Abstract: A virtual reality (VR) system comprising a head-mounted display (HMD) and handheld controller set is enhanced to provide a more realistic end user VR experience. According to this disclosure, a chroma-keyed trainer is embedded in the VR environment for use in workouts. This creates the illusion that the trainer is with the user in the virtual room. To create this effect, the trainer is filmed using a chroma key setup (e.g., a green screen background) and with standard cameras. The video is used in the headset with the keyed color (green) removed. As the training video is rendered, a set of virtual reality (VR) events that have been synchronized to movements of the trainer in the training video are output to the user so that the trainer actively participates in the workout with the user.

Abstract: An apparatus (1) for restricting the bending of a tubular member underwater comprises a plurality of interlocking modules each formed from a first half shell component (2) circumferentially displaced from a second half-shell component (3), wherein the first half shell component comprises one or more projections (19) extending from a side edge (18) thereof and the second half shell component comprises one or more grooves (21) in a side edge (18) thereof, the projections and grooves being angled to the side edges of the first and second half shell components, the arrangement being such that when assembled together each of the one of more projections of the first half shell component are inter-engaged with a corresponding groove of the second half shell component to secure the two half shells together.
