A context-aware model for QoE analysis in mobile environments

  1. 1. CARIM A Context-aware Model for QoE Analysis in Mobile Environments Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez Interacci´on 2013 September Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 1 / 16
  2. 2. Agenda CARIM A Context-aware Model for QoE Analysis in Mobile Environments 1 Motivation the problem and the proposed solution 2 CARIM metamodel description of CARIM features and benefits 3 Practical overview and Conclusion working scenario, the experiment and conclusion Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 2 / 16
  3. 3. I Motivation
  4. 4. The problem When we analyze mobile interaction... some methods use cumulative values → but interaction is dynamic context matters → but context changes some methods lack structure → hinders analysis/comparison interaction data usually separated from quality perception → QoE? this hinders mobile QoE analysis Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 4 / 16
  5. 5. The solution Thus, we propose: describe interaction stepwise, using turns describe the surrounding context dynamically structure parameters to allow comparison of interaction records link quality perception to interaction records CARIM metamodel does this way Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 5 / 16
  6. 6. II CARIM
  7. 7. CARIM: dynamic description of multimodal interaction based on PALADIN1 ⇒ multimodal interaction metamodel describes communication content + metadata by turn 1 http://www.catedrasaes.org/wiki/MIM Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 7 / 16
  8. 8. CARIM: context-aware contextual factors affecting users experience with mobile apps dimensions: physical, social, location/time, device and connectivity context described by turn ⇒ dynamic environment Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 8 / 16
  9. 9. CARIM: perceived quality and cognitive state describes perceived quality using parameters of a questionnaire describes influencing factors for quality perception: users mood and attitude towards technology ratings linked to interaction ⇒ enhanced QoE analysis Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 9 / 16
  10. 10. Benefits: unified criteria same structure and metrics regardless of the execution environment provides experts and tools with unified criteria allows comparison between CARIM instances Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 10 / 16
  11. 11. Benefits: run-time nature run-time nature ⇒ relationship (data ↔ time) ⇒ running instances dynamic (stepwise) analysis of interaction real-time adaptation decisions Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 11 / 16
  12. 12. III Practical overview and Conclusion
  13. 13. Typical scenario of use More info about CARIM and the other tools: Mateo et al., http://www.catedrasaes.org/wiki/Carim Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 13 / 16
  14. 14. The experiment CARIM is in an experiment comparing 2 different interaction designs the user has to play with a Lunar Lander game, and then answer a short questionnaire we need more participants. Please, help us and join the experiment... using this QR code, or going to www.pedromateo.es/carim-experiment.html, or search for “phd experiment” in Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 14 / 16
  15. 15. Conclusion CARIM ⇒ parameter-based metamodel quantifies mobile user-system interaction describes live surrounding context includes cognitive state and quality ratings CARIM ⇒ unified criteria to describe mobile interaction comparison of QoE records; reuse of analysis tools CARIM ⇒ run-time metamodel live interaction + context → stepwise analysis; decision CARIM ⇒ ratings + interaction → enhances QoE analysis CARIM is not alone ⇒ integration framework + HCI extractor Pedro Mateo (pedromateo@um.es) Diego Sevilla, Gregorio Mart´ınez ()Model-based QoE Analysis Interacci´on 2013 September 15 / 16
