System and Method for Contactless Sensing on a Treadmill

A method, comprising:

• receiving, by a first sensor of a treadmill, a first reflected signal that is a first reflection of a first radar beam reflected from a user on a belt of the treadmill;
• receiving, by a second sensor of a treadmill, a second reflected signal that is a second reflection of a second radar beam reflected from the user;
• generating, according to the first reflected signal, first data associated at least one of a gesture of the user or a position of the user on the belt;
• generating, according to the second reflected signal, second data associated with a vital sign of the user;
• controlling at least one of the belt and a display of the treadmill according to the first data;
• and
• displaying, according to the second data, the vital sign on the display.

A method, comprising:

• moving a belt of a treadmill;
• transmitting a first radar beam over the belt toward a user on the belt while the belt is moving;
• detecting a first reflected signal that is a first reflection of the first radar beam from the user;
• generating, according to the first reflected signal, first data associated with a vital sign of the user;
• and
• displaying, according to the first data, the vital sign on a display of the treadmill.
