  3. 3. HIPPOCAMPUS Project (I) Mental health is a key issue facing adolescents across Europe One in five children and adolescents in the EU suffers from developmental, emotional or behavioural problems (CAMHEE report, 2009) Those not yet exhibiting clear mental health issues related to chronic stress or anxiety not appear in the statistics
  4. 4. HIPPOCAMPUS Project (II) Chronic stress and other issues affects their intrinsic motivation to engage in any activity It especially important to provide children and young people with approaches to self-management of stress
  5. 5. HIPPOCAMPUS Project (III) Promoting Mental Health and Wellbeing among Young People through Yoga Call: European Union. Erasmus + KA2 – Cooperation and Innovation for Good Practices. Strategic Partnerships for Youth Reference: 2017-2-ES02-KA205-009942 Budget: 192.914€ Dates: 01/10/2017 - 30/11/2019 Coordinator: GRIAL Research Group https://hippocampusproject.eu
  6. 6. HIPPOCAMPUS Project (IV) It aims to address these issues by promoting the well-being of young people through the practice of a range of techniques derived from yoga Yoga is not always accesible to all young people due to a variety of financial and other reasons
  7. 7. HIPPOCAMPUS Project (V) O1. A programme to introduce yoga-based practices in youth contexts such as formal education contexts or associations O2. A mobile app both for iOS and Android in order to give yoga teachers in formal education contexts
  8. 8. Yuva Yoga app (I) • https://yuvayoga.org • The app is part of the pilot experiences carry out in different schools involved in the project • It is a tool for supporting the programme and providing opportunities for participants to continue their practice at home, in addition to the sessions contained in the programme Alfa: March 2018 Beta: July 2018 1.0: December 2018 1.2: June 2019
  9. 9. Yuva Yoga app (II) • A native development approach was selected, to ensure a certain quality and the proper functioning of the app • Based on Backend as a service (BaaS) • To support all offline content related to yoga practices, it was necessary to use local offline databases in client applications
  10. 10. Yuva Yoga app (III)
  11. 11. Yuva Yoga app (IV) • There are more than 100 activities and 15 sessions included in the app • The main elements of the app are yoga activities that are postures (asana), meditations, reflections and breath (pranayama) • Available in English, French, Italian, Norwegian, Spanish
  12. 12. Yuva Yoga app (V) • The classroom supports the communication of teachers, educators or yoga instructors with young people. • A virtual space for each group of students that they work with and send them different kind of sessions
  13. 13. Methodology (I) • The heuristic evaluation is a usability engineering method for finding the usability problems in a user interface design • Two phases, one focused on iOS client and other on Android client • This study is focused on iOS evaluation
  14. 14. Methodology (II) Participants • The heuristic evaluation was carried out by four experts, one woman and three men between 32 to 55 years old • None of the experts had used the app previously due it was available publicly less than one month before carried out the evaluation E1: Web developer & Researcher focused on technological ecosystems (10 years) E2: Java developer expert & HCI teacher (30 years) E3: Professor and developer of graphical user interfaces (20 years) E4: Professor & researcher focused on data visualization (20 years)
  15. 15. Methodology (III) Instrumentation The same template was provided to the experts in order to get the reports to perform the heuristic evaluation 1 indicates that the expert detected a huge amount of serious problems and 10 no problems (or low number of non-serious problems) were found Heuristic rules (Nielsen, 1994) Points (0-10) Comments Visibility of system status Match between system and the real world User control and freedom Consistency and standards Error prevention Recognition rather than recall Flexibility and efficiency of use Aesthetic and minimalist design Help users recognize, diagnose, and recover from errors Help and documentation
  16. 16. Methodology (IV) Study design and data collection • According to Nielsen the evaluators decide on their own how they want to proceed with evaluating the interface, but in this process, the researchers provided a set of guidelines and a report template • The responsibility to organize how to fix the problems fell in the developer associated with the project
  17. 17. Heuristic evaluation (I) Experts detected problems associated with all heuristic rules Heuristic rule E1 E2 E3 E4 HR1: Visibility of system status 9 10 6 8 HR2: Match between system and the real world 10 10 9 8 HR3: User control and freedom 10 10 8 8 HR4: Consistency and standards 3 10 8 7 HR5: Error prevention 7 10 10 7 HR6: Recognition rather than recall 9 8 10 7 HR7: Flexibility and efficiency of use 10 10 10 7 HR8: Aesthetic and minimalist design 9 10 10 10 HR9: Help users recognize, diagnose, and recover from errors 10 10 10 6 HR10: Help and documentation 5 10 10 5
  18. 18. Heuristic evaluation (II)
  19. 19. Heuristic evaluation (III) HR4 Consistency and standards • 16 usability problems were detected, most of them are inconsistences related to yoga terms and words used to talk about the contents • E1: “The classroom screens have different design than other parts of the app “ • E3: “An issue related to the good practices of iOS interaction, the configuration icon should be always available”
  20. 20. Heuristic evaluation (IV) HR10 Help and documentation • Few usability problems, but most of them are serious • There are no help documentation available in the app or in an external website • The yoga terms in the app are not explained (program, session…) • No information about where are the settings
  21. 21. Heuristic evaluation (V) HR1 Visibility of system status • Several usability problems with different severity rating according to the time needed to solve them • E4: “the user does not have a notion of the elements of a session. When the cards are piled, there is no way for the user to understand how many parts of the session have been completed and how many are remaining”
  22. 22. Heuristic evaluation (V) HR1 Visibility of system status • E3: “It is not possible to control the videos player inside each activity” • E1: “The visualization of activity stats in the profile is useful but if you want to know exactly which is the percentage of activities that you practice is not possible”
  23. 23. Heuristic evaluation (VI) E1: Web developer & Researcher focused on technological ecosystems (10 years) E2: Java developer expert & HCI teacher (30 years) E3: Professor and developer of graphical user interfaces (20 years) E4: Professor & researcher focused on data visualization (20 years)
  24. 24. Conclusions • The app is designed to be used to guide personal yoga practice with appropriate sessions and activities • Yoga teachers can also use the app to help their students maintain their practice between sessions • Several authors affirm that the perception of evaluators in using heuristic evaluation method is not consistent with the users' experience with a system
  25. 25. Conclusions • The low number of problems have been taken into account to develop a new minor version of the Yuva Yoga app (1.2) • It is important to highlight that the heuristic evaluation for iOS has influenced in the Android client, because the functionality is pretty similar, although interfaces in iOS and Android have differences • It is also required to apply an empirical method to get information about the use of the app by the final users (teachers, yoga instructors, educators and young people)
