Head Mounted Displays (HMD)

How to take advantage of the benefits of a head mounted display

Both the commercial uses for head mounted displays (HMD) and the refurbished HMDs used in gaming and entertainment are enough reason to justify the over-the-top marketing that has been swirling through the HMD market. In addition, there are certainly some beneficial uses other than recreation for HMDs, including medical head mounted displays for work in telerobotic surgery and psychological treatment of phobias. However, there are safety issues to keep in mind.

When working with near-to-eye displays, whether you are considering purchasing or selling HMDs, you need to consider the InterPupillary Distance (IPD) on your head mounted displays. For example, children will require a significantly lower IPD measurement for HMDs than will adults.

Consider these steps for adjusting your HMD:

1. Practice proper use of HMD. If you normally wear glasses, keep them on to allow your eyes to remain focused.

2. Adjust your HMD to rest against your forehead, not on your nose.

3. Adjust the lenses on your HMD to be parallel with your eyes (read your manual’s instructions for aligning the eye piece with your IPD). This is important for children because misalignment may cause visual impairment. Children should not wear the HMD for prolonged periods of time.

Purchase a head mounted video display

Head mounted computer displays are available in quite a large variety, so you will want to know something about the product specifications you need before you invest in a head mounted video display or head mounted TV display.

Virtual home theater isn't a thing of the future. Just a click away from reality is a home theater HMD about which gadget enthusiasts are excited.

Use head mounted displays for training and safe practice

Some of the benefits of virtual reality are overlooked. The benefits of training people before they enter dangerous or hazardous jobs are enormous when using head mounted TV displays. Initial training done in VR wearing head mounted video displays can actually save lives by preventing real life disasters. Remember, it is OK to make a mistake in a VR test, but an error in real life hazardous work could be deadly to your employees.
