Dexterity device with interchangeable components

Abstract

A handheld dexterity device comprising an internal member wherein the internal member has at least one protruding member having a finger toggle. A first portion and a second portion having at least one interconnecting channel wherein the first portion and the second portion are removably connected to each other encapsulating the internal member and forming an inner surface for the internal member to rotate smoothly around in wherein the finger toggle protrudes through the channel.

What is claimed is: 
     
         1 . A dexterity device for a user having a hand, the dexterity device comprising:
 an internal member wherein the internal member comprises at least one protrusion coupled to a finger toggle;   a casing comprising at least two detachably coupled portions, wherein the casing substantially encompasses the internal member and is shaped to allow the internal member to move freely in at least two dimension relative to the casing; and   a first channel pattern in one of the portions configured to allow the protrusion to pass through the casing and move within the first channel.   
     
     
         2 . The dexterity device according to  claim 1 , wherein the at least two detachably coupled portions comprise a first portion and a second portion, and wherein the first portion comprises an inner lip having at least one tab, the second portion comprises an outer lip having at least one slot and wherein the first portion and the second portion may be coupled by aligning the tab with the slot and wherein the slot is shaped to allow the tab to rotate within the slot locking the first portion to the second portion. 
     
     
         3 . The dexterity device according to  claim 1 , wherein a plurality of the portions comprise a channel pattern. 
     
     
         4 . The dexterity device according to  claim 3 , wherein the plurality of portions have different channel patterns and are interchangeable. 
     
     
         5 . The dexterity device according to  claim 1 , wherein the pattern is a maze, design, or figure. 
     
     
         6 . The dexterity device according to  claim 1 , wherein the portions each have an outer surface that is textured or smooth. 
     
     
         7 . The dexterity device according to  claim 3 , wherein at least two of the channel patterns comprise a channel that connects the channel patterns from one portion to another portion when the portions are coupled together. 
     
     
         8 . The dexterity device according to  claim 1 , wherein the portions are two hemispheres and wherein the internal member is substantially spherical. 
     
     
         9 . The dexterity device according to  claim 1 , wherein the casing is shaped to fit comfortably within the hand of the user. 
     
     
         10 . The dexterity device according to  claim 9 , wherein the hand has a palm, and wherein the casing is substantially spherical and sized to fit in the palm of the user. 
     
     
         11 . A method for providing a dexterity device to a user having a hand, the method comprising:
 providing an internal member comprising at least one protrusion that is coupled to a finger toggle;   forming a channel pattern in at least two detachably coupled portions;   situating the toggle in the channel; and   attaching the portions to form a casing that encompasses the internal member and allows the internal member to move freely in at least two dimension relative to the casing.   
     
     
         12 . The method of  claim 11  further comprising allowing the user to rotate the internal member by the finger toggle within the channel 
     
     
         13 . The method of  claim 11 , wherein the at least two detachably coupled portions comprise a first portion and a second portion, and wherein the first portion comprises an inner lip having at least one tab, the second portion comprises an outer lip having at least one slot, the method further comprising coupling the first portion to the second potion by aligning the tab with the slot and rotating the tab within the slot to lock the first portion to the second portion. 
     
     
         14 . The method of  claim 11  further comprising forming the channel pattern of one portion to be continuous with the channel pattern of another portion when the portions are coupled together. 
     
     
         15 . A modular dexterity device for a user having a hand, the dexterity device comprising:
 an internal member wherein the internal member comprises at least one protrusion coupled to a finger toggle;   a casing comprising at least two detachably coupled portion s including at least a first portion and a second portion, wherein the casing substantially encompasses the internal member and is shaped to allow the internal member to move freely in at least two dimension relative to the casing;   a first channel pattern in the first portion to allow the protrusion to pass through the casing and move within the first channel pattern; and   a fidget tool in the second portion, wherein different second portion s may be interchanged to allow the user to use multiple fidget tools with the same device.   
     
     
         16 . The modular dexterity device of  claim 15  wherein the fidget tool is a second channel pattern. 
     
     
         17 . The modular dexterity device of  claim 16  wherein the first channel pattern is continuous with the second channel pattern when the portions are attached. 
     
     
         18 . The modular dexterity device of  claim 1 , wherein the fidget tool is selected from the list comprising spinners, buttons, ball bearings, clickers, and a joystick. 
     
     
         19 . The modular dexterity device of  claim 15  wherein the first channel pattern includes a dampener to control the rate of rotation of the internal member within the casing. 
     
     
         20 . The modular dexterity device of  claim 19  wherein the first portion is interchangeable with alternate first portion wherein the resistance of the dampener varies between the alternate first portions.
