'Human in the Loop Research Project' lab opportunity

I work in a lab and we are actively recruiting participants at this time. Bellow is a short description of the lab along with the link to sign up:

I am apart of a research group called the Human in the Loop Research Project and we are in need of participants for our study! We would greatly appreciate if you could join us on campus to participate in a roughly 30 minute experiment (and maybe come back for repeat studies!). We would love to have you!
A little background on the experiment: Your task is to use a handheld device that is equipped with pins on the bottom, which you will need to compress to 50%. The way that you will know you have completed the task is by various frequencies of vibrations and, at times, sound. This will be repeated a number of times.

If you are interested, please request a time to sign up by using this link to our website: https://sites.google.com/email.arizona.edu/humanintheloop or by contacting me directly. 
We currently have 20 facilitators and can accommodate most times during the day!
Even if you cannot participate, we greatly encourage you to spread our website around to anyone that may be able to! By participating and spreading the word, you are helping further scientific research and helping to provide research experience for students.

Thank you so much for your time!

Sincerely,
Michael Cardenas
