal body or another angle adjusting body and having one end fixedly coupled to the lower body and the other end detachably coupled to the lower body, and an upper body formed above the lower body so as to surround an angle adjusting body formed at an outermost portion among the angle adjusting bodies and having one end fixedly coupled to the lower body and the other end detachably coupled to the lower body.

A switching assembly for changing relative states of a first object and a second object is provided. The switching assembly includes a fixing member fixed on the first object, a first guiding rod, a second guiding rod, and a moving member movably disposed on the first object. The fixing member has a guiding rib with an extension direction parallel to a first axis, and the first guiding rod is slidably coupled to the guiding rib to move along the first axis. The second object is movably coupled to and driven by the moving member. The second guiding rod is pivoted between the first guiding rod and the moving member in the first axis. The first guiding rod is suited for being forced to move the second guiding rod and the moving member, so as to rotate the second guiding rod relative to the first guiding rod and the moving member.

A portable device (e.g., a wireless device such as a cell phone) is provided with a flexible keyboard and a flexible display screen. Such flexible components may be stored in the housing of the portable device when not in use. The flexible display screen and flexible keyboard may be expanded from the housing when the flexible components are utilized by a user. Non-flexible display and input components may be provided on the exterior of the portable device such that the device may be used, in some form, while the flexible components are stored. In one embodiment, a portion of the flexible display (or flexible keyboard) may be utilized when the flexible display (or flexible keyboard) is stored in said first housing.

The disclosure herein is directed to a computer mouse device, comprising: a) a base comprising a mouse device portion, front mouse pad portion, a left mouse pad portion, a right mouse pad portion, a wrist portion, one more wrist portion mounts, one or more rib mounts, a top surface and a bottom surface; b) an optical computer mouse cage comprising one or more ribs connected to the front mouse pad portion, the left mouse pad portion and/or the right mouse pad portion and traversing to the wrist portion of the base, wherein the ribs have a curved contour for accommodating an optical computer mouse positioned at the mouse pad portion grasped by a user's hand; and c) at least one wrist clamp or wrist strap connected to a left side and a right side of the wrist portion.

In one implementation, a pressure sensitive stylus may receive, at a controller, drawing area coordinates, a stroke pressure from a voltage generated by a piezoelectric crystal, and a stylus coordinate direction from a plurality of fiber optic sensors, determine a drawing area from a wireless signal frequency corresponding to the drawing area coordinates, determine a drawing mode of a stylus stroke, wherein the drawing mode includes a stylus coordinate direction and a stylus stroke type, and transmit the drawing area and the stylus stroke.

The disclosure herein is directed to a computer mouse device, comprising: a) a base comprising a mouse device portion, front mouse pad portion, a left mouse pad portion, a right mouse pad portion, a wrist portion, one more wrist portion mounts, one or more rib mounts, a top surface and a bottom surface; b) an optical computer mouse cage comprising one or more ribs connected to the front mouse pad portion, the left mouse pad portion and/or the right mouse pad portion and traversing to the wrist portion of the base, wherein the ribs have a curved contour for accommodating an optical computer mouse positioned at the mouse pad portion grasped by a user's hand; and c) at least one wrist clamp or wrist strap connected to a left side and a right side of the wrist portion.

A mute-able input device with keystroke tactile feedback includes: a plurality of keys, each including a tactile structure and a sound-generating structure for respectively generating operational tactile feedback and operating sounds; a plurality of adjusting mechanisms, each including an adjusting portion corresponding to one of the keys; at least one switching unit including an operating portion and a switch member, the operating portion connecting the switch member and the adjusting mechanism, the switch member generating a switching signal involving a mode switching between different tactile modes or different sound modes for one or more keys. When the operating portion moves in response to a force, the switch member is triggered to achieve the mode switching; meanwhile, the adjusting portion moves to interfere with at least one of the tactile structure or the sound-generating structure along with the movement of the operating portion.

Provided is a device control apparatus including a first instrument push apparatus and a touch sensing portion operated by an operation of a user and a controller which controls an operation of a user device based on operations by the first instrument push apparatus and the touch sensing portion. The controller outputs sensing commands with respect to the operations with respect to the first instrument push apparatus and the touch sensing portion. Here, a first sensing command is output by sensing the operation with respect to the first instrument push apparatus, and a second sensing command is output by sensing the operation with respect to the touch sensing portion.

An input device includes a top panel including a top portion and side portions, a flexible printed circuit board (PCB) configured to detect the presence of a touch object on the top panel and generate a touch signal based on the presence of the touch object on the top panel, and a first flexible adhesive material disposed below top panel and above the flexible PCB, the first flexible adhesive material coupling flexible PCB to the top panel. In certain embodiments, the top panel is seamless. The flexible PCB can detect the presence of the touch object over the top portion of the top panel where the top portion of the top panel has no dead spots.
