Increasing FOV in displays

BIGGER

Sometimes a bigger field of view is more important than a wider field of view

Projection on the environment is considered a Gold standard - perfect registration

Width is the metric people use - people want wider FOV

But there are many applications when height is the issue

Eg: - walking downstairs with low vision - not a context when using a cane makes sense

FASTER

Decrease latency

The time btwn stimulus (cause) and response (effect)

Eg: motion to photons
— Motion can be head, hands world

Most electronics in our environment are more than 100 milliseconds delay

Some are 10 milliseconds

Perceptible Latency (university of Toronto) 1ms-latency 2D touch screen 2013

Around 6 milliseconds is noticeable (in a random group of people - not a group selected with high reflexes - eg athletes, race car drivers, pro gamers)

OUT OF HANDS

Context without hands

Eg Hands-free AR for vascular intervention

Both hands are busy with a catheter -
Using Headpose & voice

[See video]

Scaling and rotating based on head pose
Increase rotation and rate of rotation by moving head away from virtual object
Change location by head pose

This is also important for accessibility

Importance in many domains of not using hands at all,
