Engineering enjoyment as per Karasek model

Karasek proposes a Demands-Control-Support model for work. According to Peeter, Asbjorn and Jan -- in a paper title "Enjoyment: Lessons from Karasek" -- the model can be applied to engineering of enjoyment as well

A design for enjoyment may utilize

• variability, unpredictability, surprise,
• engagement (with high frequency, immediate response),
• co-active, socially enabling

Authors state:

• user should feel in control and also needs to see the effects of the user actions
• user should be given multiple options / variations; give more than they expect; allow them to personalize
• design should make the user feel that she is part of a group; should allow her to do things together with others.
