Outcome

Problem:

In studio based environment, sometimes, it is hard for a group of brilliant team members to make decisions on their next step direction. Most of the time people use methods like weight matrix, group vote or just endless discussions. But they are not efficient and will take lots of time. Also, people may get influenced by other team member.

Solution:

Votee is a voting system that can help “designers” to gather ideas within studio quickly, efficiently and quantitatively.

What is Votee?

Votee is a collaborative voting system which helps users in group study to make decision and choose ideal proposals. It is easy to vote . It is Votee.

Working

This system has two connected parts. One is voting boards for users. In the studio based study or group meeting, each student has a voting board with several buttons on it which represent different proposals. The other part is a big display board. It will be placed in the public places in the studio or classroom and shows the voting results. The lightness in each grid represents how many people agree this proposal. By comparing the lightness of each proposal users can make decision easily and quickly.

We further envision the icon elements. Users can use these icons to tell a simple story or describe each proposal.
