• Speech Synthesis • AR Parrot Drone UI• 3D printing

Agenda

Speech Synthesis

• XML based language• W3 standard for speech synthesis

Speech Synthesis Markup Language (SSML)

• Mark• Notify app that certain point has been reached

• Phoneme• Phonetic pronounciation

• Say-as• Aid the synthesis processor

• P, Break, …

// create the data streamSpeechSynthesisStream synthesisStream; synthesisStream = await this.synthesizer.SynthesizeSsmlToStreamAsync(text);

// start this audio stream playingthis.media.AutoPlay = true;this.media.SetSource(synthesisStream, synthesisStream.ContentType);this.media.Play();

AR Drone 2.0

Initialize connection to the dronepublic static async Task ConnectToDrone(){                // Set up the UDP connection         string remotePort = "5556";         HostName droneIP = new HostName("192.168.1.1");                udpSocket = new DatagramSocket();         await udpSocket.BindServiceNameAsync(remotePort);         await udpSocket.ConnectAsync(droneIP, remotePort);         udpWriter = new DataWriter(udpSocket.OutputStream);             }

Send a commandpublic static async Task SendDroneCommand(string command){         udpWriter.WriteString(command);         await udpWriter.StoreAsync();}

AT*REF – takeoff/landing,resetAT*PCMD -airborn manipulation[sequence, flag,  roll, pitch, vertical speed, angular speed]

// Strafe drone forward or backward at velocity in range [-1,1]public static string GetDroneStrafeForwardBackward(uint sequenceNumber, double velocity){     // Convert the ratio into a value the drone understands     int value = FloatConversion(velocity);     return CreateATPCMDCommand(sequenceNumber, "0," + value + ",0,0"); }   // Return a full ATPCMD commandprivate static string CreateATPCMDCommand(uint sequenceNumber, string command){     return "AT*PCMD=" + sequenceNumber + ",1," + command + Environment.NewLine;}

3D printing

• 3D printing will go mainstream• Similar to printing 2D content• Print Preview• Print Ticket XML

Intro

3D Builder

1. Register for Print contractprotected virtual void RegisterForPrinting() {

// Create the PrintDocument. printDocument = new PrintDocument(); // Save the DocumentSource. printDocumentSource = printDocument.DocumentSource; // Add an event handler which creates preview pages. printDocument.Paginate += CreatePrintPreviewPages; // Add an event handler which provides a specified preview page. printDocument.GetPreviewPage += GetPrintPreviewPage; // Add an event handler which provides all final print pages. printDocument.AddPages += AddPrintPages; // Create a PrintManager and add a handler for printing initialization. PrintManager printMan = PrintManager.GetForCurrentView(); printMan.PrintTaskRequested += PrintTaskRequested; // Initialize print content for this scenario PreparePrintContent(); }
