User Experience

LESSON [2]

BY NISALA ALOKA BANDARA

Nature of User Experience

For a user, a good, or attractive

interface leads to a pleasant

interaction and nice user experience.

The term "User Experience" refers to

the Experience, the feeling the user

gets while she is interacting with the

system via its interface

**_Good Experience = Positive User Feedback

More Work Getting Done in Short Time_**

Experience is related to the individual: Every user would experience the same object differently. Different users will have different ‘feelings’ or opinions when asked to describe a single object or a system. One would highly appreciate a system while another individual complains that it is unbearable. This nature of experience is not to be confused as a defect of the system or the interface. A good experience designer needs to understand the very fact that experience is person related, not system related.

Experience is physiological and psychological: The way an individual perceives and appreciate an experience depends on individuals physiological and psychological condition. The individual’s mood influences her appreciation of the experience greatly while short-term or long-term individual related physiological conditions such as colour blindness or tiresomeness greatly affect an individual’s experience with an interface or a system

Experience is a moment of life It is important for any designer to understand that an experience can be best described, for an individual as ‘a moment of life’. Remember the first time you own a smartphone. The experience it generated with you will define how you would perceive and judge other experience and products, hereinafter.

Experience is a memory For a user, her experience with a system or an interface always leads to the creation of new memory. If you look back into your own memories, you would realize that many of your memories are actually experiences you had with different objects or individuals.

Experience create relationships Every experience connects you with something or someone. A positive experience will most likely to build loyalty which lasts longer than the one or the object which create it. This loyalty reinforces with every positive experience while help normalizing the effect of an occasional bad experience.

Experience sells your product. Probably the most important fact about the experience is, it actually drives sales volumes. The best example for the fact provides by the above-discussed scenario of Windows Mobile and iPhone. Think of a moment where you were proudly describing your smartphone with a friend and encourage her to buy one too. You, most likely, were describing your experience to generate attraction and loyalty. Your software or system is more likely to sell if the user’s experience with the system is exceptional.

Defining a Good user experience Elegant^ •^ It should look good, work well and produce good results. Addictive^ •^ It should call for the user to "keep doing it". Seamless^ •^ The interaction should be consistent throughout.

  • Work should be done in the best way without un-anticipated intermediate Fast activities.
  • The interaction should change the user in a positive way can create Memorable memories to recall.

Different Forms of Experiences PHYSICAL EXPERIENCE MENTAL EXPERIENCE EMOTIONAL EXPERIENCE SOCIAL EXPERIENCE VIRTUAL / SIMULATED EXPERIENCE OTHER FORMS OF EXPERIENCE

Mental Experience Mental experience is how would the user perceive the user interaction and understand it. Mental experience is highly dependent on the user’s mental state, emotions and previous experiences and vastly different from one udder to another. Two individuals experiencing the same event will always have two different mental experience off the event, always

Emotional Experience Emotional experience is a subgroup of mental experience which concerns about the emotions a particular experience generates within the user. Common emotions generated within users are love, anger, fear, excitement, shyness and empathy. The interaction can dictate how and when the user feels which emotion completing the experience. Roller-coasters are one good example for describing how experience can generate different emotions within the user. Roller-coaster does generate excitement, fear and sometimes anger within users at different stages of its motion.

Virtual / Simulated Experience One of the fastest evolving type of experience in the information society where the user is subject to a realistic experience which is not real. Based on the foundation of the experience, the simulated experience can either be virtual or augmented. Simulated experience is often relying on ‘fooling’ sensory organs of humans by means of stereoscopic sounds and visuals. The experience may be delivered as immersive or non-immersive experience. Popular mobile game Pokémon Go is the best example of non-immersive simulated experience while Microsoft HoloLens platform provides a fully immersive simulated experience to its user.

Other forms of Experience Apart from the main types of experiences described here, there can be other scenario sensitive experiences such as religious experience and spiritual experience which has very low involvement in computer science and software engineering.
