Field of view.
Wide field of view provides peripheral vision which enhances situational awareness and reduces simulator sickness. Narrow FOV forces users to use head movements in situations where eye movements usually suffices.
|
Up to 60° diagonal
(49° horizontal,
33° vertical) |
piSight 150-43b:
150° diagonal,
60° vertical
piSight 123-32:
123° diagonal,
45° vertical
|
Resolution.
Higher resolution throughout the visual field brings out fine detail in a scene, makes images look more realistic and increases the amount of information that can be displayed.

800x600 to
1280x1024 pixels |
Up to 4200x2400
pixels per eye. Most models have better than HD 1080p resolution. |
Image quality.
Look for displays that display bright colors, have high contrast and do not exhibit motion-blur.

Use LCOS or LCD displays. Refelective or back-lighting reduces contrast. Motion blur is often noticeable. |
OLED displays are self-emitting and do not require distracting front/back light. OLEDs are bright, have superior contrast and are many times faster than LCDs. They are also much more power-efficient.
|
Stereo overlap.
Larger stereoscopic overlap (the area seen by both eyes) enhances perception of depth and simplifies exploration and manipulation of near-field items.
|
Up to 49° |
Typically 72° |
|
Upgradeability.
Users of HMDs that can not be cost-effectively upgraded to wider field models risk finding themselves in a “technology dead end” once they realize that wider field of view is required or once needs change.
|
No. |
Yes! Cost-effective upgradeability throughout the entire Sensics product line. See our Frequently asked questions on HMD upgrades |
