Abstract

A fountain which allows interaction by the viewer which alters the fountain'"'"'s water display. An apparatus and method are disclosed wherein a person viewing the fountain may provide a control indication which causes the fountain display to vary. The preferred embodiment uses an ultrasonic sensor to determine the height of a viewer'"'"'s hand above a sensor and the water pressure delivered to the fountain is adjusted according to position of the viewer'"'"'s hand. The invention may use a single or a plurality of sensors to control different groups of jets thereby allowing a large variety of fountain design options.

Claims

1. A method of controlling a water fountain display, comprising the steps of:

monitoring an indication made by one or more users of said fountain display;

in response to said step of monitoring, adjusting the pressure of water delivered to one or more nozzles of said fountain;

wherein said step of monitoring comprises monitoring a distance from at least one monitor of a hand of each of said one or more users, and wherein said hand of each of said one or more users is placed in registry with the at least one monitor.

2. A method according to claim 1, wherein each of said one or more users causes adjustment of a specific nozzle.

3. A method according to claim 1, wherein said one or more nozzles are arranged into a plurality of nozzle groups and wherein each nozzle group within said plurality of nozzle groups is controlled by a specific indication monitored from said step of monitoring an indication, wherein said specific indication is made by one of said one or more users.

4. An interactive display fountain, comprising:

means for monitoring an indication made by one or more users of said fountain display; and

means for adjusting the pressure of water delivered to one or more nozzles of said fountain, wherein said means for adjusting operates in response to an output provided by said means for monitoring;

wherein said means for monitoring comprises means for monitoring a distance from at least one monitor of a hand of each of said one or more users, and wherein said hand of each of said one or more users is placed in registry with the at least one monitor.

5. An interactive display fountain according to claim 4, wherein each of said one or more users causes adjustment of a specific nozzle.

6. An interactive display fountain according to claim 4, wherein said one or more nozzles are arranged into a plurality of nozzle groups and wherein each nozzle group within said plurality of nozzle groups is controlled by a specific output produced by said means for monitoring, wherein said specific output corresponds to a specific indication made by one of said one or more users.

7. An interactive display fountain, comprising:

a user interface for monitoring an indication by one or more users of said fountain display, wherein said user interface provides an output corresponding to said indication;

a variable speed pump for adjusting the pressure of water delivered to one or more nozzles of said fountain; and

a controller for controlling water pressure produced by said variable speed pump, wherein said controller operates in response to said output provided by said user interface;

wherein said indication is an object placed a distance away from said user interface.

8. An interactive display fountain according to claim 7, wherein said user interface utilizes ultrasonic distance measuring techniques.

9. An interactive display fountain according to claim 7, further including a variable output energy source for interactively adjusting the intensity of illumination sources associated with fountain.

10. An interactive display fountain according to claim 7, further including a variable output audio signal controller for interactively varying the sound intensity of a sound system associated with the fountain.
