  3. Industry trends

  4. Multi-screen entertainment 33% Companion apps enhance the TV viewing or gaming experience on the main television screen by providing interactive features, multiplayer & remote play, social integrations, editorial content, and additional information via a smartphone or tablet Multi-screened while gaming1 1 IEB Research and Business Intelligence Survey of ~1,500 US respondents, March 2012

  5. Second screen experiences Gaming companions pair with either a specific game or console Social companions are primarily media and centered on sharing Network companions are specific to a show and offer deep content extras Event companions pair with an event and offer behind-the-scenes & streaming Controller companions pair with a service provider and offer full media control

  18. HTML5/JavaScript applications that extend the functionality/interactivity of console titles Apps run in an embedded browser within the Xbox SmartGlass application Advantages of the Hosted SmartGlassexperience model Discoverability Consumers do not need to “find” and download applications one-at-a-time Applications automatically appear when the corresponding console title is being played Web development model Use of HTML5/JavaScript allows for cross-platform applications without having to write a separate, native app for each platform End-users get access to applications regardless of their device SmartGlass experiences

  21. Initialize Xbox SmartGlass and process messages // Initialize Xbox SmartGlass if( FAILED( XbcInitialize(XbcReceiveCallback, NULL) ) ) return; InitTime(); g_pPokerGame->ShuffleCards(); for(;;) // loop forever { // What time is it? UpdateTime(); // Check for messages XbcDoWork(); // Update the world UpdateTexCoords(); // Render the scene Render(); }

  22. Handle client connect event //-------------------------------------------------------------------------------------- // Name: XbcReceiveCallback // Desc: Callback function for Xbc events, such as client connect/disconnect and // title messaging. When we call XbcDoWork, if messages have come in, they will // use this callback for our app to receive them //-------------------------------------------------------------------------------------- VOID XbcReceiveCallback( HRESULT hr, PXBC_EVENT_PARAMS pParams, VOID* pvState ) { switch ( pParams->Type ) { case XBC_EVENT_CLIENT_CONNECTED: { // Add the player to the game and post the message to the screen PokerPlayer* pPlayer = newPokerPlayer( pParams->nClientId ); INT iPlayerIndex = -1; if ( SUCCEEDED( g_pPokerGame->AddPlayer(pPlayer, &iPlayerIndex))) { RtlZeroMemory( g_wstrMessage, sizeof( g_wstrMessage ) ); std::wstringstreamwss; // Convert the number from 0-based to 1-based for readability wss << "Player " << (iPlayerIndex + 1) << " connected!"; wcsncpy_s(g_wstrMessage, wss.str().c_str(), 20); } } break; . . .

  23. Process messages caseJson_FieldName: RtlZeroMemory(&buffer, sizeof(buffer)); XJSONGetTokenValue( hReader, buffer, ARRAYSIZE( buffer ) ); buffer[nTokenLength] = L'\0'; switch( tokenType ) { caseJson_String: if ( next == ACTION ) { next = NONE; if (wcsncmp( (constwchar_t *)buffer, L"fold", 4 ) == 0 ) { g_pPokerGame->PlayerFold( pParams->nClientId ); } elseif ( wcsncmp( (constwchar_t *)buffer, L"join", 4) == 0 ) { g_pPokerGame->PlayerJoin( pParams->nClientId ); } elseif ( wcsncmp( (constwchar_t *)buffer, L"start", 5 ) == 0 ) { g_pPokerGame->StartGame(); } elseif ( wcsncmp( (constwchar_t *)buffer, L"getstate", 8) == 0 ) { if ( g_pPokerGame->IsGameStarted() ) { g_pPokerGame->SendPlayerState( pParams->nClientId ); } } } break;

  24. Setup the SmartGlass experience Xbc.on("loaded", function (loadedData) { Xbc.Messaging.sendMessage({ action: Poker.Action.GETSTATE }); $("#join_button").click(function () { Xbc.Messaging.sendMessage({ action: Poker.Action.JOIN }); }); $("#start_button").click(function () { Xbc.Messaging.sendMessage({ action: Poker.Action.START }); }); $("#chip_count").text(money); $("#call_check_button").click(function () { if ($("#call_check_button").text() === "Check") { performCheck(); } else { performCall(); } }); $("#fold_button").click(function () { // Submit a fold performFold(); }); $("#bet_button").click(function () { performBet(); }); });

  25. Implement check via Table-Knock Xbc.on("accelerometer", function (value) { // We're assuming that an acceleration vector length greater than KNOCK_ACCEL_CUTOFF // Is a "table-knock" check // Calculate acceleration vector length varxVal = parseInt(value.x, 10); varyVal = parseInt(value.y, 10); varzVal = parseInt(value.z, 10); varvecLength = Math.sqrt(xVal * xVal + yVal * yVal + zVal * zVal); if (vecLength > KNOCK_ACCEL_CUTOFF) { performCheck(); } });
