Augmented Reality
Augmented reality (AR), also known as mixed reality (MR), is a technology that overlays real-time 3D computer graphics, 3D-rendered computer graphics onto a portion of the real world through a display, such as a handheld device or head-mounted display. This experience is seamlessly interwoven with the physical world such that it is perceived as an immersion (virtual reality), immersive aspect of the real environment. In this way, augmented reality alters one's ongoing perception of a real-world environment, compared to virtual reality, which aims to completely replace the user's real-world environment with a simulated one. Augmented reality is typically visual, but can span multiple sensory Modality (human–computer interaction), modalities, including Hearing, auditory, haptic perception, haptic, and Somatosensory system, somatosensory. The primary value of augmented reality is the manner in which components of a digital world blend into a person's perception of the real world, ...

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 ...

Progressive Lens
Progressive lenses are corrective lenses used in glasses, eyeglasses to correct presbyopia and other disorders of accommodation reflex, accommodation. They are characterised by a gradient of increasing optical power, lens power, added to the wearer's correction for the other refractive errors. The gradient starts at the wearer's distance prescription at the top of the lens (optics), lens and reaches a maximum addition power, or the full reading addition, at the bottom of the lens. The length of the progressive power gradient on the lens surface depends on the design of the lens, with a final addition power between 0.75 and 3.50 dioptres. The addition value prescribed depends on the level of presbyopia of the patient. In general the older the patient, the higher the addition. They are also known as multifocal lenses, progressive addition lenses (PAL), varifocal lenses, progressive power lenses, graduated prescription lenses, or progressive spectacle lenses.

Polarizer
A polarizer or polariser is an optical filter that lets light waves of a specific polarization (waves), polarization pass through while attenuation, blocking light waves of other polarizations. It can filter a beam of light of undefined or mixed polarization into a beam of well-defined polarization, known as polarized light. Polarizers are used in many optics, optical techniques and optical instrument, instruments. Polarizers find applications in photography and liquid crystal display, LCD technology. In photography, a polarizing filter (photography), polarizing filter can be used to filter out reflections. The common types of polarizers are linear polarizers and circular polarizers. Polarizers can also be made for other types of electromagnetic waves besides visible light, such as radio waves, microwaves, and X-rays. Linear polarizers ''Linear polarizers'' can be divided into two general categories: absorptive polarizers, where the unwanted polarization states are absorption ...

Ray-Ban Wayfarer
Ray-Ban Wayfarer sunglasses and eyeglasses have been manufactured by Ray-Ban since 1952. Made popular in the 1950s and 1960s by music and film icons such as Buddy Holly, Roy Orbison and James Dean, Wayfarers almost became discontinued in the 1970s, before a major resurgence was created in the 1980s through massive product placements. The Ray-Ban brand was sold to Italian Luxottica Group in 1999, who created a second revival in the mid 2000s.Derrick, Gabrielle. "The world's favorite shades turn 40". ''The Age'' (October 3, 1993).

Ray-Ban Stories Charging Mechanism
Ray-Ban is a brand of luxury sunglasses and eyeglasses created in 1936 by Bausch & Lomb. The brand is best known for its Wayfarer and Aviator lines of sunglasses. In 1999, Bausch & Lomb sold the brand to Italian eyewear conglomerate Luxottica Group for a reported $640 million. History In 1929, US Army Air Corps Colonel John A. Macready worked with Bausch & Lomb, a Rochester, New York–based medical equipment manufacturer, to create aviation sunglasses that would reduce the distraction for pilots caused by the intense blue and white hues of the sky. Specifically, Macready was concerned that pilots' goggles would fog up, greatly reducing visibility at high altitude. The prototype, created in 1936 and known as "Anti-Glare", had plastic frames and green lenses that could cut out the glare without obscuring vision. The name "Ray-Ban" was hence derived from the ability of these glasses to limit the ingress of either ultra-violet or infra-red rays of light. Impact-resistant lenses we ...

Validation Test
In engineering and its various subdisciplines, acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical tests, physical tests, or performance tests. In systems engineering, it may involve black-box testing performed on a system (for example: a piece of software, lots of manufactured mechanical parts, or batches of chemical products) prior to its delivery. In software testing, the ISTQB defines ''acceptance testing'' as: The final test in the QA lifecycle, user acceptance testing, is conducted just before the final release to assess whether the product or application can handle real-world scenarios. By replicating user behavior, it checks if the system satisfies business requirements and rejects changes if certain criteria are not met. Some forms of acceptance testing are, user acceptance testing (UAT), end-user testing, operational acceptance testing (OAT), acceptance test-driven development (ATDD ...

Color Image Pipeline
An image pipeline or video pipeline is the set of components commonly used between an image source (such as a camera, a scanner, or the rendering engine in a computer game), and an image renderer (such as a television set, a computer screen, a computer printer or cinema screen), or for performing any intermediate digital image processing consisting of two or more separate processing blocks. An image/video pipeline may be implemented as computer software, in a digital signal processor, on an FPGA, or as fixed-function ASIC. In addition, analog circuits can be used to do many of the same functions. Typical components include image sensor corrections (including debayering or applying a Bayer filter), noise reduction, image scaling, gamma correction, image enhancement, colorspace conversion (between formats such as RGB, YUV or YCbCr), chroma subsampling, framerate conversion, image compression/video compression (such as JPEG), and computer data storage/data transmission.
