The voting system introduced on the page of the collaborative design support system, but We found a serious problem while proceeding with the research. It's surprisingly difficult to get the number of votes.This system assumes that users will actively vote, so the design will not evolve unless the number of votes. To solve this problem, we proposed a system in which designs are displayed on digital signage in the city and people can vote on the spot, as shown in the figure below, but the process of stopping and voting (i.e., pushing the voting button) seems to be annoying, and it was difficult to get votes.


Although these systems have achieved some results in the evaluation experiments, we think that further improvement is still necessary.

For improvement of the system, we are verifying the use of gaze information. When using digital signage, if each user just stops and looks at the design instead of voting, or also looks at the design while walking. We would like to build a system that applies the real environment.

The figure below is an overview of the system that creates character coordination based on the gaze information of multiple users.


In this system, the characters appear in various coordinates and move for about 10 seconds. During that time, multiple users can freely view the character, and the system evaluate the coordination based on the gaze information at that time. The design parts used for coordination are as follows.


The coordination evaluation of this system uses the winning paired comparison evaluation method introduced on the page of the men's watch design system, and the winner coordination is determined by the gaze information of multiple users.

We confirmed various effectiveness from the results of evaluation experiments that even if some of users in a group partially participates in a round evaluation for a series of round evaluations, the system can generate a satisfactory design to group of users.
