Field Of View
The field of view (FOV) is the angle, angular extent of the observable world that is visual perception, seen at any given moment. In the case of optical instruments or sensors, it is a solid angle through which a detector is sensitive to electromagnetic radiation. It is further relevant in ''angle of view, photography''. Humans and animals In the context of human and primate vision, the term "field of view" is typically only used in the sense of a restriction to what is visible by external apparatus, like when wearing spectacles or virtual reality goggles. Note that eye movements are allowed in the definition but do not change the field of view when understood this way. If the analogy of the eye's retina working as a sensor is drawn upon, the corresponding concept in human (and much of animal vision) is the visual field. It is defined as "the number of degrees of visual angle during stable fixation of the eyes".Strasburger, Hans; Pöppel, Ernst (2002). Visual Field. In G. A ...

Virtual Reality Headsets
A virtual reality headset (or VR headset) is a head-mounted device that uses 3D near-eye displays and positional tracking to provide a virtual reality environment for the user. VR headsets are widely used with VR video games, but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display (providing separate images for each eye), stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world. Augmented reality (AR) headsets are VR headsets that enable the user to see and interact with the outside world. Examples of AR headsets include the Apple Vision Pro and Meta Quest 3. VR headsets typically use at least one MEMS IMU for three degrees of freedom (3DOF) motion tracking, and optionally more tracking technology for six degrees of freedom (6DOF) motion tracking. 6DOF devic ...

VirtualLink
VirtualLink was a proposed USB-C Alternate Mode that was historically intended to allow the power, video, and data required to power virtual reality headsets to be delivered over a single USB-C cable instead of a set of three different cables as it was in older headsets. The standard was supported by Nvidia, AMD, HTC Vive, Oculus VR, Valve, and Microsoft. The VirtualLink Consortium was chaired by Rambo Jacoby representing Nvidia. VirtualLink specifications According to its specifications, the VirtualLink cable consisted of: * DisplayPort: ** 4 × DisplayPort balanced pair data path ** DisplayPort HPD (hot-plug detection pin) as a single wire. ** DisplayPort AUX signal as a balanced pair * USB 3.1 signals ** A USB TX balanced pair for USB 3.0 data ** A USB RX balanced pair for USB 3.0 data * I2C wire to control the USB Billboard interface, in case the cable is plugged into an unsupported interface. * VBUS carrying power to HMD visor * GND ground The USB-C plug pinout specified ...

Accelerometer
An accelerometer is a device that measures the proper acceleration of an object. Proper acceleration is the acceleration (the rate of change (mathematics), rate of change of velocity) of the object relative to an observer who is in free fall (that is, relative to an inertial frame of reference). Proper acceleration is different from coordinate acceleration, which is acceleration with respect to a given coordinate system, which may or may not be accelerating. For example, an accelerometer at rest on the surface of the Earth will measure an Gravitational acceleration, acceleration due to Earth's gravity straight upwards of about Standard gravity, ''g'' ≈ 9.81 m/s2. By contrast, an accelerometer that is in free fall will measure zero acceleration. Accelerometers have many uses in industry, consumer products, and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. In unmanned aerial vehicles, accelerometers help to stabili ...

Touchpad
A touchpad or trackpad is a type of pointing device. Its largest component is a tactile sensor: an electronic device with a flat surface, that detects the motion and position of a user's fingers, and translates them to 2D motion, to control a Cursor (user interface)#Pointer, pointer in a graphical user interface on a computer screen. Touchpads are common on Laptop, laptop computers, contrasted with desktop computers, where Computer mouse, mice are more prevalent. Trackpads are sometimes used with desktop setups where desk space is scarce. Wireless touchpads are also available, as detached accessories. Due to the ability of trackpads to be made small, they were additionally used on personal digital assistants (PDAs) and some portable media players. Operation and function Touchpads operate in several ways, including capacitive sensing or resistive touchscreen. The most common technology used in the 2010s senses the change of capacitance where a finger touches the pad. Capacitance ...

Analog Stick
An analog stick (analogue stick in British English), also known as a control stick, thumbstick or joystick, is an input method designed for video games that translates thumb movement into directional control. It consists of a protruding stick mounted on a pivot, with movement registered through continuous electrical signals rather than discrete switches, allowing for greater nuance than traditional digital inputs. Unlike D-pads, which rely on fixed electrical contacts, analog sticks use potentiometers to measure their position across a full range of motion. Many models allow the stick to be pressed down like a button, allowing users to execute commands without removing their thumb from the stick. Since its introduction, the analog stick has largely replaced the D-pad as the primary directional input in modern game controllers. Usage in video games The initial prevalence of analog sticks was as peripherals for flight simulator games, to better reflect the subtleties of control ...

Backward Compatibility
In telecommunications and computing, backward compatibility (or backwards compatibility) is a property of an operating system, software, real-world product, or technology that allows for interoperability with an older legacy system, or with Input/output, input designed for such a system. Modifying a system in a way that does not allow backward compatibility is sometimes called "wikt:breaking change, breaking" backward compatibility. Such breaking usually incurs various types of costs, such as Switching barriers, switching cost. A complementary concept is ''forward compatibility''; a design that is forward-compatible usually has a Technology roadmap, roadmap for compatibility with future standards and products. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM broadcasting, FM radio in stereophonic sound, stereo. FM radio was initially monaural, mono, with only one audio channel represented by one signal (electrical engineerin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
