Because goal of our design is to help people relieve stresss, the age range of between 20s to 30s fits the best. They are both familiar with technology and we can draw two different kinds of reaction from them. For the technology aspect, almost non of them would have problem in adapting to the interface. As persona #1 has extrovert characteristic, he/she would easily approach the wall and enjoy it. The #2, who has introvert characteristic is also likely to appreciate the wall as they can interact comfortably with a “buddy” .
