A virtualized peripheral driver and filter are installed at a kernel level of an Operating System (OS) on a host device. A new peripheral driver is installed on the host device and added to the peripheral device stack within the OS. Events generated from the user level of the OS are pushed through the stack for processing by a newly attached peripheral of the host device using the new peripheral driver. Events produced from the kernel for the peripheral are trapped by the filter when passing up through the stack to the user level of the OS and provided to the virtualized peripheral driver. The virtualized peripheral driver repackages, translates, and formats the events produced from the kernel as OS events expected by the OS for processing and the repacked, translated, and formatted events are processed by the OS.

An input device may include at least one touch surface arranged in a three-dimensional (3D) shape wherein the at least one touch surface receives translational and rotational input along three spatial axes. A six degree-of-freedom (6DOF) input system may include at least one touch registering surface formed into a 3D shape to detect an interactive touch from a user and a processor to receive the interactive touch and adjust the position of a three-dimensional (3D) object represented in 3D space on a graphical user interface (GUI).

If an electronic device receives control data in a first format when determining that an input source device is connected to the electronic device in a wired manner, converting the control data in the first format into control data in a second format, where the second format is determined by the electronic device based on a type of an interface that connects the input source device and the electronic device; and sending the control data in the second format to the input source device through the interface that connects the input source device and the electronic device.

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.

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.

Certain embodiments include a computer mouse including a housing having a bottom surface and a trackball disposed in the housing, where the bottom surface of the housing includes a first planar region, a second planar region, and a spine both common to and dividing the first and second planar regions. The first and second planar regions can be on different planes, where, when in operation, the computer mouse is configured to rest on a work surface, when the computer mouse is configured such that the first planar region of the bottom surface is parallel to the work surface, the computer mouse is tilted at a first angle relative to the work surface, and when the computer mouse is configured such that the second planar region of the bottom surface is parallel to the work surface, the computer mouse is tilted at a second angle relative to the work surface.

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 roller module includes a roller, a swinging arm, a movable block and an adjusting device. The roller includes a recess with a toothed surface. The swinging arm includes a contacting part, a linking part and an adjusting part. The contacting part is connected with a first elastic element. In response to an elastic force of the first elastic element, the contacting part provides a pressing force to the toothed surface. When the adjusting part is pushed by the movable block, the swinging arm performs a swinging motion. The movable block is pushed by the piston. While the position of the piston is adjusted by the adjusting device, the movable block is moved and the swinging arm performs the swinging motion. The pressing force of the contacting part provided to the toothed surface is adjusted in response to the swinging motion.
