Abstract

A stylus instrument for interfacing with a capacitive touchscreen of an electronic device. According to certain aspects, the stylus instrument includes a body portion and a tip portion with a ring connected thereto and supported at an angle relative to the body portion. The tip portion includes a pointer extending therefrom and aligned to point at the center of the ring. The ring includes a conductive contact surface configured to activate sensors of the capacitive touchscreen and accordingly facilitate functionalities of the electronic device. The configuration of the stylus instrument enables a user a precise visual guide in selecting and facilitating the functionalities of the device with a reduced amount of friction as a result of a void at or near the center of the ring.

Claims

1. A stylus instrument for interfacing with a capacitive touchscreen, the stylus instrument comprising:

a body portion connected to a ring component via a tip portion, wherein

the tip portion comprises a connector configured to support the ring component at a fixed angle relative to the body portion, and

the ring component comprises

     1) a void located at or near a center of the ring component and

     2) a conductive contact surface configured to activate sensors of the capacitive touchscreen; and

a pointer component protruding from the tip portion and aligned to point generally toward the center of the ring component, wherein an end point of the pointer component is recessed from a plane area defined by the conductive contact surface of the ring component.

2. The stylus instrument of claim 1, wherein the end point of the pointer component is recessed from the plane area by a distance between 0 and at least 6 millimeters.

3. The stylus instrument of claim 1, wherein the body portion is composed of a conductive material.

4. The stylus instrument of claim 1, wherein a diameter of the pointer component is less than a diameter of the void of the ring component.

5. The stylus instrument of claim 1, wherein the fixed angle is approximately 45 degrees.

6. The stylus instrument of claim 1, wherein a radius of the void is less than yet substantially the same as the width of the ring component, for minimizing material usage and yet still retaining sensitivity to the touchscreen sensors.

7. The stylus instrument of claim 1, wherein the fixed angle can be reset to an angle desired by the user by flexing the instrument to the desired angle.
