Stephen P. Anderson through his 2010 seminar, “Seductive Interaction Design,” where he looks at ways we can employ psychology to design interactions that are more fun, engaging, and effective.
An example he gives of seductive interaction design in a set of stairs that have been painted to look like piano keys with sensors to play notes when stepped on. The design put use of the stairs up 66 percent in comparison of the stairs right next to them.
There are many paths to creating the type of innovative designs Anderson describes, but often, the need for familiarity and intuitiveness in interaction design takes precedence over unique or innovative interactions. Sometimes, however, unique combinations of platforms, requirements, constraints, user needs, and other factors demand new interactions or substantial redesigns of older ones.
The stairs example, is an interactive way to incentive users to do the action, in this case use the stairs instead of the elevator. This psicological factor plus the familiarity of the interactive elements, permits the user to operate these elements purely by previous experience and intuition, without any need of instructions.
In conclusion, I consider that the aplication of interactive design elements in our everyday society could improve in our way of living life, making it more entertaining and a good experience for the general public, and it can even be used to make a society more aware of different aspects like sustainability, transport, or even everyday actions like crossing roads.etc.
