Virtual reality headset

The virtual reality headset has a base unit configured for holding a portable computing device in situ via one of a plurality of magazines 102. Each magazine is configured for holding a differently sized portable computing device such as a mobile phone, cellphone, smart-phone or tablet. The headset also has a focusing unit 104 comprising at least two lenses 105 configured for focusing a screen of the portable computing device for a wearer of the headset. The focusing unit may be slideable in relation to the base unit such that the screen and lens are moveable toward and away from one another to facilitate focusing by the wearer of the headset (see figure 3). A friction lock mechanism using UV cured ink may be used to hold the magazine and base together.
