Although the Mountain View Company cannot guarantee that body electrodes will be an integer part of the testing process, Google informs that the participants will be financially rewarded for their involvement. By completing online surveys or by actually spending time on a Google researcher, testers can get up to $75 an hour while the duration of a study normally doesn't extend past one-and-a-half hours. The studies will focus on evaluating existing and developing Google products, via customer feedback.

"In user studies and field studies, you will typically spend one to one-and-a-half hours with a Google researcher. For each study, we need to make sure that we invite people who match our target user profile for the product we are researching. We also want to get a good balance of ages, backgrounds, and levels of experience, so please be honest with your answers. It's easier for us to match you to a suitable study when we have more information about you, so if you fill in as much of our sign-up form as you can, it's more likely that you will be invited to participate," informed the Mountain View Company in a FAQ related to the Google User Experience Research.

Participants can sign up for four types of studies: usability study at a Google office, remote usability study, field study and online survey. According to Google, the paycheck will vary in relation to the tests performed.
