koskettavuuteen

Koskettavuuteen is the illative form of the Finnish noun koskettavuus, a concept that refers to the quality or capability of being touched, perceivable by touch, or accessible through contact. In Finnish grammar, the illative case (-uun/-eene) marks direction toward or into something, so koskettavuuteen is used when the discussion centers on tactile aspects or touch-related considerations.

Koskettavuus as a concept can denote tangible properties of physical objects, such as texture, roughness, temperature, and overall tactile feedback. It is also used in a broader sense to describe contactability or the ease with which something can be interacted with through touch. The illative koskettavuuteen appears in sentences that address focusing on or aiming toward tactile aspects, for example in design or accessibility discussions.

In design and human–computer interaction, koskettavuus is an important criterion for usability and user experience. Designers may strive to improve koskettavuuteen by enhancing tactile cues, such as button feedback, material texture, and labeling that can be sensed by touch. In accessibility contexts, attention to koskettavuuteen helps ensure that devices and products are usable by people who rely on tactile information, including those with visual impairments.

Related terms include kosketus (touch), kosketettavuus (tactility or tactile accessibility), and haptics (tactile feedback). The concept of koskettavuuteen thus appears across linguistics, design, and accessibility discourse as a way to discuss or direct attention toward touch-related properties.
