We tested the user experience of the leap motion controller with users. It shows the great potential of gesture controls, but also some significant drawbacks. Interaction designers need to be aware of technical limitations and human expectations when deisgning apps with gesture interfaces.

Transcript

  • 1. E-motion-al or frustrating? Leap Motion put to the UX test – Gesture control from the users' point of view
  • 2. LEAP MOTION PUT TO THE UX TEST RESULT OVERVIEW ABOUT LEAP MOTION OBJECTS AND PROCEDURE RESULTS AUTHORS
  • 3. RESULT OVERVIEW
  • 4. 01. RESULT OVERVIEW BASIC INFORMATION ABOUT THE STUDY — The Leap Motion Controller is a new motion sensing technology for human–computer interaction. — UID evaluated the user experience of Leap Motion with 16 participants. — Based on the results UID draws conclusions how to design user- friendly gestural interaction. | August, 19th 2013 | Leap Motion put to the UX testPage 4 SOURCE 1)
  • 5. 01. RESULT OVERVIEW USER EXPERIENCE — Leap motion captures movement precisely and the interaction with gestures delights and simultaneously frustrates the user. — A consistent basic vocabulary of interaction gestures will facilitate the controls of the apps. — Leap Motion has a big potential to make an inspiring User Experience (UX) possible for certain use cases. | August, 19th 2013 | Leap Motion put to the UX testPage 5 SOURCE 2)
  • 6. 01. RESULT OVERVIEW REQUIREMENTS FOR THE GESTURES — For the creation of the User Experience, natural interaction like grabbing for objects and simultaneous use of both hands should be offered. — Bad or improper definition of the gestures affect a loss of control as well as frustration. Good interaction design for Leap Motion needs to be crisp and focused. As in many other Natural User Interface (NUIs), the tolerance for technical faults is very small. — New gestures, that enable more direct interaction and are not similar to traditional interaction with mouse or touch, can be learned easily and thus provide an additional benefit. — The next step will be, that we have a detailed look at a standard gesture vocabulary and discuss requirements for interesting gesture use cases. | August, 19th 2013 | Leap Motion put to the UX testPage 6
  • 7. ABOUT LEAP MOTION
  • 8. 02. ABOUT LEAP MOTION WHAT IS LEAP MOTION? — Leap Motion is a new motion sensing technology for human– computer interaction, released in July 2013. — It offers the possibility of gesture recognition (comparable with KINECT) and enables to use Windows 8 or Mac without the mouse. | August, 19th 2013 | Leap Motion put to the UX testPage 8 SOURCE 3)
  • 9. 02. ABOUT LEAP MOTION THE LEAP CONTROLLER — The Leap Controller, not much bigger than a lighter, is positioned in front of the screen and connected via USB to the computer. — It builds up an infrared field that captures the movement of up to 10 fingers (or items such as a pen). This is additionally supported by 2 small cameras. | August, 19th 2013 | Leap Motion put to the UX testPage 9 SOURCE 4)
  • 10. 02. ABOUT LEAP MOTION FIELDS OF APPLICATION — Leap is similar to "jump over" and announces a technical progress. » In the future it could replace the computer mouse and allows new forms of human-computer interaction. — The current main field of applications are apps for gaming to introduce users to control their computer via gestures. | August, 19th 2013 | Leap Motion put to the UX testPage 10 SOURCE 5)

  • 12. OBJECTIVES AND METHODS
  • 13. 03. OBJECTIVES AND METHODS OBJECTIVES OF THE STUDY — We wanted to check » the UX promises and expectations of Leap Motion, » the perceived user experience from the users » and possible use cases from the users point of view. — Based on the results of the User Experience Test we develop recommendations for designing user-friendly gestural interaction. | August, 19th 2013 | Leap Motion put to the UX testPage 13 SOURCE 7)
  • 14. 03. OBJECTIVES AND METHODS TEST SET-UP — We evaluated the Leap Motion Controller in a UX test with 16 participants. » In the UX test the participants explored the usage of the Leap Motion Controller freely, while experts of UID observed the behaviour of users and their experience. — In the second step UID measured the user experience of Leap Motion with the online tool AttrakDiff. » AttrakDiff helps to understand, how users personally rate the usability and design of interactive products: www.attrakdiff.de | August, 19th 2013 | Leap Motion put to the UX testPage 14
  • 15. 03. OBJECTIVES AND METHODS EXCURSION: WHAT IS USABILITY? WHAT DOES "USER EXPERIENCE" MEAN? — Usability (user-friendliness) is a standard to measure how easy it is for a user to interact with an interactive product. User-friendly solutions help users to accomplish their goals and tasks faster, and they increase the users' satisfaction, avoiding or reducing mistakes and frustration. — The expression "user experience" takes this whole concept a big step forward by including non- instrumental aspects of the use of a product. How attractive does the application appear? Is it fun to use this interactive product? Is motivation increased by a more intensive, creative and productive use of the product? Can users identify themselves with the product, can they relate to it and thus the manufacturer? The entire experience that a user makes with a product is what is important. | August, 19th 2013 | Leap Motion put to the UX testPage 15
  • 16. RESULTS
  • 17. 04. RESULTS FIRST IMPRESSION AND EXPECTATIONS — When using Leap Motion for the first time, every participant is happily surprised. » Participants were fascinated by the technology and emotionally engaged in the first usage. — First, participants interacted with the entire hand and didn't expect that the single fingers are captured by Leap Motion. The fact, that Leap Motion captures the movement of up to 10 fingers, was surprising. | August, 19th 2013 | Leap Motion put to the UX testPage 17 PROVIDE FEED- BACK TO SHOW PARTICIPANTS WHAT IS CAPTURED.
  • 18. 04. RESULTS GESTURES — Gestures that simulate grabbing objects, have been understood intuitively. — Gestures that are different to a mouse/touch interaction, have not been expected since the computer needs to interpret this (e.g.: showing three fingers instead of selecting "menu item 3"). » But this interactions have been learned easily and with fun. | August, 19th 2013 | Leap Motion put to the UX testPage 18 CREATE GESTURES THAT SIMULATE GRABBING AN OBJECT.
  • 19. 04. RESULTS CAPTURE OF THE MOVEMENTS — It is ambiguous in which spatial area the Leap Motion captures the movement. » Participants moved outside of the “interaction-space” and the interaction broke down. — Gestures need to be performed very precisely, otherwise they aren't recognized or are misinterpreted. » But humans do gestures with less cognitive effort, and in their own, personal way. Having to learn and practice the exact gesture, is work. It can quickly turn into (unexpected) effort. SHOW THE USER IN WHICH AREA IT CAPTURES THE MOVEMENTS. | August, 19th 2013 | Leap Motion put to the UX testPage 19
  • 20. 04. RESULTS TIRING INTERACTION — The participants generally got impatient when an interaction didn't work straightaway. » Since we use our hands to communicate and other humans will get our “gesture message” very quickly, participants had no tolerance for any misinterpretation. — The execution of gestures in the long run can be quite strenuous. » When a gesture has to be repeated several times because it is not recognized or the dialogue requires it, the strain on hand muscles is quickly displeasing. | August, 19th 2013 | Leap Motion put to the UX testPage 20 CREATE GREAT INTERACTION DESIGN SO THAT NO ONE BECOMES TIRED.
  • 21. 04. RESULTS INCONSISTENT SET OF GESTURES ACROSS APPS — There is no consistent set of gestures across the different apps. » Every app uses an own gesture-vocabulary for their interaction. » This means a constant challenge to remember gestures or learn new sets. Participants are irritated by that extra effort. NOW IT IS (Y)OUR JOB TO FIND INTUITIVE GESTURES. | August, 19th 2013 | Leap Motion put to the UX testPage 21
  • 22. 04. RESULTS ATTRAKDIFF — In the AttrakDiff Leap Motion is positioned quiet high in the topic "self-oriented" (see image). — One could say that the participants see less the practical value, but it still is a lot of fun to use Leap Motion. | August, 19th 2013 | Leap Motion put to the UX testPage 22
