• ergonomic parameters on values for: fingers, thumbrest, palm and volume curvature .
  paramters modify the skin using only sine and cosine functions to generate smooth curvature
  the problem: the border between a design and organic wobble is pretty small

• examples are: braille for blind people, engraved room information
  
  
  
  

• tactile structure to describe room usage: e.g. for laboraty, office, private within big anonymus buildings
  
  
  
  

• // 27-01-04 achieved so far
  
  / parameter based creation of the handle skeleton for one handletype
  / parameter based curvature modification by applying tigonemetric functions on skin vertexes, adjusting the geometry to chosen ergonomic desires
  / first example of skin structure / ornament / haptics / setup of the milling process of two-sided milling in wood
  
  

• // how to continue:
  
  / get the skeleton system to create a wide range of handletypes
  / better definition of the design / finetuning
  / incorporate more surface patterns: info_structure, braille, ornament
