Abstract

A fluid user interface is presented for applications such as immersive multimedia. In one embodiment, one or more sprays or jets create an immersive multimedia environment in which a participant can interact within the immersive multimedia environment by blocking, partially blocking, diverting, or otherwise engaging with a fluid, to create computational input. When the fluid is air, a keyboard can be implemented on cusions of air coming out of various nozzles or jets. When the fluid is water, the invention may be used in environments such as showers, baths, hot tubs, waterplay areas, gardens, and the like to create a fun, playful, or wet user-interface. In some embodiments, the spraying is computationally controlled, so that the spray creates a tactile user-interface for the control of such devices as new musical instruments. These may be installed in public fountains to result in a fluid user interface to music by playing in the fountains. The invention may also be used in a setting like a karaoke bar, in which participants perform music by playing in a fountain while they sing. Small self contained embodiments of the invention may exist as pool toys, bath toys, or decorative fountains that can sit on desk tops, or the like.

Claims

1. A user interface, said user interface including:

a housing, said housing having a plurality of openings;

means for supplying pressurized fluid through said openings;

a plurality of restrictometers, each of said restrictometers supplying an electrical signal that is responsive to an extent to which fluid flow is restricted through a corresponding opening by a user of said user interface;

an output means responsive to input from said plurality of restrictometers.

19. A musical pipe organ flute comprising said user interface of claim 1 wherein said output means is for producing a unique sound in response to the restriction of each of said openings.

20. The musical fluid pipe organ flute of claim 19, further including a mouth input and an embouchure controller, said embouchure controller for affecting said fluid supply in response to said mouth input.

2. A user interface, said user interface including:

a fluid supply;

a plurality of fluid jets;

a plurality of sensors to each sense interaction between a user of said user interface and fluid passing through said fluid jets;

an output means responsive to input from said plurality of sensors.

3. The user interface of claim 2 in which said output means includes a processor, said processor including a decision process, said decision process selecting from a plurality of symbols each in response to obstruction of one of said fluid jets.

4. An input device, said input device including:

one or more water jets defining a plurality of symbol areas;

at least one user sensor for sensing interaction between a user and water passing through said one or more water jets, said sensor for sensing which of said symbol areas a user interacts with;

a processor responsive to an input from said sensor, said processor for determining which of said symbol areas said user is interacting with and generating an output in response to said determining which of said symbol areas said user is interacting with.

5. The device of claim 4 in which said interaction is touch.

6. The device of claim 5 in which said one or more water jets is an upward directed water jet, and said symbol areas are regions of height.

7. The device of claim 6, further including a jet height controller, said jet height controller responsive to an input from said processor, an input signal to said jet height controller being derived in response to which of said symbol areas are selected.

8. The device of claim 7, including means for measuring location of said touch, said height being set equal to a height determined to be nearest said location, said height maintained at that level by way of a closed-loop controller.

9. The device of claim 6, further including a tactile jet controller, said controller responsive to an input from said processor, an input signal to said controller being derived in response to movement between said symbol areas, said tactile jet controller rapidly altering a user feelable aspect of said jet in response to the movement between said symbol areas.

10. A musical instrument based on the device of claim 6 where each of said symbol areas corresponds to a musical note, and said output is the sounding of a tone corresponding with said musical note.

11. The device of claim 5 wherein said one or more water jets comprises a plurality of water jets and further comprising a manifold for supplying said plurality of water jets, and wherein each jet defines one of said symbol areas.

12. A musical instrument based on the device of claim 11 where each of said symbol areas corresponds to a musical note, and said output is the sounding of a tone corresponding with said musical note.

13. A water keyboard based on the device of claim 11 where each of said symbol areas corresponds to a keyboard entry, and said output is the generation of a symbol corresponding with said keyboard entry.

14. The device of claim 13 in which said symbol is a discrete symbol with at least one additional attribute.

15. The device of claim 14 in which said attribute is the time at which said symbol is selected by said user.

16. The device of claim 14 in which said attribute is an attack time and a release time.

17. The device of claim 14 in which said attribute is an amplitude attribute, and in which said amplitude attribute is proportional to how far down said jet was pressed.

18. The device of claim 14 in which said attribute is an amplitude attribute, and in which said amplitude is proportional to the degree to which said jet was blocked.

21. A user interface for use with a pressurized fluid, said user interface including:

at least one sensor to sense a plurality of modes of contact between a user of said user interface and said fluid;

a processor for processing output of said sensor, said processor including a decision process, said decision process selecting from a plurality of symbols each in response to one of said modes of contact.

a housing having at least one opening;

a water supply system for delivering pressurized water through said at least one opening;

at least one detector for detecting a change in water delivered through said at least one opening; and

an effect controller responsively coupled with said at least one detector wherein when said at least one detector detects said change in water, said effect controller produces at least one effect.

23. The water flow control system of claim 22 wherein said at least one detector is a restrictometer, said restrictometer configured to generate a signal when said restrictometer detects a fluctuation in volumetric flow of water.

24. The water flow control system of claim 22 wherein said at least one effect produced by said effect controller is an auditory effect.
