Gestareikningar

Gestareikningar is a term used in Icelandic to denote the idea of performing calculations through gestures. The word combines gest, meaning gesture, with reikningar, meaning calculations or accounts. In practice, gestareikningar describes methods where hand movements, body pose, or other non-verbal signals are interpreted by a device to carry out arithmetic operations or to control computational processes. This concept sits within the broader fields of gesture recognition and human–computer interaction and is sometimes discussed in the context of educational technology and accessibility.

In application, gestareikningar can involve controlling calculators or math software through gestures, enabling input for users with limited motor function, or creating interactive learning environments where students express numbers and operations through pose. Technical approaches rely on devices such as cameras for computer vision, depth sensors, inertial measurement units, and microphones, paired with machine learning models to map observed gestures to digits, operators, or commands.

Challenges for gestareikningar include ambiguity and variability in gestures across users and cultures, the need for reliable calibration and personalization, latency and energy efficiency, and privacy considerations when sensing movement. The term appears mainly in experimental or speculative discussions rather than as a standardized topic in mathematics or computer science, and it is often treated as a subset of gesture-based interfaces rather than a distinct, established discipline.
