Development of embodied visual effects which expand the presentation motion of emphasis and indication

Although visual presentation software typically has a pen function, it tends to remain unused by most users. In this paper, we propose a concept of embodied visual effects that expresses emphasis and indication of presentation motions using a pen display. First, we measured the timing of presentation motions of pen use achieved while in sitting and standing positions. Next, we evaluated the timing of underlining and explanation through a synthesis analysis from the viewpoint of the attendees. Then, on the basis of the results of our measurements and evaluation, we developed several visual effects. These visual effects, which express the embodied motions and control the embodied timing, are implemented as system prototypes.
