Marking Menus Pen-based radial
menu that allows users to select options based on direction of movement
Easy for novices and beginners
Faster to perform
3
Long Term Study Two users: one expert, one novice
annotated conversation data over a month
How else might the study have been done? How do marking menus compare to
context menus with keyboard shortcuts? Was there a non-marking menu way to
accomplish the tasks (hotkeys)?
4
Menus in the real world Many things are
still linear menus – barriers to adoption?
Pie Menus (in Denim, the Sims)
Alias | Wavefront Others?
5
T3 Prototype (Old) Tablets, Two-
Hands, Toolglass Allow independent
movement of toolglass and cursor
How would you make these features self-revealing? They say training
covers all
6
StudioPaint Dropped Rotation-
aware widgets Is this an issue?
Better Sweeping Have mix of GUI and
new input styles Would users be
interested in adopting T3 as it was or as it is in StudioPaint?
7
T3 Today
Tablet PCs are now in (not Wacom) Is two handed input that important for
drawing apps? Is there bimanual interaction with
a Tablet PC? Maybe give it a sensor that measures
orientation and attitude?
8
Real-World Interface Props Use passive props to
allow expert users (neurosurgeons) to manipulate a familiar object which controls a computer representation
As opposed to abstract gestures on virtual objects
9
Extending Props Props clutter the real world? Can you be precise with props? What are props good for? Only for
interacting with a 3D model? Can you make generic props (one
sphere, one cube, one plane, one line) and remap per application?
What about props versus haptics? Is it the difference between passive and active?
10
Future Gestures Minority Report -
Video manipulation John Underkoffler
(Media Lab) A consistent
language for gestures seems to exist in the clip (copy, zoom, frame)
Johnny Mnemonic – Navigation on the internet
11
Gestures versus Props
When are gestures used? When speaking … “I once caught a
fish…” Hard to specify precise quantities Most of the time our gestures aren’t
under our exact control. So when would it be useful?
Gesture versus direct manipulation?
