Equipment & Lab: The sensor used in our heart rate assessment attaches to your earlobe via an ear clip (see images below). The device will then be secured to your arm using an arm band and connected to a laptop for data collection.

Our lab space is located in the IU Intelligent Systems Engineering Multidisciplinary Engineering and Sciences Hall (MESH). The study room is accessible by those with limited mobility and close to accessible private restrooms. We will provide you with different lighting options too choose from based on your personal preference.

Procedure:

1. Upon your arrival, an assistant will meet you at the door and provide you with a parking pass.

2. You will complete a COVID-19 screener before going to the lab.

3. The assistant will describe the study, walk you through the consent process, and answer any questions you may have.

4. Upon consenting, you will first complete a survey about your demographics and psychological wellbeing. All data will be protected and accessible only by the research team.

5. The assistant will then guide you through the heart rate assessment during which you will be cued to move into 3 postures for 3 minutes each: lying down on a cot, sitting up in a chair, and standing.

6. Afterwards you will remove the device and all equipment will be sterilized.

   Note: You will be able to withdraw from the study at any time for any reason.

Study & incentive Schedule: The study will consist of three heart rate assessment sessions: Before your SSP participation, 1 week after SSP participation, and 4 weeks after SSP participation. There will be a $25 Amazon gift card incentive for completing each assessment and an additional $25 bonus if all 3 visits are completed (an opportunity for $100 total).

Clothing: While you are welcome to dress whatever way you like, we do recommend wearing comfortable clothing. We also suggest wearing pants or shorts since you will be lying down. Additionally, our study room can be slightly chilly at times, so a light jacket and pants are also recommended.

Since our PPG device will clip onto your ear lobe, we also advise that you avoid wearing earrings to your assessment. For people with gauges or irremovable piercings, we will work with you to find another part of the ear to measure from.

Location: The IU Intelligent Systems Engineering Multidisciplinary Engineering and Sciences Hall (MESH) is located just north of the IU stadium at 2425 N Milo B Sampson Ln, Bloomington, IN 47408.

The sign at the entrance to N Milo B Sampson Ln will have a sign that says ‘Technology Park North’.

Parking Instructions:

1. After turning onto N Milo B Sampson Ln, continue past the 3-way stop and all the way through the long parking lot on the east side.

2. Continue to the back of the building and park in the designated areas north of the building (see map). Visitor parking is marked with a black sign with a ‘V’.

3. An assistant will meet you at the entrance (see below map) and provide you with a parking pass for you to place in your car.

Note on Cell Phones: Cell service in our building is very limited. If you need to contact an assistant, please use email to get in touch with us. Additionally, if you need to text or call, communicating through Wi-fi or stepping outside will work best.
