Build Your Own Multitouch Surface Computer

Build Your Own Multitouch Surface Computer
Software So now we’ve completed the hardware section. The process of building a multi-touch computer is far from over, though, we need to get the software installed and configured so that we can actually use the thing. The central software that powered our rig is Touchlib , an open source library which takes the visual data received by the camera and parses it into touch events, which can be used by other programs to provide multi-touch control. Some programs implement this library directly, allowing for standalone multi-touch apps, while others, such as those written in ActionScript, require an extra software layer to allow the program to receive touch input. In this section, we’ll explain how we got both up and running. But, there’s something else we had to take care of first. Fortunately, PC users are famously unconcerned with what things are “meant to” do, and enterprising multi-toucher Alex Popovich has written a driver that allows the PS3 eye to be used with a computer. 1. 2.

Make your own multitouch projected table Multitouch, it's all you bloody hear about these days. If another person stops me in the street or blocks my car in just to shout "Apple have invented a multitouch cellphone!" into my face, I'll scream. Okay, so a huge company spent over two years developing a compact screen that could respond to more than one finger jabbing at it. So what? What's far more impressive to my mind is this four-day project to make a multitouch table: It all relies on the wonderfully-named Frustrated Total Internal Reflection (FTIR), whereby the path of LED light internally reflected between a sheet of acrylic and a diffuser is changed by the touch of a finger or other object placed against the top acrylic. I'm really tempted to make one of these myself, it looks like great fun. Multitouch Table Experiment [via MAKE]

StereoMood Interactive Multitouch Display This multitouch display screen design is based on the description in Jeff Han's paper, Han, J. Y. 2005. Low-Cost Multi-Touch Sensing through Frustrated Total Internal Reflection. In Proceedings of the 18th Annual ACM Symposium on User Interface Software and Technology The figure below comes from his web site. An acrylic panel is edge lit with infrared leds. Since most hobbyists can't afford multiple projectors (i don't even own one, just borrowed it from dr.eel), my design uses a ceiling mount that swivels so that the projector can be used either in standard mode (say for watching movies) or can be aimed downwards, bouncing off a reflector and onto the multitouch display screen. The screen itself can be constructed from hardware store materials and hand tools. touchlib

Multi-touch Table | CSP Research & Development Multi-touch displays are the natural evolution of the old touch screens as they are capable of recognising multiple touches at the same time. This way of dealing with the hardware (and applications) opens up a host of new opportunities for human-computer interaction, enabling the objects on a screen to be directly manipulated by the user. For this reason these techniques are also known as natural user interfaces. There are different ways to create multitouch screens, depending on the context of use and the size required for the display. The techniques that allow the realization of multi-touch hardware, are based on different solutions such as capacitive, resistive, motion, orientation, pressure and so on. The one we chose to implement our table is a computer vision based technique and is called Laser Light Plane (LLP). How LLP works. Each vision based techniques consist of a camera, an infrared light source and a display. Laser Light Plane CSP Mutlti-touch table. CSP Multi-Touch Table
