Virtual reality
Around the same time, Douglas Engelbart used computer screens both as input and output devices. In 1968, Ivan Sutherland, with the help of many students including Bob Sproull, created what was widely considered to be the first head-mounted display (HMD) system for use in immersive simulation applications. It was primitive both in terms of user interface and realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire-frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles.
Hedgehog Lab
After seeing growing interest in Virtual, Augmented and Mixed Reality, hedgehog lab invested in its own Immersive Technology division, equipped with state-of-the-art kit to develop for headsets like Oculus Rift, HTC Vive and Microsoft HoloLens. Launched in January, 2017, this is being headed up by one of the UK's leading experts, Shaun Allan, who has many years’ experience in the field, and whose VR pitch recently helped the North East region win the bid to host the Great Exhibition of the North.
