The present invention relates to textile electronics. More particularly, the present invention relates to an interface having one or more pressure activated switches preferably integrated into a flexible fiber construction. The pressure activated interface is preferably operative via a mechanical interaction and functional in various electronic applications and/or operations.
The use of electronics in various manufactured materials is well known; see for example, U.S. Patent Nos. 6,360,615 Bl, 6,210,771 Bl, and 5,371,326; U.S. Patent Application Publication No. 2002/0135457 Al; PCT International Patent Publication Nos. WO 02/055923 Al and WO 02/32665 Al ; and/or UK Patent Application No. GB 2 373 863. Devices such as conductive traces, bio-sensors, electrodes, computers, electronic circuits and the like have all been incorporated into textiles. As the benefits associated with the various types and/or configurations of textile electronics become more apparent, the desirability and need for simple, effective and efficient, as well as intuitive user interface solutions becomes more apparent. Hence, there is a need for an input device or interface that is complementary to the various electronic functions/systems provided by the different textile electronics and/or the materials accommodating such electronics.
It is an object of the present invention to provide an interface suitable to address the above-identified need for simple, effective and efficient, as well as intuitive user interface solutions.
It is another object of the present invention to provide such an interface that has a flexible textile construction.
It is another object of the present invention to provide such an interface having one or more switches and corresponding interface graphics.
It is another object of the present invention to provide such an interface having one or more switches easily manufactured using conventional textile fabrication methods.
It is another object of the present invention to provide such an interface that is cooperative with a garment and/or one or more textile electronic devices or equipment.
It is another object of the present invention to provide such an interface operatively connectable or cooperative with a variety of electronic devices/systems.
It is still another object of the present invention to provide such an interface for accomplishing a variety of different electronic operations or functions. These and other objects and advantages of the present invention are achieved by an interface having a textile construction with one or more collapsible spaces or cavities therein. The one or more collapsible cavities are preferably fashioned so as to be raised or elevated from the surface of the textile interface. Preferably, one or more strips or leads have one or more conductive contact areas associated therewith and cooperative with the textile interface such that at least two of the one or more conductive contact areas can electrically communicate via a mechanical interaction.

The intuitive interface is preferably in parallel with the properties or characteristics of the textile construction. Also, one or more switches of the textile interface can be made to be impermeable should waterproofing and/or insulating be required for a particular interface solution.

Also, the textile interface 1 can have one or more securing mechanisms 55, such as that shown if Fig. 7, for selectively holding said one or more collapsible cavities 10 closed.
It is further noted that the one or more collapsible cavities 10 and/or the fluid space 33 may be at least partially filled with a gas, liquid andor semi-liquid material or substance suitable for providing support and/or any other desired characteristic to the one or more collapsible cavities 10 and for allowing the one or more collapsible cavities 10 to collapse or close the fluid space 33 such that the one or more conductive contact areas 30 are brought into electrical communication.
