There are also variations of the pedal controller such as the proposed rotating pedal device for a cycling game, which relies on an ergometer to generate user inputs such as pedal rpm and pedal resistance.[6] A variation of this concept surfaced in 2016 when a startup called VirZoom debuted a set of sensors that can be installed in the pedal and handlebars, turning a physical bike into one controller for games on the HTC Vive and Oculus Rift virtual reality (VR) platforms.[7] The same concept is behind a product called Cyber ExerCycle,[8] which is a set of sensors attached to the pedal and connected to the PC via USB for bicycle simulation games such as NetAthlon and Fuel.
