Katseenkäyttöaikaa

Katseenkäyttöaikaa is a Finnish term that translates literally to “time of display usage” or “screen time.” It refers to the duration during which a visual interface—such as a computer monitor, television screen, or mobile device—remains active and visible to a user or audience. The concept is used in both consumer electronics and media studies to describe how long a display is engaged, either by a single individual or multiple users in a shared environment.

In the field of human–computer interaction, katseenkäyttöaikaa is a key metric for evaluating user experience and interface ergonomics. Designers of software applications and websites collect data on screen time to assess engagement levels, optimize content placement, and reduce cognitive load. Likewise, television broadcasters use the term to analyze audience viewing habits, informing programming schedules and advertising strategies. In educational contexts, schools monitor katseenkäyttöaikaa to ensure that students are not subject to excessive screen exposure, aligning with health guidelines on eye strain and sleep quality.

The term is increasingly relevant as digital devices become integral to everyday life. Organizations such as the Finnish Institute for Health and Welfare advise that adults should limit everyday personal screen exposure to no more than six hours, while children under six should have no more than one hour. Monitoring and managing katseenkäyttöaikaa therefore plays a significant role in promoting healthy digital habits and well‑being.
