Faster drawing using the “Design prediction” feature.It predicts what you will draw next and automatically selects the right tool for you

Auto introduce design elements whenever its necessary. Draw a connector, it automatically adds the right symbol

Sketch Recognition

Basic ArchitectureBasic Architecture

Generic Geometric Shape Recognizer

Parser

Context specific Symbol Recognizer

This layer works with UI. It collect strokes in buffer and pass to parser layerDrawing Board

A parser can have input strokes in UI dependant format and convert it to a generic stroke format

A Shape Recognizer recognize the basic geometric shape from input strokes (i.e. Line, triangle ... )

A Symbol Recognizer detects a context specific symbol from a collection of basic geometric shape. For ex: a UML Symbol Recognizer will detect ‘Note’ if the basic shape is Rectangle and context is Use Case.

Drawing BoardDrawing BoardA drawing board is a place where user can draw freehand diagrams using pen interface.

The drawing board collects the user strokes using Microsoft Table PC ‘s Ink interface. After a certain interval it passes the collected strokes for detection. For use case diagram, it passes the collection when ever a stroke is generated.

10

ParserParserThis is the first layer of sketch recognition. It converts the input data (i.e. strokes) to a common format ( Point array ) which is compatible with other layers.

By replacing only this Parser layer the recognition layer can be reused in any other purpose.

Detecting a SymbolDetecting a SymbolThis layer detects the basic geometric shapes from Point array. For multiple strokes, it will be an array of Point array

Recognizing basic Shapes

Basic Calculations:Length of a stroke = sum of distance between every two points

Length of enclosed rectangle [(height + width) x 2] = LER

Ratio of ( lengthOfStroke / lengthOfConvexHull ) = Lsc

Ratio of ( Area of Convex Hull and Enclosing Rectangle) = ACE

PerimeterOfEnclosingRectangle = PER

XUML Persistence

XUML OverviewXUML Overview

XUML = XML for UMLNew human readable application independent generic format named “XUML”Easier for XML Transformation using XSL in order to build custom import/export to other formats. For ex, Rose XMISupports first ever “XSD” validation technique for dynamic UML syntax and semantics checking.

Distributed Command Pattern

Distributed Command PatternDistributed Command Pattern

Executing same command in same process, out-of-process, and over the network in another running processIt is used to perform the same action on multiple running application producing the same result in each applicationFor example, in a chat server, if one client sends a message, it shows the message on its own screen and also on all the clients connected to the same server
