This study investigates the ability of a special camera, called the PhysioCam, to detect tiny changes in blood vessels on the face, known as vasomotor activity. The PhysioCam's data will be compared with other sensors to ensure accuracy in capturing these changes.

Participants will undergo procedures where their physiological data is gathered using the PhysioCam and other sensors. This will help verify the camera's effectiveness in detecting vasomotor activity.

• Who can participate: Participants should not be taking medications for heart conditions or blood pressure, have a pacemaker, or have been recently hospitalized for head injury or major surgery. Those with allergies to certain foods, prone to skin reactions, or with dietary restrictions that would impede them from consuming potato chips should not participate.
• Study details: Participants will have their physiological data collected using the PhysioCam and other sensors. The study does not offer compensation for participation.
