The small displays of smartwatches make text entry difficult and time consuming. While text entry rates can be increased, this continues to occur at the expense of available screen display space. Soft keyboards can easily use half the display space of tiny-screened devices. To combat this problem, we present Invisiboard: an invisible text entry method using the entire display for both text entry and display simultaneously. Invisiboard combines a numberpad-like layout with swipe gestures. This maximizes input target size, provides a familiar layout, and maximizes display space. Through this, Invisiboard achieves entry rates comparable or even faster than an existing research baseline. A user study with 12 participants writing 3264 words revealed an entry rate of 10.6 Words Per Minute (WPM) after 30 minutes, 7% faster than ZoomBoard. Furthermore, with nominal training, some participants demonstrated entry rates of over 30 WPM.
