Respected Sir, <br><br>I am a GSoC enthusiast and I would like to work on the development of a Multi-touch based User Interface for Blender.<br><br>Multi-touch denotes a set of interaction techniques which allow
computer users to control graphical applications with several fingers.
The multi-touch technology is in a development stage and offers immense
opportunities - both technical and economical. It will help in putting
computers to a variety of new applications and open up new kinds of avenues. The technology heralds a new ear in the way we interact with computers. It provides the users a more natural way of interaction with computers. <br>
<p></p>
<br>I feel that Multi-touch has started to show that it will be the next-big-thing in the field of User Interface.<br><br>It is much more intuitive and friendly way for an architect or a
designer to develop and show models with his both hands by directly
touching the models instead of using the mouse as a pointer device
which is more abstract.<br><br>With the coming of <a href="http://www.blender.org/news/article/blender-25-progress/">Blender 2.5</a> and the <a href="http://blenderartists.org/forum/showthread.php?t=97197">discussions</a> at the forum, I feel a multi-touch based user-interface for blender is imminent. <br>
<br>As the UI model for Blender 2.5 is based on MVC ( "Model, View, Controller" ) which proposes to strictly separate code for "Model" (the data) from
"View" (the interface, visualizations) and from "Controller" (the
operations on data). ( <a href="http://en.wikipedia.org/wiki/Model-view-controller">MVC -Wikipedia</a> ) , this will greatly help in the implementation of methods for using multi-touch devices with Blender.<br><br>The <span class="searchword1">multi</span>-<span class="searchword2">touch</span> device can be exposed as a <span class="searchword0">blender</span> sensor and several Blender objects can have a muti-touch sensor and thus can receive the same events.
The touch events can be sent to a gesture recognition module so that complex gestures can also be used for effectively using the multi-touch user-interface besides preliminary gestures like navigation by single touch, zooming , roatation etc.The <span class="searchword0">Blender</span> sensors will be connected to a controller which when triggered by an event will then by using the generic data and tools api will do the required operation.<br>
<br>Using an ANN based gesture recognition module will let the user customize and train their interactive-surface to do the fucntions as required on a particular gesture.<br><br>References :<br>The following projects can be very helpful in completing the project and saving time - <br>

<br><br>I am very much hopeful that intelligent multi-touch surfaces will
start replacing desktops and laptops that we see as shown very
much in hollywood movies and to some extent in high profiles labs and
military installations. [ commandline will however exist too :) ] I
have been working with MT stuff for over one-and-half years and have
developed one of my own FTIR based setup ( <a href="http://www.youtube.com/watch?v=wp8SpXfChkY" target="_blank">http://www.youtube.com/watch?v=wp8SpXfChkY</a> ) and currently developing a laser based planar MT surface. On the software side I have also build a simulator ( <a href="http://code.google.com/p/qmtsim/" target="_blank">QMTSIM</a> ) for fast and efficient development of Multi-Touch software even if you dont own a MT surface. <br>
<br><br>I am looking forward for a positive reply from your side and I feel
that you will make me conversant about my prospects for this project
under your guidance. I am hoping to make a full proposal with a time
line and the deliverables and start working if you think that this
could be a viable GSoC project.<br>
<br>Waiting for your comments and suggestions eagerly !!<br clear="all"><br>-- <br>Cheers,<br><br>Ashish Kumar Rai<br>Electronics Engineering Department,<br>IT-BHU<br>
