A wristwatch-sized display is the smallest design space out of all the endeavors WOW has ever set out upon. There were also a variety of difficulties in displaying on electronic paper – a platform without many comparable prior examples. However, we continued directly working with programmers to investigate the novelty of images moving around the panel, the timing to switch screens, and depth of images visible on the tiny display. Through patient exchanges between designers and programmers continuing the search for optimal solutions, we made it possible to incorporate expressions so that the user feels a sense of “time” through visual imagery. This model is equipped with three different modes: “Factory and Fantasy Mode” – which optimizes enjoyment of a new world environment, “Clock Mode” – which provides for a simple way of telling time, and “Desktop Mode” – which allows for manipulation of the direction of characters as well as temperature display.
