iPhoneの加速度センサーをPCから見たい！-2
やっとMacなしで加速度センサーの値をPCから見ることに成功。
と言うわけでiPhoneの加速度センサーの状態をPCで見れると色々楽しいんだと思うんですよ
の続き。
The Big5 application for Apple iPhone and iPod touch is a simplified gateway to your web apps.
↑を使って、PCのアプリに加速度センサの値を送信するサンプル。
使い方
概要/ソースコード
- Big5アプリからJavaScriptでローカルのHTTPサーバにXMLHttpRequestする。
- cgiMotionSensor.py

- motiontest.html
- Big5アプリで開くhtmlファイル。
- cgiMotionSensor.pyがたとえば192.168.0.6で起動していれば、192.168.0.6:8000/motiontest.htmlをBig5で開く。

- motiontest.js
- Big5アプリで取得できるようになったiPhoneの加速度センサーの値をHTTPサーバにXMLHttpRequestするJavaScript。

加速度センサーの返す値。
- x:平面におき、左側に傾けたときに-1。右側に傾けたときに1。
- y:垂直に置いて上側を天に向けたときに-1。下側を天に向けたときに1。
- z:画面を上にして平面に置いたとき、-1。裏にしたときに1。
動作環境
Ubuntu10.04とiPhone3Gでしか確認していません。
他の環境とかだとどうなのかなー。
*1:触らないことw
