“Defining the criteria for effective interaction design” – Lauralee Albern
ExperienceExperience is a key aspect in all interactive designpieces as it is majorly highlighted in designphilosophy. In philosophy experience underlieswithin our sub consciousness, it collectively createsour likes and dislikes outlining our aesthetics.Although our own personal experiences will dictatehow we react to an interactive piece, in order for itto be effective it needs to provide an interestingand positive environment accessible for themajority of personalities.
How does effective interaction design provide peoplewith a successful and satisfying experience?• Effective interactive pieces should be visually obvious, yet maintain a suspense that invigorates the user• They should be engaged but also grasp the concept of the works with ease• Users should not be concerned or involved with the inner workings of the piece• Minimal effort should be required in order for the piece to be fully functional
- Understanding of UsersFor an interactive installation to be allegeable the users musthave a developed understanding without supervision orinformation being provided.- Effective Design ProcessIf the design process during research is developed systematicallythen the outcome will be potentially free flowing andclear, allowing the user to become immersed in the interactivity.- ManageableThe piece must be managed simply and should not requireconstant supervision for full functionality, this allows the user toconnect with the piece on a more personal level .
- Aesthetic ExperienceIn order for the user to be immersed in the experience itmust hold aesthetic qualities. Aesthetics create a moredurable experience and allows users to connect with thepiece on a sub conscious level. Aesthetics in an interactivepiece allow us to act naturally and submerge ourselveswithin the concept, this therefore should not require anythought or judgment from the user create his or herexperience.
- AppropriateAn interactive piece should be engaging for all audiences, itshould not disengage any cultures etc. It should stand by ethicalrequirements and consider social, cultural, economical andtechnical aspects.- Learnable / UseableThe piece should be simple to use, and be useable for anyindividual, users should not have to be instructed on how theinteractive piece involves them, they should instantly adapt andinvolve them.
- NeededThe topic presented should be of importance and relevant, itmust be conceptual and provide a purpose as to why it should beinteracted with.- MutableIt should be catered for and engage all types of audience, itshould not single out, or have a required target audience.
Experiences and InteractionHow we define an experience is entirely dependent onour personal perception and emotional connection towhat we are interacting with. Experience is a key factor ininteraction, and it should be considered in two ways;- The existent emotional experience- The created emotional experienceEvery user will create their own experience from aninteractive piece, even though they are provided with thesame basic information and tools.
It is hard to clearly state what in fact causes an emotional reaction, butan obviously statement to make is that it is directly linked to anexperience or connection we have with the related emotion.Psychologist Brian Parkinson states that emotional experience isseparated into four factors;- An external stimulus or situation, which is considered the key factor.- How the body reacts to a given situation, for example, arousal or fear.- Our facial expression in the situation.- Our reaction and action tendencies, for example, advancing in a threatening way shows anger, or retreating suggests fear.
Personal experience will define how we react incertain situations, whether it is a good or badexperience.An experience can be defined as a knowledgethat is gained through involvement with anevent, be it physical or conceptual.Emotions are triggered by our prior knowledge,this can branch out and effect situations weencounter.
“Emotions and feelings are not a luxury, they area means of communicating our state of mind toothers. But they are also a way of guiding ourown judgments and decisions. Emotions beingthe body into the loop of reason”(Damasio – ‘Descarted Error: Emotion, Reasonand the Human Brain’ 1994)
