  • Stylus tool with deformable tip
    Patent number: 9671877
    Abstract: A passive stylus with a deformable tip is described herein. In one embodiment, a thin annular body configured to be hand-held with a chisel shaped tip disposed at the first end of the body is provided. The chisel shaped tip includes a deformable material such that the chisel shaped tip is operable to interface with a touch a sensitive surface with a detectable surface area when a first pressure is exerted on the body and translated to the chisel shaped tip. The chisel shaped tip is operable to interface with the touch sensitive surface with a second detectable surface area, this one different from the first detectable surface area, when a second pressure is exerted on the body and translated to the chisel shaped tip. The stylus may include a second tip on the back end for providing an erase function.
