Your application goal
Pen CharacteristicsPen “tip” identified by cursors
Same concept as mouse cursor
Pen can have multiple cursors
Some Tablets allow for multiple pen’s
Pen may have buttonsTip and first button simulate mouse
Supports up to 16 buttons
Cursor may have rich propertiesPressure, angle, etc.
EraserEraser
StylusStylus
Stroke
Represents a single Ink Stroke
Set of data captured in a single mouse down, move and mouse up sequence
ExtendedProperties – allows application to store any data on the Stroke
DrawingAttributes – controls the rendering of the Stroke
Rich API Points, Bezier Points, BoundingBox, PacketData
Top level object for handling ink (CoCreatable)
Attached to any HWND
Handles input from all attached Tablets and Cursors
Intercepts mouse movements and can draw Ink dynamically (default)
Three Ink Collection modesInk Only
Gesture Only
Ink and Gesture
Events – Stroke, Gesture, SystemGesture, more…
InkCollector
InkOverlaySuperset of InkCollector
Adds Select and Delete EditingModes
Cursor is changed and maintained by the InkCollector
Customizable by the application
Deleting Strokes – two EraseModes
StrokeErase – erase an entire stroke by passing the cursor anywhere over it
PointErase – erase segments of a Stroke
Selecting Strokes - lasso selection
Highlights selected Strokes by outlining them
DrawingAttributes
Controls the appearance of InkColor, width, transparency, smoothing, anti-aliasing
PenTip – round, rectangular, height, width
Can be scaled automatically using Renderer.Scale
Each collector has a DefaultDrawingAttributes property that specified the DrawingAttributes for all Cursors
Can be applied to a single Stroke, to a Strokes collection, or to a Cursor
What is a gesture? Anything you can do with a pen
Similar to keyboard shortcuts – e.g. ”Ctrl C”
System Gestures− Gestures supported by the Operating System by default
• To be notified subscribe to the ‘SystemGesture’ event• 14 gestures, examples: Tap, Double-tap, Drag
Application Gestures− Gestures your application can choose to support
− To be notified• Subscribe to the ‘Gesture’ event• Advise the platform of the specific gestures your app wants
−38 gestures, examples: Scratchout, Scroll up, Scroll down
−Gestures have confidence levels
Understanding Gestures
Allows recognition of a collection of Strokes by a specific Recognizer from the Recognizers collection
Synchronous recognition Call the ‘Recognize’ method
Asynchronous recognition Call the ‘BackgroundRecognize’ method
Subscribe to the ‘Recognition’ event
- or -
Call the BackgroundRecognizeWithAlternates’ method
Subscribe to the ‘RecognitionWithAlternates’ event
RecognizerContext
Controls• InkEdit
Super-class of Rich Edit control
Win32, .NET, ActiveX versions
Intended for text and ink-to-text scenarios
Works well in forms scenarios
• InkPictureSimilar to InkCollector
Allows ink annotations on images in .jpg, .bmp, .png, or .gif format
.NET, ActiveX version
Great for Forms
Great for easily adding Inking support into an existing app
Tablet PC vrs PC Applications Mice stay where you park them
Features requiring hover should have generous tolerances
For instance, tooltips
Bigger easily-targeted controls
User hand placement (menus etc)InkEdit Control should be big enough to write in
How will the user know the control is inkable
Don’t mix edit and inkedit controls
Recognition Expectations
Handwriting recognition is highly variable by person
Errors are expected
Perceived good or bad handwriting effects expectation of accuracy
GuidelineBe realistic about recognition accuracy rate, don’t rely heavily on it for authoring
Localization
Languages−Tablet V1
• US English, International English, Japanese, German, French, Simplified and Traditional Chinese, Korean
• Future – Spanish and Italian + others
• Extensibility architecture allows for custom recognizers to be built
