Adjustable stylus pen

Abstract

An example stylus pen including a body includes a central axis, a first end, and a second end. In addition, the stylus pen includes an engagement tip disposed at the first end and including resilient cover. Further, the stylus pen includes an adjustment mechanism at least partially disposed within the body and arranged such that manipulation of the adjustment mechanism by a user causes the cover of the engagement tip to actuate between a first shape and a second shape. The cover of the engagement tip is arranged to engage with a touch sensitive surface to cause a change in a computing device when in either one of the first shape and the second shape.

What is claimed is: 
     
         1 . A stylus pen comprising:
 a body including a central axis, a first end, and a second end;   an engagement tip disposed at the first end and including resilient cover; and   an adjustment mechanism at least partially disposed within the body and arranged such that manipulation of the adjustment mechanism by a user causes the cover of the engagement tip to actuate between a first shape and a second shape;   wherein the cover of the engagement tip is arranged to engage with a touch sensitive surface to cause a change in a computing device when in either one of the first shape and the second shape.   
     
     
         2 . The stylus pen of  claim 1 , wherein the engagement tip also comprises:
 an elongate extension member that is axially movable relative to the body;   wherein the resilient cover is disposed over the extension member; and   wherein manipulation of the adjustment mechanism by a user causes the extension member move to axially relative to the body.   
     
     
         3 . The stylus pen of  claim 1 , wherein the adjustment mechanism includes a knob rotatably disposed at the second end of the body, wherein rotation of the knob causes the cover of the engagement tip to actuate between the first shape and the second shape. 
     
     
         4 . The stylus pen of  claim 1 ,
 wherein the first shape has a first engagement area when the tip is engaged with a touch sensitive surface;   wherein the second shape has a second engagement area when the tip is engaged with the touch sensitive surface; and   wherein the first engagement area is larger than the second engagement area.   
     
     
         5 . The stylus pen of  claim 1 , wherein the engagement tip has an axial length and wherein the axial length is increased when the cover of the engagement tip is actuated from the first shape to the second shape. 
     
     
         6 . A stylus pen for engagement with a touch sensitive surface, the stylus pen comprising:
 a body including a central axis, a first end, and a second end;   an engagement tip disposed at the first end and having an engagement area;   wherein the engagement tip is actuatable between a first position and a second position, wherein the engagement area is adjusted when the engagement tip is actuated between the first position and the second position; and   wherein the engagement tip is arranged to contact the touch sensitive surface with the engagement area to cause a change in a computing device when in either one of the first position and the second position.   
     
     
         7 . That stylus pen of  claim 6 , wherein the engagement area decreases when the engagement tip is transitioned from the first position to the second position. 
     
     
         8 . The stylus pen of  claim 6 , wherein the engagement tip comprises:
 an elongate extension member that is axially movable relative to the body; and   a resilient cover disposed over the extension member;   wherein transition of the engagement tip between the first position and the second position causes axial movement of the extension member relative to the body.   
     
     
         9 . The stylus pen of  claim 6 , further comprising an adjustment mechanism at least partially disposed within the body, wherein manipulation of the adjustment mechanism by a user causes the engagement tip to actuate between the first position and the section position. 
     
     
         10 . The stylus pen of  claim 9 , wherein the adjustment mechanism includes a knob, wherein rotation of the knob by a user causes the engagement tip to actuate between the first position and the second position. 
     
     
         11 . A computing system, comprising:
 a touch sensitive surface;   a display; and   a stylus pen, including:
 a body including a central axis, a first end, and a second end; 
 an engagement tip disposed at the first end; 
 wherein the engagement tip is actuatable between a first position and a second position, wherein the engagement tip is sharper in the second position than in the first position; 
 wherein the engagement tip is arranged to engage with the touch sensitive surface to cause a change on the display when in either one of the first position and the second position. 
   
     
     
         12 . The computing system of  claim 11 , wherein the engagement tip comprises:
 an elongate extension member that is axially movable relative to the body; and   a resilient cover disposed over the extension member;   wherein actuation of the engagement tip between the first position and the second position causes the extension member move to axially relative to the body.   
     
     
         13 . The computing system of  claim 11 , wherein the engagement tip is actuatable between the first position and the second position with an adjustment mechanism that is at least partially disposed within the body. 
     
     
         14 . The computing system of  claim 13 , wherein the adjustment mechanism includes a knob rotatably disposed at the second end of the body, wherein rotation of the knob causes the engagement tip to actuate between the first position and the second position. 
     
     
         15 . The computing system of  claim 11 , wherein the engagement tip has an axial length and wherein actuation of the engagement tip from the first position to the second position causes the axial length to increase.
