1. Windows 8.1 Äpipäev • Ondrej Stastny • Microsoft Premier Field Engineer

2. Agenda • Speech Synthesis • AR Parrot Drone UI • 3D printing

3. Speech Synthesis

4. Speech Synthesis Markup Language (SSML) • XML based language • W3 standard for speech synthesis

5. Mark • Notify app that certain point has been reached • Phoneme • Phonetic pronounciation • Say-as • Aid the synthesis processor • P, Break, …

6. // createthe data stream SpeechSynthesisStreamsynthesisStream; synthesisStream= awaitthis.synthesizer.SynthesizeSsmlToStreamAsync(text); // start this audio stream playing this.media.AutoPlay= true; this.media.SetSource(synthesisStream,synthesisStream.ContentType); this.media.Play();

7. AR Drone 2.0

8. Initialize connection to the drone publicstaticasyncTaskConnectToDrone() {       // Set up the UDP connection stringremotePort = "5556"; HostNamedroneIP = newHostName("192.168.1.1"); udpSocket = newDatagramSocket(); awaitudpSocket.BindServiceNameAsync(remotePort); awaitudpSocket.ConnectAsync(droneIP, remotePort); udpWriter = newDataWriter(udpSocket.OutputStream); }

9. Send a command publicstaticasyncTaskSendDroneCommand(stringcommand) { udpWriter.WriteString(command); awaitudpWriter.StoreAsync(); } AT*REF – takeoff/landing,reset AT*PCMD -airborn manipulation [sequence, flag,  roll, pitch, vertical speed, angular speed]

10. // Strafedrone forward orbackwardatvelocity in range [-1,1] publicstaticstringGetDroneStrafeForwardBackward(uintsequenceNumber, doublevelocity) { // Convertthe ratio into a valuethedroneunderstands intvalue = FloatConversion(velocity); returnCreateATPCMDCommand(sequenceNumber, "0,"+ value + ",0,0"); } // Return a full ATPCMD command privatestaticstringCreateATPCMDCommand(uintsequenceNumber, stringcommand) { return"AT*PCMD="+ sequenceNumber + ",1,"+ command + Environment.NewLine; }

11. 3D printing

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