Here are some basic guidelines that we recommend you to follow when presenting using Virtual Reality:
- It is hard to get a correct sense of scale in sparse environments. Therefore, it is better to limit the size of the presentation material to a smaller area, rather than having a larger presentation that might feel empty and deserted. While this may not seem to be of significance, a less decorated scene could strike the viewer as dull or abandoned.
- Keep in mind that Virtual Reality might have a strong impact on the viewer. Avoid creating tightly confined spaces, large drops in height, spaces without walls or too dark areas as such experiences could be disturbing to some. Viewers suffering from Claustrophobia, Hypsiphobia, Agoraphobia or Achluophobia might be very uncomfortable if exposed to such environments. Always ask about any of these conditions before having a viewer wear a headset.
- Add some visual landmarks to the drawing; some places that the viewer can easily recognize. Avoid repetitive scenery as this will disorient the viewer.
- Avoid wallpapers and materials with small stripes or fine details as this could cause optical illusions that might distract the viewer from the presentation itself.
- In current Virtual Reality technologies there is a phenomenon known as the screen-door effect. This refers to the viewer becoming aware of the individual pixels in the headset. This effect becomes more noticeable in bright environments and can be avoided by using darker colors and materials.
