41. FoxEye came to the world.

44. navigator.getUserMedia(
{video:true, audio:false},
function(localMediaStream) {
var videoTracks =
localMediaStream.getVideoTracks();
var track = videoTracks[0];
var myWorker = new Worker("textRec.js");
track.addWorkerMonitor(myWorker));
myWorker.onmessage = function (oEvent) {
console.log("Worker recognized: " +
oEvent.data);
};
var
elem=document.getElementById('VIDEO');
elem.mozSrcObject = dest.stream;
elem.play();
}, null);

45. var textDetector =
WebImage.createTextDetector(img.width,
img.height)
onvideoprocess = function (event) {
var img = event.inputFrame;
// テキスト認識処理を実行
var words= textDetector.findText(img);
var recognizedText;
for (var ix=0; ix<words.length; ix++) {
recognizedText
= recognizedText + words[ix] + " ";
}
postMessage(recognizedText);
};

46. Use cases(Amazon FireFly)
In our case, we can
use Yahoo Service,
like Yahoo Movie,
Yahoo Shopping,
Yahoo Search...

47. Use cases(Text selection in Image, browser)
