1. Scribbles
Jim Li Roy Lim Matt McKenzie Anthony Wu

2. Motivation for Scribbles
Pen input requires a different approach to correction (vs. MS Word style editing)
What you write is what you get but we want the ability to correct simple & common errors
We want to bring these enhancements to Tablet PC handwritten documents

3. Goals
To provide a “natural” interface for typical corrections (i.e. delete, insert, overwrite)
Mimic common correction conventions with pen and paper (i.e. grading)
To incorporate selected enhancements from word processors

4. Editing Features Insertion by “carrot” (^) indicator
Deletion by crossing out replacing word
Letter overwrite
Moving block of words by selection and drag
Automatic text rearrangement such as line wrapping
Auto-sizing edit strokes to fit text
Able to save note

5. Mockup – “Incorrect Input”

6. Mockup – “In Edit Mode”

7. Mockup – “After Correction”

8. Possible Extensions Undo/Redo Editing
Line alignment (left/center/right/justified)
Swapping Words (  )
Spacing Mode (single / double spacing)
Bold/Italic/Underline
Calculate and auto-enforce uniform word spacing
Spelling auto-correction in users’ handwriting

9. Risks / Difficulties Editing Stroke Recognition
Line Wrap (line spacing, paragraph)
Calculation of Stroke Segment Properties
Inconsistent User Input
Lack of time for extensions

10. Milestones Early Prototype – Feb 3 First Risk Evaluation – Feb 10
Notepad interface
Ability to make editing marks
Complete plan for modular code design
First Risk Evaluation – Feb 10
Alpha – Feb 22

11. Milestones (continued)
Second Risk Evaluation – Feb 28
Project Completion – March 10
Provide distributable executable
Possibly some of the extensions implemented
General polishing of application
It works!
