    Hi Rob, thank you for your question. It's 'only 18 interactions' out of all recorded interactions on the screen.
    These add up to 83 (44+8+2+6+23) -
    the majority of interactions did not help to solve the task.
    It might be interesting to point out that some people interact more; they play around in a trial and error fashion till they get it right which leads to 'failed interactions'. A different more conservative type of user interacts less and attempts to solve the task directly.

    Thanks for your suggestions.
    Frank

  • Great study, except I was confused on one detail: Slide #13 says 'users mostly accidentally call the number // only 18 correct interactions.' Is this 18 interactions out of X total interactions? I first thought 18 (out of N=20) is a majority!

    I do agree with general takeaway that the Samsung is just as good (or better) than an iPhone user experience, but most people approach it with a brand bias. However, I'm not sure the given task - save an unknown phone number to address book - is a common interaction. The most common for a missed call, is to return the call and say something like 'hello, I don't know who was calling but I just missed this call.' I just wanted to offer that.

    Thanks for an interesting study :)

Transcript of "iPhone vs. Samsung Galaxy S II - User Experience Case Study (English)"

  1. 1. iPhone vs. Samsung GalaxyA User Experience Case Study
  2. 2. The Study Set Up & Test phonesUser Experience Evaluation using Eye Tracking, i² BrandREACT and an online survey.Sample: N=20; Age: 25 – 45• 10 ordinary mobile phone users (non smartphone users)• 5 iOS (iPhone) users• 5 Android users Eye TrackingTest Design: Within Subject Design - each respondent evaluates both smart phones.Simulation of a daily situation to compare the user experience of the iPhone 4 and the Samsung Galaxy S2. Task Scenario Apple iPhone 4 You have received a missed call from an unknown number. Please save this number as a new contact, „Peter Schneider“. Samsung Galaxy S2 Apple iPhone 4 Samsung Galaxy S2 2 14/11/12
  3. 3. Key Takeaways14/11/12 3
  4. 4. Strong brand image of Apple distorts real product experience.Samsung Galaxy definitely catches up with Apple. Consumer awareness of the iPhone’s success and its reputation for usability makes users explicitly state that the iPhone is easier to use and more attractive than the Samsung Galaxy S2. On an emotional, implicit level users are stimulated by a straight forward and powerful brand image. They associate positive items faster and more often with the iPhone than with Galaxy S2. But: Eye tracking data reveals that the real user experience is not always like users say or think it is! Eye tracking and interaction tracking show scattered attention on the display. Users do not focus on the correct icons/buttons to solve the task and perform more false interactions than with the Samsung Galaxy S2. Performance data pronounces a lower success rate for the iPhone.14/11/12 4

  7. 7. Explicit: Evaluating user experience through Interviews,Thinking Aloud and System Acceptance Ratings Interview = Opinions, problems and needs of the target group are analyzed. Users are addressed on an individual level.Thinking Aloud = Users directly or retrospectively (retrospective thinking aloud) comment on theirown usage behavior. This way the user’s thoughts become more comprehensible and usagebehavior can be reflected and understood easily. System Acceptance Ratings = Evaluation of the acceptance of product features using semantic differentials and rating scales.14/11/12 7
  8. 8. Implicit: Measuring the unconscious using the i² BrandREACT.Stimulation / Power / Balance i² BrandREACT = Reaction time based tool Respondents are asked to associate certain adjectives (based on 3 emotional need dimensions) with a product/brand. Compliance rate and reaction time are measured.
