Presentation Transcript

  1. Gestural and Bimanual Input Doantam Phan CS 376 Discussion

  2. 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?

  12. Brainstorming • Choose gestures, props, bimanual input (or all of them!) • What is a good use for them that isn’t one of the papers we read?
