One important factor related to these dimensions is spatial memory.…”

LightMeUp: Back-print Illumination Paper Display with Multi-stable Visuals

“…Displaying animated images, video explanations, and real-time visual feedback was shown to improve task execution [39]. The combination proved successful also in collaborative content production using multi-layer digital information annotations [59,82], and enabled dynamic work-spaces such as displaying and modifying data on a blueprint [63].

“…However, such modification requires to purposely and individually develop and prepare each sheet of paper. Some approaches are based on projecting digital information on or around paper with a front projector [14,35,37,63,76], which needs an elaborate setup to avoid projected light to be occluded by users and consequently impact user experience. Other solutions are based on placing displays on top or above the paper creating a "magic lens" that reveals additional information in relation to content on paper [41,52].…”

VersaPen

“…To achieve this, various input modalities have been considered such as tilting, rolling [26], shaking [24] the device, as well as pressure [19], grasp [21], nearsurface interaction [17], speech recognition (LiveScribe) or just using an additional scroll wheel (Wacom Air Brush). Previous studies also considered different output modalities, such as visual feedback (using LEDs [16], embedded screens or projectors [22]), audio feedback or haptic feedback [14]. These technologies propose new pen-based interactions, but each one requires a specific device and works with prototype applications.…”
