FINAL PROJECT - research into existing table-projects

Here are some links to table-projects(musical)
- Audiopad:
- Audiopad (PDF) composition and performance instrument for electronic music which tracks the positions of objects on a tabletop surface and converts their motion into music.
To determine the position of the RF tag on a two dimensional surface, they use a modified version of the sensing apparatus found in the Zowie Ellies Enchanted Garden playset To move the characters on-screen, children simply move them on the playset.

- Sensetable: A system that wirelessly tracks the positions of multiple objects on a flat display surface quickly and accurately.(similar to audiopad, but without sound.)

- Multi-Touch InteractionResearch(Jefferson Y. Han)(WEB)
- Low-Cost Multi-Touch Sensing through Frustrated Total Internal Reflection (PDF)
Camera based (need password)

- Lemur: unique and patented touchscreen technology that can track multiple fingers simultaneously.

- The maual input sesions (Golan Levin) (web)(pdf)
A series of audiovisual
vignettes which probe the expressive possibilities of free-form
hand gestures. Performed on a hybrid projection system which
combines a traditional analog overhead projector and a digital PC
video projector, the vision-based software instruments generate
dynamic sounds and graphics solely in response to the forms and
movements of the silhouette contours of the user’s hands.

- The Audiovisual Environment Suite (AVES) is a set of five interactive systems which allow people to create and perform abstract animation and synthetic sound in real time.

- Heavy rotation revisor: Input from five radio stations is analyzed, cut up into abstract fragments and thrown onto the desk. By using the mouse and headphones, the players can listen to the fragments, combine them and create abstract sound scapes.

- DiamondTouch (WEB)
- DiamondTouch (PDF): A Multi-User Touch Technology
A technique for creating touch sensitive surfaces is proposed which allows multiple,
simultaneous users to interact in an intuitive fashion. Touch location information is
determined independently for each user, allowing each touch on the common surface to
be associated with a particular user.
Antenna based

WORKSHOP Prosessing Atelier Nord

View this clip on Vimeo
Prosessing is a graphical tool in some javarelated language
I attended the prosessing workshop to be able to build a physical music-editor with extended soundfile representation.

Here are some comments to the qt-popup-meny chapters
(down right corner)
#1-#5 Basic shapes and drawing
#6 Calculating objects on another circle using cos and sin
#7-8 Controlling objects position, size, and movement with osc-communication from max/msp (in real-time))
#9-10 Experimenting with multiple shapes for soundfile representation, containing info about different prosessing paramenters(tentancles), voulme(size), sterio-panning(rotation)
#11-15 Creating multiple dots with arrays. Senario for soundfiles in time/amplitude-domain. By interaction of physical objects certain soundfiles will be highlighted for playback or edit
#16-17 Soundfile with an indicated length(line)
#18 Cursor experiments

TASK3 Touchable Services

View this clip on Vimeo
Using RFID tags in an urban envirement for retrieving url-links via a RFID-reader attached to a standard Mobile phone.
The RFID is a small/cheap tag that may contain a small amount of information, not requireing any power supply. They might contain an id-number, refering to a databasis, or an URL physical weblinks.

The information/webpages can eather be downloaded directly to the phone, or bookmarked to your mail, phone, or a friend.
We have examplified this service for community based underground shops(music, art) We imagine that the service may include scanning flyers, listening, or downloadiing recommendations, signing up for mailinglists etc.

Here are some comments to the qt-chapters popupmeny
#2 is an example from a RFID system already implemented in Japan. This is the identification maascot
#3-7 is suggesting a navigation-map in tram stations. By holding your phone over highlighted sectors of the city, the display will show info for venues included in the service, or download info
#8-13 Introducing "window-shopping possibilities. Listening to recomandations, or checking opening hours, signing up for email-services.
#14-16 Technical spesifications. When making contact between tag and phone you will have to make choices between download, mail-bookmark etc. At the same time you may watch basic info on coverart, and track/album-info
