What are we looking at?

What• Enhance user’s skills to quit

smoking

Where• Everywhere

Why• Smoking represent health

risks

How• Wearing a portable device

that collects user’s physical and cognitive data

Our focus

Problem Scenario

A participant interacting with our (pseudo) systemOur (pseudo) system provided the real time feedback on the user’s action

Interviewing the participantArrangement of user evaluation: (pseudo) system in the left

Issues faced during setting up• Where to place our ‘pseudo’ digital prototype?• How much to support the participants?• How to keep the novelty experience when all the users are

present?• How to create the testing environment with non-users of the

system?

Study Findings • Every participant had a different notion of the system’s

interactions• Participants were unable to recall the system’s interactions• Thinking aloud (speech) was considered as an input modality

to the system• Waiting was found confusing• Using hand as an interactive space is tricky• Relevance of the tasks was unclear

Conclusion• Using hand as an interface has different implications• Simulation through ‘Wizard of oz’ is challenging• Limitation of lab based testing
