Abstract

The passive pen comprises a conductive tip coupled to a compressible mechanism. As force is applied to the pen tip, the compressible mechanism causes the tip to retract into the pen and a conductive mass to move closer to an input surface. The change in distance between the conductive mas and input surface increases the capacitive coupling between the pen and input surface thus providing an indication of the amount of force applied to the pen tip.

3. Short Summary

The passive pen comprises a conductive tip coupled to a compressible mechanism. As force is applied to the pen tip, the compressible mechanism causes the tip to retract into the pen and a conductive mass to move closer to an input surface. The change in distance between the conductive mas and input surface increases the capacitive coupling between the pen and input surface thus providing an indication of the amount of force applied to the pen tip.

Force Enabled Passive Pen

Figure 1 illustrates a passive pen in (1) a non-compressed state and (2) a compressed state. The conductive pen tip is connected to a compressible mechanism which allows the pen tip to retract into the body of the pen when force is applied to the pen tip. The compressible mechanism may comprise, for example, a spring or compressible material (e.g., an elastomer).

Furthermore, the conductive pen tip surrounded by a conductive region which capacitively couples wit...
