Tuhand

Tuhand is a term used primarily in speculative fiction and tabletop gaming to denote a palm- or forearm-mounted personal device that provides a portable interface for information access and gesture-based control. In most depictions, tuhands are modular and interoperable with other digital systems, functioning as a compact control platform for data retrieval, communications, and interaction with smart environments. The name often appears as an abbreviation or portmanteau related to hand-operated interface.

In narrative contexts, tuhands can range from slim bracelets to glove-like attachments and are typically activated by finger movements, palm pressure, or air gestures. They may offer features such as wireless connectivity, encrypted communication, biometric authentication, augmented reality projections, and tactile feedback. Some stories treat tuhands as ubiquitous consumer technology, while others reserve them for specialized roles such as field researchers, engineers, or security personnel.

Historically within fictional settings, tuhands emerge from rapid advances in microelectronics and wearable sensing, becoming central to themes of privacy, autonomy, and human–machine convergence. Debates within fiction often focus on access disparities, data sovereignty, and the political implications of pervasive hand-held interfaces.

Because tuhands are not an established real-world technology, references appear in creative works, role-playing game material, and fan wikis rather than peer-reviewed literature. See also: wearable computing, augmented reality, human–computer interaction.
