Abstract
A sensing apparatus for use in combination with a stationary bicycle comprises a housing that supports a source of emitted radiation and a detector of radiation of the same wavelength as that emitted by the source, fixing means for fixing the housing to an exercise device such that radiation is emitted towards a region of space that can be occupied by a part of a body of a user of the exercise device and selectively transmitted on to the detector depending on whether a part of a user's body is located within the space, a processor which measures at least one property of the radiation from the source that is passed to the detector and from the measured property produces an output signal indicative of the proximity of the user relative to the device within that space.
