A gyroscope is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum.
A smartphone is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing, email, and social media, as well as multimedia playback and streaming. Smartphones have built-in cameras, GPS navigation, and support for various communication methods, including voice calls, text messaging, and internet-based messaging apps.
An accelerometer is a device that measures the proper acceleration of an object. Proper acceleration is the acceleration of the object relative to an observer who is in free fall. 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 acceleration due to Earth's gravity straight upwards of about g ≈ 9.81 m/s2. By contrast, an accelerometer that is in free fall will measure zero acceleration.
A pedometer, or step-counter, is a device, usually portable and electronic or electromechanical, that counts each step a person takes by detecting the motion of the person's hands or hips. Because the distance of each person's step varies, an informal calibration, performed by the user, is required if presentation of the distance covered in a unit of length is desired, though there are now pedometers that use electronics and software to determine how a person's step varies automatically. Distance traveled can be measured directly by a GPS receiver.
A vibrating structure gyroscope (VSG), defined by the IEEE as a Coriolis vibratory gyroscope (CVG), is a gyroscope that uses a vibrating structure to determine the rate of rotation. A vibrating structure gyroscope functions much like the halteres of flies.
Synaptics Incorporated is a publicly owned San Jose, California-based developer of human interface (HMI) hardware and software, including touchpads for computer laptops; touch, display driver, and fingerprint biometrics technology for smartphones; and touch, video and far-field voice technology for smart home devices and automotives. Synaptics sells its products to original equipment manufacturers (OEMs) and display manufacturers.
TDK Corporation is a Japanese multinational electronics corporation that manufactures electronic components and recording and data-storage media. Its motto is "Contribute to culture and industry through creativity".
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
OmniVision Technologies Inc. is an American subsidiary of Chinese semiconductor device and mixed-signal integrated circuit design house Will Semiconductor. The company designs and develops digital imaging products for use in mobile phones, laptops, netbooks and webcams, security and surveillance cameras, entertainment, automotive and medical imaging systems. Headquartered in Santa Clara, California, OmniVision Technologies has offices in the US, Western Europe and Asia.
In computing, a motion controller is a type of input device that uses accelerometers, gyroscopes, cameras, or other sensors to track motion.
Jack McCauley is an American engineer, hardware designer, inventor, video game developer and philanthropist. As an engineer at RedOctane, he designed guitars and drums for the Guitar Hero video game series. He later worked at Oculus VR, which was eventually acquired by Facebook for $2 billion.
Oculus Rift is a discontinued line of virtual reality headsets developed and manufactured by Oculus VR, a virtual reality company founded by Palmer Luckey that is widely credited with reviving the virtual reality industry. It was the first virtual reality headset to provide a realistic experience at an accessible price, utilizing novel technology to increase quality and reduce cost by orders of magnitude compared to earlier systems. The first headset in the line was the Oculus Rift DK1, released on March 28, 2013. The last was the Oculus Rift S, discontinued in April 2021.
mCube is a fabless semiconductor company founded in 2009 and headquartered in San Jose, California, and has offices at multiple locations in Hsinchu, Taipei, Shanghai, and Shenzhen. It manufactures microelectromechanical systems (MEMS) motion sensors.
Oculus Touch is a line of motion controller systems used by Meta Platforms virtual reality headsets. The controller was first introduced in 2016 as a standalone accessory for the Oculus Rift CV1, and began to be bundled with the headset and all future Oculus products beginning in July 2017. Since their original release, Touch controllers have undergone revisions for later generations of Oculus/Meta hardware, including a switch to inside-out tracking, and other design changes.
A virtual reality headset is a head-mounted device that provides a virtual reality environment for the wearer. 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, 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.
In virtual reality (VR) and augmented reality (AR), a pose tracking system detects the precise pose of head-mounted displays, controllers, other objects or body parts within Euclidean space. Pose tracking is often referred to as 6DOF tracking, for the six degrees of freedom in which the pose is often tracked.
The Sony Xperia XZ2 is an Android-based smartphone unveiled, manufactured, released and marketed by Sony. Part of the Xperia X series, the device was announced to the public along with the Xperia XZ2 Compact at a press conference held at the annual 2018 Mobile World Congress event on February 26, 2018. It features Qi wireless charging, Dynamic Vibration System, 4K HDR video recording and has the standard 3.5 mm headphone jack removed.
The first-generation Oculus Quest is a discontinued virtual reality headset developed by Oculus, a brand of Facebook Inc., and released on May 21, 2019. Similar to its predecessor, Oculus Go, it is a standalone device, that can run games and software wirelessly under an Android-based operating system. It supports positional tracking with six degrees of freedom, using internal sensors and an array of cameras in the front of the headset rather than external sensors. The cameras are also used as part of the safety feature "Passthrough", which shows a view from the cameras when the user exits their designated boundary area known as "Guardian". A later software update added "Oculus Link", a feature that allows the Quest to be connected to a computer via USB, enabling use with Oculus Rift-compatible software and games.
Oculus Rift CV1, also known simply as Oculus Rift, is a virtual reality headset developed by Oculus VR, a subsidiary of Meta Platforms, known at the time as Facebook Inc. It was announced in January 2016, and released in March the same year. The device constituted the first commercial release in the Oculus Rift lineup.
The iPhone's hardware is designed by Apple Inc. Apple directly sub-contracts hardware production to external OEM companies, maintaining a high degree of control over the end product.
