You can test whether a website is usable by making wire frames, but how do you know if that site, product, or store is emotionally engaging? We build quick, iterative environments where emotions can be tested and improved. Emphasis is on setting up the right motivation (users always have to buy what they pick), pressures (can you buy the laptop in 10 minutes?), and environment (competitors� products better be on the shelf too). Once we see where customers are stressed or miss the fun part, we change the space on a daily, iterative cycle. Within two to three weeks, we can tell how to structure a new offering for a great experience. Seldom do the emotions we hope to create happen on the first try; emotion prototyping delivers the experience we want. We hope to better understand the benefits of emotion prototyping, especially while using the skin conductance sensor.
