1. Low-fi testing is conducted very early on the product development – usually on paper prototypes. Where as hi-fi testing is conducted late on the product development usually on a complete product.
  2. Quick feedback – low-fi testing provides a quick feedback as the complete features are not built, where as hi-fi testing provides a late feedback
  3. In low-fi testing, moderator must be very familiar with prototypes and should ensure that the user is comfortable and understands the task in hand. In hi-fi testing moderator will have limited responsibilities
  4. Not all aspects are tested in low-fi testing. Aspects of graphic or visual design do not come in to play in low-fi testing.
  5. Interactivity will be less in low-fi testing, where as it will be more in hi-fi testing.
  6. People tend to comment on low fidelity prototypes, where as people will be bit hesitant to comment on things that look final
  7. Can easily create and test a series of low fidelity mockups, not so in hi-fi testing.
