100″ Multitouch Table – EM Spectrum Exhibit

Posted by Jee Yeon Hwang

The 100″ multitouch table, multiuser exhibit table, is developed by Ideum with Adventure Science Center in Nashville, Tennessee. The exhibit is part of a large gallery space at the museum which focuses on astronomy.

The table consists of a surface, two computers, and projects. The contagious surface enables users to interact with the same program at the same time.

The 100″ surface (an 86″ viewable area) is one of the largest contiguous multitouch tables ever developed. The screen has a 16 x 5 ratio aspect and a 2304 x 800 pixel, high-resolution screen.

The exhibit table explores the electromagnetic spectrum. The extended aspect ratio mimics the spectrum itself, from radio waves to gamma rays. Users can then move images across the table and see how the images are displayed in each waveform.

The exhibit displays a variety of celestial and terrestrial images in a wide range of wavelengths. For example, NASA images of the sun can be seen in all wavelengths. Common and iconic objects were photographed in diverse wavelengths. For example, a birthday cake with candles, a toy robot, an alarm clock, and even a hand holding an iPhone are seen in visible, infrared, ultraviolet, and x-ray modes.


Microsoft Surface

Posted by Jee Yeon Hwang

Key attributes of Microsoft Surface
(1) Direct interaction
Users can manipulate digital information with their hands and interact with diverse contents by touch and gesture, without using a mouse or keyboard.

(2) Multi-touch contact
Surface recognizes various contact points simultaneously, not just from one finger, as with a typical touch screen, but many items at once.

(3) Multi-user experience
The horizontal form factor makes it easy for users to gather around surface computers together, providing a collaborative, face-to-face computing experience.

(4) Object recognition
Users can place physical objects on the surface to get different types of digital information and responses, including the transfer of digital content.

Tangible Table

This project came out from initial idea not technology which is covered now.
Each rectangualr sells make an relationship on tangible table and those interactions make sounds as well. very interesting project!!

The Reactable is a revolutionary new electronic musical instrument designed to create and perform the music of today and tomorrow. It combines state of the art technologies with a simple and intuitive design, which enables musicians to experiment with sound, change its structure, control its parameters and be creative in a direct and refreshing way, unlike anything you have ever known before.

The Reactable uses a so called tangible interface, where the musician controls the system by manipulating tangible objects. The instrument is based on a translucent and luminous round table, and by putting these pucks on the Reactable surface, by turning them and connecting them to each other, performers can combine different elements like synthesizers, effects, sample loops or control elements in order to create a unique and flexible composition.

As soon as any puck is placed on the surface, it is illuminated and starts to interact with the other neighboring pucks, according to their positions and proximity. These interactions are visible on the table surface which acts as a screen, giving instant feedback about what is currently going on in the Reactable turning music into something visible and tangible.

Additionally, performers can also change the behavior of the objects by touching and interacting with the table surface, and because the Reactable technology is “multi-touch”, there is not limit to the number of fingers that can be used simultaneously. As a matter of fact, the Reactable was specially designed so that it could also be used by several performers at the same time, thus opening up a whole new universe of pedagogical, entertaining and creative possibilities with its collaborative and multi-user capabilities.

Collaborative Computing

We talked about the Microsoft Surface last week. Here is a prototype idea that scales really well for multiple people quite smoothly.

Muscle-Computer Interfaces

A new type of way to interface with computers which I think makes a lot of sense in some situations. For example, the scenario played out in the video when both your hands are full with groceries and you want to open the trunk.
