Abstract

The present invention proposes a technique for a user to locate activation area in a touch screen. The technique includes an insulating template or stencil, which is permanently or temporarily placed over or deposited and etched into the touch screen interface. The template limits the user ability to activate the touchscreen without accidental activation of unintended action area. The template is attached to or deposited on the touchscreen between the user and the touchscreen.

TOUCH SCREEN OVERLAY TEMPLATE OR STENCIL TO PREVENT ACCIDENTAL ACTIVATION

FIELD OF INVENTION

The invention generally relates to a touchscreen interface and more particularly to a template or stencil placed over the touchscreen interface.

BACKGROUND OF THE INVENTION

A touch screen interface is prone to accidental activation. In most cases, a user activates a function while trying to activate another function.

A conventional technique includes a pressure switch on the touch screen and allows the entire touch screen to be pushed in.

Another conventional technique includes synchronous activation button that requires two buttons to be pressed simultaneously to activate a function.

One other conventional technique includes a micro-fluidic membrane on top of the touch screen and created bumps with the micro-fluidic grid for the user to push in.

Yet another conventional technique includes a double tap feature, which requires a button to be pressed twice to activate a feature.

However, the conventional techniques do not limit interaction to certain areas, which result into accidental activation.

It would be desirable to have an efficient technique to limit the interaction to certain areas in the touchscreen interface.

BRIEF DESCRIPTION OF THE INVENTION

The present invention proposes a technique for a user to locate activation area in a touchscreen. The technique includes an insulating template or stencil, which is permanently or temporarily placed over or deposited and etched into the touchscreen interface.

DETAILED DESCRIPTION OF THE INVENTION

The present invention proposes a technique for a user to locate activation area in a touchscreen. The technique includes an insulating template or stencil, which is permanently or temporarily placed over or deposited and etched onto the touchscreen interface.  The template limits the user to activate the touchscreen without accidental activation of unintended action area. The template provides a layer that the user scans across with finger to locate an activation site without activating other sides. FIG. 1 depicts the insulating template or stencil.

Cutouts provide a tactile interface to allow the user to locate activation area without accidental activation. The touchscreen interface is flat and does not provide tactile information about the interface to the user finger.  Haptic markers cutout or on top of the template identify spe...
