Emotion-Centered-Design (ECD) New Approach for Designing Interactions that Matter.

The emotional dimension of users of information and communications technologies (ICT) is a key aspect in user experience (UX), as designers’ main objective is to ensure users are happy (satisfied, engaged) with their interaction designs. However, current UX design methods focus on ensuring that efficacy (success achieving a specific task) and efficiency (in the fastest, best way possible) are successfully achieved. The satisfaction of the user is evaluated at the end of the process, and evaluated in reference to the efficacy and efficiency of their experience. In this paper, the author presents a new approach (Emotion-Centered-Design, or ECD) in which the key to successful interaction design (happy users) is brought about by placing emotions at the center of the design process, versus doing so at the end. By doing so, designers can deliver more significant experiences, increase user experience satisfaction, and identify new ways to innovate in interaction design, as well as add more value to users.
