PRE-TOUCH SENSING
TOUCH IS
ANALOGand
CONTINUOUS…
IF NATURAL HUMAN
(x,y)
Then why do we boil the
down to flatland?entire vocabulary of mobile touch
Much of what characterizes ‘touch’ startsbefore contact
and originates
beyond the confinesof the screen.
AN INSTANT IN TIME…FROM TOUCH AS A POINT,
TO A WHOLE WORLD THAT SURROUNDS IT…
This treasury of contextual detail—
the combination of hover and gripthat we collectively refer to as
pre-touch—has been lost to mobile interaction.

You’ve probably heard about hover, or seen examples of control gestures in-air.

what happens before, the framing, the context.

We explore an emerging modality, breadth-first across a number of

INFORMALEVALUATION
and they’re predictive.”
“feels very natural to my hand,” allows
– adapt to hand size?
Ad-lib interface (video player)
“I like the transparent controls,
“a single hand in a comfortable position.”
– controls should appear more quickly?
– per user adaptations may also be helpful
Overall
– The one-handed adaptations stood out
– But all techniques had proponents
– Ballistic vs. fine taps: great for some users,
– current heuristic doesn’t consider grip.– not so much for others.
CONCLUSION
CONCLUSION
Pre-touch holds great promise for fresh approaches to many challenges in mobile touch
interaction.
Our work has only just begun.
