Slide-on HMD
Slide-on HMD, also known as Smartphone mount, is the cheapest and most accessible form of virtual reality head-mounted display. The Slide-on consists of a smartphone holder, lenses and some form of basic input. A smartphone is inserted into the HMD and the entire device is played upon the eyes of the user to create the VR experience. The Slide-on utilizes the smartphone for display, processing and rotational tracking. Some Slide-on HMDs such as the Gear VR use their own built-in IMUs instead of relying on that of the smartphones. This method allows the HMD to create a superior tracking experience for the user.
Slide-on HMDs are often the cheapest form of VR if the user exclude the cost of the smartphone. Google Cardboard can be built or purchased for under $20 and Samsung Gear VR can be purchased for $99.
