If you are a wildlife filming enthusiast or a keen bird watcher, it may do you well to focus attention on Google’s latest invention – the Google Glass Binocular. This is the second part to its invention of the first version of its binocular series assuming that a third version will be in the offing after this one. The special feature of this second version is its Head Mounted Displays or dual eye displays.
The “HMD” as it is now referred to, is normally worn atop the head or close to it for maximum effectiveness. What’s so amazing about the HMDs is they sport a type of optical system that’s located a few centimetres from the eye. The display system has two distinct eye displays, one called the monocular HMDs and the dual eye imaging displays known as the binocular HMDs.
The two HMDs are divided according to their function and purpose with some models that can produce an image canned a computer generated image or “CGI”. Other models are capable of superimposing a CGI image on top of a natural world view. In the case of the latter, the viewer gets a special display treat with the real world image enhanced by the CGI image on top. Some refer to this display as a “heads-up” display or HUD.
One important feature of the HMDS is they can be applied for practical purposes or for leisure. When applied to aeronautic use, they enable pilots to have a full and clear visual view of vital control information for a flight without losing sight of the plane’s flight direction. For public safety, the HMDS provide map displays plus thermal imaging. They can also be applied to video games, transport and telecoms.
The technology is a novel invention and there are bound to be more applications in the area of practical and leisure use that may emerge in the future. For now though, expansion to wider fields appear restricted because of size, extent of view and the effectiveness of systems now used for deploying MHDs. Also there is the question of technological issues that need to be solved before the device can be generally welcomed into the market.
Deformation is one of the major issues that can result in a harmful misalignment of the left and right image displays of the binocular HMD. The event will produce an unclear image of from the user’s perspective which of course detracts from clear viewing that the user expects. Blurred images may occur from a variety of reasons such as misuse, poor use or thermal warping that result in a poor view of facial features.
There are also other issues relating the size of the user’s head or the placement of the ears. In the first instance, the narrow head would exert force on the two arms of the binocular HMD which can cause a spreading force to the ear arms. A narrow head would also force the ears to compress inwards which in turn may twist the left and right sides of the binocular HMD.
In respect of this invention, there is a lot of room for improvement but no doubt with other brands joining in, the only possible outcome from the competition would be higher quality and a user friendly binocular.
