Abstract

In modern society, it is common to display advertisements on large displays installed in public spaces such as stations and libraries. However, with in a limited size of display, it is difficult to provide different information simultaneously and smoothly to multiple viewers with different viewing distances.

Problems with digital signage. If people near you display detailed information, people far away will not be able to see the summary information.

In our research, therefore, we pay our attention to an existing method that adopts the concept of hybrid-image, in which the visual content is switched according as viewing distance to the display. Then we propose a new method for displaying interactive buttons on he display as part of the hybrid-image so that viewers are allowed to find information they want more easily. In addition, we develop the authoring tool HYDRO (HYbrid image Display Resolution Optimizer) with two kinds of optimization functions for Digital signage. The visual effect of the optimized generated images was empirically conrmed. 

Hybrid Image

HYDRO has two optimization functions. One is a function that optimizes the arrangement of widgets (buttons) that are displayed to viewers near the other, and another is a function that optimizes the resolution set so that the images viewed at a specified distance are switched. In addition, the evaluation experiment was carried out using the content produced by HYDRO, and the effect was verified.

Interface of HYDRO (HYbrid image Display Resolutions Optimizer)

HYDRO and SAM(Smart Ambient Media)

HYDRO has the flow of outputting the state requested by the user by touch panel operation or setting by the user and presenting it to the user. In other words, because it has the flow of Human-in-the-Loop, which is the core concept of SAM, it is positioned as SAM.
