To add to what Ashley is saying, there's a solution, while still using Javascript for the plugins.

The core framework can be C/C++ (and let's be honest, C/C++ can be compiled and run everywhere). The core framework can also embed the V8 JS engine. V8 is the fastest of the three vendors' engines. It's not even using full JIT, its compiling to native on the first pass (if I remember the numbers right, it's something like 1 mb of code in 200 ms).

Since all successfull game framework is using a scripting language, let it be JS !

And for the "restrictions" on iOS, there's no problem with that. The author of ImpactJS is already doing that. If you are building JavascriptCore from the Webkit sources (meaning V8 + various bindings), you can embed it in your iOS app, and go to the AppStore.

In fact, Apple doesn't want to have an other engine. You can grab the sources of Webkit, of JavascriptCore, and do your own build (but only those, so no Gecko/FF on iOS, and no Rhino/Squirell extreme...)

Just for the information, the Tobbii is recording the glint of an IR light on the retina. So no arousal information from pupil dilatation.

Another information : you can't infer what people are doing just by looking at their mouse trail patterns (because in the end, it's just that). You need to correlate that with what's onscreen at the moment they were looking.

And no computer, available at the right price for the public, can record a fullscreen video (let say something starting from 1440x900) while generating the graphics at the same time, without stuttering (think about fullframe acquisition, storing in RAM, realtime compression and disk access time, while generating graphics...)

And, just for the record, I worked with those, so I don't say they are not useful : for disabled people, hemiplegia/tetraplegia, it's a wonderful tool. It's the difference between locked in your body, and interacting at least with a computer to say and do things to the world...

You don't need a particular plugin, since the eye tracker moves your mouse cursor.

imothep85 : I don't really understand your question. Can you reformulate it ?

ptbcomposer : on the AppStore, at least, there's more booksale than app sales. And among apps, what's selling the most is "books" apps. In fact those are apps with only text, or text with a few effects.

So the market is good for that kind of stuff.

I'm working on that kind of things, so if you want to ask some questions, go for it ! <img src="smileys/smiley1.gif" border="0" align="middle" />

In the end, what's the most important, if you want to make sales (it's not the same if you only want an artistic outcome, the work isn't the same) : marketing. Marketing, marketing, marketing, marketing !

With that, you can have great sales figures with an "average" game, but without coverage (marketing), an awesome game won't do any sale...

simpleex: although the PubNub system is interesting (and close to what I'm searching to integrate), but do you find their pricing plan attractive ?

simpleex : the plugin guru is rexrainbow !

Anyway, you can come to the IRC chan, there's already other french coders there <img src="smileys/smiley1.gif" border="0" align="middle" />

For the moment, you can add a Sprite, which consists of a bitmap grid. Don't forget to delete it before export ;).

0plus1: at least for device access, it's in the HTML5 spec. For some browser, you can already use getUserMedia() to access Webcam/microphone. With WebRTC, you can already do p2p in the browser.

With WebGL already available in UIWebView, and doing great, Apple is going to allow webapp to use them, with the release of the new iPad (because 2048x1536 is too huge to manipulate realtime with JS only). They are slowing allwoing pieces of the HTML5 spec in Safari, because everything that can be done with webapp lighten the financial burden of validating apps over the AppStore.

And since Apple is eating alive the tablet market, the other vendors (Windows Mobile/Bada/QNX/Android...) are forced to integrate those features, to remain competitive...

rexrainbow : yes, for sure ! The catmull-rom spline itself can't be copyrighted, since it's a mathematical algorithm, but that particular implementation and way of doing is coming from the original jQuery plugin creator, so I think you need to cite him as well (MIT license), but apart from that, go for it ! <img src="smileys/smiley2.gif" border="0" align="middle" />

0plus1: it depends. If you are targetting iOS, it's not possible because there's not JVM on non-jailbroken phones. If you know how to code a PhoneGap plugin for Android (here, you need to bind it to your .jar), it's possible. The overlay is going to be over C2's canvas, and you need to be sure that you cover the whole screen.

tonycrew : for the moment, you need to do that manually, by adding points for the "go-back" path, but thanks for the suggestion, I'm going to add it.
