Abstract
Text entry on head-mounted wearable devices is often constrained by compact interfaces, leading to slow or inaccurate input. To address these limitations, a segmented touchpad interface is provided on the temple of the wearable device. A traditional keyboard layout is split into four distinct regions, which are mapped to four corresponding segments on the physical touchpad. Each segment is configured to represent multiple characters, and text is entered through a sequence of taps on these regions.
Linear swipes along the touchpad are utilized to replicate rotational input for selecting suggestions, while long-presses and glides enable character selection from pop-up menus. Tactile splitters or varying surface designs are incorporated between the touchpad segments to improve spatial awareness for the user. This system provides a more intuitive and efficient text entry mechanism for compact wearable interfaces by utilizing familiar input paradigms adapted for a touch-sensitive surface.
