Softkeys will act exactly as they will in the final application. Data collection can be a challenge. Most usability tests record the user s body language and interaction with the product using two cameras. These videotapes are useful for the product team to understand how users are reacting to their product. However mobile devices are intended to be held. The best solution to the problem is to put the device on a sled. The sled has two cameras one pointing at the device face and the other pointing to where the user s face is if the user is looking at the device. This allows the device to act very much as if there were no cameras at all while allowing the researcher to use most of the same tools as she would if it were a computer usability test. As always it is best to match the device used in the usability test with the type of device the participant typically uses.
