People do not have a need to make a phone call!

But they might rather want to feel related!

The enjoyment comes from various sources like… "!

•! …Autonomy – “I can do what I want, the way I want it”!Independence, freedom, ideals!

•! …Competence – “I am good in what I do”!Performance, control, challenge, skills!

•! …Relatedness – “I feel close to the people I care about”!Family, romance, presence, immediacy, emotional expression!

or… "!

•! …Stimulation – “I was experiencing new activities”!Curiosity, mystery, play, coincidence, novelty!

•! …Popularity – “I have impact on what others do”!Power, status, recognition, fashion, helping!

•! …Security – “I’m safe from threats and uncertainties”!Order, calmness, familiarity, routines, relaxation!

…Physical thriving – “I’m healthy and physically active”!…Meaning – “My activities have a deeper meaning”!…Competition – “I’m better than others”!…Collecting – “I’m preserving meaningful objects”!

We can think of products as experience enablers…!

…that allow us to achieve goals!

Challenges in early concept evaluation!

•! Abstract nature of concepts!•! What are the critical issues that need to be discussed? Which are

the relevant questions to ask?!•! How to engage participants, making evaluation more fun?!•! How to support participants to talk about their expectations,

experiences, emotions and values?!•! How to obtain data on perceived use value, that also provides

inspirations and new (surprising) knowledge?!

Motivation for a new approach!

•! Abundance of methods for studying users’ experiences with products but those addressing concept-level products are rare "(see Vermeeren et al 2010) !

•! Majority of concept evaluations are done by experts!•! Lack of universally applicable user-evaluation approaches

concerning user experience!•! Di#culty in understanding peoples references when they make their

evaluations!•! Challenge of transferring user-data into design recommendations!

The AXE approach!

•! AXE stands for Anticipated eXperience Evaluation!•! AXE is a qualitative method that gives an initial perspective on the

user experience for a product or a service. !•! It involves singular users in an interview setting. The method builds on

using visual stimuli to make evaluation participants imagine a use situation and to reveal their attitudes, use practices and valuations.!

•! AXE is both an evaluative method and a method for collecting inspirations for improving the product concept. !

•! The results connect perceived product attributes with di$erent dimensions of user experience!

The AXE tool!

•! AXE is based on the idea of projective techniques - it makes use of ambiguous stimuli to help participants express their attitudes, opinions and beliefs towards the product concept.!

•! AttrakDi$2 (Hassenzahl 2003) served as base for the tool!

•! designed to display semantic di$erentials visually!

•! a tool conceived for evaluation interviews!

•! developed and iterated in several studies !

Concept briefing!

•! Overall concept description!•! Early concept narratives in second person singular form!•! Illustrations, mock-ups, paper prototypes etc… !•! All material visible to the participant at any time, to avoid

misunderstanding and as reference!

Interview process!

•! Familiarizing participants with evaluation procedure!•! participants are asked to indicate which of the presented images he/

she more closely associates with the concept in question.!•! choices serve as a platform for the facilitator to start a conversation

around the concept. (e.g. why the participant associates the concept more with image A instead of image B)!

•! facilitator asks continuation questions that probe deeper into the choice and establish a connection between attributes and consequences!

•! Indication of preference to understand participants evaluation of concept!

Analyzing data!

•! Subsequent to interviews data is transcribed!•! Partitioned into manageable segments!•! Each segment should carry a single observation!•! An observation can be, for instance, an expression of attitude

towards the concept, claim about a function or a comparison between two attributes.. !

!(p) “This image reminds me of calmness. I don’t think this concept is very calm. If it didn’t send push notifications, it would be calmer and I would like it more.” !

Use context

Summing-up!

•! Experiential aspects of products are elusive, both because they are di#cult for users to express and they are di#cult for researchers to interpret. !

•! di#culties can be attributed to the use of language itself and some to the abstract nature of both concepts and experiences !

•! Using visual stimuli as a starting point for evaluating a concept has proven itself a very viable option !

•! The analytical framework for AXE was formed through multiple iterations and extended throughout the process!

•! Analyzed data can be easily communicated to design teams as it links concrete product features with associated attributes.!

•! Understanding users’ expectations provides rich insights and inspirations for improving and redirecting product concepts!
