A mouse includes an aperture defined in its top, a light source, and a data processing unit partially positioned external to the housing from the aperture. When the mouse is covered by a palm of a user and the light source emits infrared light, the infrared light reaches the palm of the user through the aperture, and some of the infrared light is reflected and received by the data processing unit. The data processing unit calculates and measures the heart rate and body temperature of the user against physiological parameters.
