FPGA(also: Field-Programmable Gate Array)

An integrated circuit that can be configured by the user after manufacturing to implement custom digital logic. FPGAs contain an array of programmable logic blocks and interconnects that can be reprogrammed to perform different functions. In assistive technology, FPGAs enable…

Face Swap(also: Face Transformation, Face Replacement)

A technology that replaces the face of a person in a video or image with a different face while attempting to preserve the original person's facial expressions, head movements, and lip synchronization. In the context of accessibility, face swap technology has potential…

Fiducial Marker(also: AR Marker, Visual Marker, Reference Marker)

An artificial visual landmark placed in a physical environment to serve as a reference point for image processing systems. Fiducial markers — such as QR codes, ArUco markers, and BCH matricial markers — are designed for robust detection by cameras under varying conditions of…

Fintech(also: Financial Technology)

An umbrella term for software and digital-service innovations in the financial sector, including online and mobile banking, payments (e.g., Apple Pay, PayPal), budgeting apps, investment platforms, digital wallets, cryptocurrency services, and Buy-Now-Pay-Later products. Fintech…

Flexible Media(also: Object-Based Media)

A method of producing audiovisual media in which different components of the content (such as audio tracks, video angles, and subtitle layers) are stored as separate elements and assembled at runtime based on viewer preferences and needs. Flexible media enables individual…

Fuzzy Logic(also: Fuzzy Inference)

Fuzzy logic is a form of many-valued logic that deals with approximate reasoning, where truth values range continuously between 0 and 1 rather than being strictly true or false. In assistive technology and signal processing, fuzzy logic systems are used to handle imprecise or…
