3.3 Physical modelling

• Physical models are useful in understanding how an object will be physically manipulated or used by a user.


  They can provide important information about:

  • Ergonomics and fit
  • Relationships between the internal structure and external structure
  • Aesthetic considerations
• Ergonomics and fit


  The model can show how the design will fit to the user's body or  held in the user's hand.
• Relationships between the internal structure and external structure


  For example, how the electronic components of device might influence the external structure of a design, and vice versa. This could include the placement of ports, switches, buttons, grips, etc.
• Aesthetic considerations


  Form, scale, shape, texture, and color can all be explored through creating a physical model. 
• Scale models

  A model that is either a smaller or larger physical copy of an object.

  Scale models are often used in architecture where smaller models of a building are presented or some testing situations when it is financially or practically impossible to test a full-scale model.

  Scale models are advantageous for communicating the form, thinking, aesthetics or ideas behind a design. 
• Aesthetic Models

  Model developed to look and feel like the real product, evaluate user appeal of the aesthetic elements of the design or in ergonomic testing.

  It can be used to evaluate the properties of a material:

  • Weight and balance: using materials similar in weight and density to the final production material, the model could be used to evaluate how heavy a design is, or how it balances. ex. sports equipment
  • Texture and surface qualities: finishes, paint, or textures might be applied to the surface to communicate how the the surface looks, feels, or reflects light.
