SoundSpace Video
Video demonstration of our SoundSpace Interface.
Interface Technology
There are two main area if technology that we have been looking at that would make the SoundSpace interface possible.
Shadow Detection
Shadow detection is the most plausible and accessible technology for the SoundSpace interface. The SoundSpace interface would be projected onto the floor from the roof. A camera would also also mounted to the roof, this would be feed into a computer and using software to pick up the HSV colour space values. We would set the software to pick up the HSV values for shadow areas. People will be picked up when they enter the interface space as the projector is illuminating the area and when they are moving in the space they are breaking the light and casting a shadow. We then can convert this detection to isolate a persons co-ordinates with in the space, this will also be fed to the interface so the interface will react with a visual response and trigger the appropriate sound.
A more effective method of shadow detection, but more expensive and not as accessible would be to use infra red lights and cameras to detect people with in the space. Works similar to above but with more accurate results.
See sample videos below:
Tangible Multitouch Surface
Displax have developed a touch sensitive fil which is 98% transparent. This surface can be stuck to walls or the floor. This method would still use the projectors to project the interface onto the floor.
Another method would be to use the technology behind the Microsoft surface. This would be most expensive method and lest accessible but would provide the greatest result. This would be installed into the floor of a chosen space. This method would allow the touch sensitivity and display all in one. This also may allow the interface to be installed into brighter spaces where projectors are not as effective.
Final Outcome Filming
For the final outcome we have proposed to do a mock video to help us explain the interface. This video will then be projected onto the floor. Also an computer wil be used to allow people to switch between the video and a sample interface where they can controll one of the rings via a wacom tablet.
Below are some photos of our film day. I grabbed some green fabric to use as a green screen. Which worked quite well. We filmed one persona at a time, with them moving to the sound of the music. Alot of post production work needs to be done on this video before it is finished.
Paper Prototyping V1
Conducted our paper prototyping of the interface on the weekend. We used coloured card, black on one side and red on the orher. When someone pressed their foot onto a black piece it would be turned over so it was red to indicate the selection and placement on a beat within the sequence. Michael synced up audio so the users could hear the results. From this we found out that the interface works really well and is fun to use.
We also filmed the paper prototyping for further documentation.
SoundSpace Logo
I have been working on the logo/branding for our group. The logo is a visual section of the interface we are proposing.
SoundSpace
SoundSpace is the name for our group research project. We have been working on a multi-user tangible music interface. This interface will encourage people to work together to create music. The interface is based on a music sequencer and will use peoples feet and hand movements.
