From use cases to users perspectives

  1. 1. From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Mario Chiesa – ISMB; Cristina Barbero, Simona Ricaldone – Concept Reply
  2. 2. Context and motivation design and prototyping in the real world of an innovative technological platform – hardware – system architecture – middleware – applications to implement future horizontal services within the Internet of Things (IoT) paradigm From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  3. 3. Context and motivation As an example of future “horizontal” implementations of IoT technologies and services, we chose a mall with: – A parking area – Shops – Other typical services – Associated touchpoints From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  4. 4. Context and motivation “How does and how can IoT services impact and change the way people experience their city?” “How to create an IoT ecosystem that creates mutual benefit for both service contributors as well as service consumers in order to encourage active participation and long term sustainable growth of the city platform?” From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  5. 5. IoT value drivers • infrastructural values 1. simplified manual proximity trigger 2. automatic proximity trigger 3. automatic sensor triggering 4. automatic product security • motivational values 5. simple and direct user feedback 6. extensive user feedback 7. mind-changing feedback From use cases to users perspectives A process towards the definition of a tool for IoT urban service design “Simplified and automatic extensive feedbacks”
  6. 6. IoT in public urban areas • Diffused and horizontal solutions • Loose definition of goals • Users with very different skills • Multiple services at the same time, with different timescales From use cases to users perspectives A process towards the definition of a tool for IoT urban service design “very different from vertical professional environment“
  7. 7. The design challenge • How different users will perceive their interactions with IoT services? • Why they will decide to use and interact with many of them? • How their daily life will benefit from them? From use cases to users perspectives A process towards the definition of a tool for IoT urban service design “Multiple levels for motivational aspects and feedbacks“
  8. 8. The design challenge From use cases to users perspectives A process towards the definition of a tool for IoT urban service design “How can we answer to those crucial questions?“ “How can we communicate those motivations?“
  9. 9. Limits of classic design tools – 1/3 Scenarios, use cases, tasks descriptions: are linear and homogeneous ways of developing and describing stories. They usually need to ground their narration on a set of pre-assumptions (technological or motivational), develop it through a sequence of actions and events, and end with a finite set of possible conclusions. From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  10. 10. Limits of classic design tools – 2/3 As a linear narration they find difficult: • to describe multiple forks along the process • to highlight the richness in the offering of services • to describe the generation of complex services • to describe simultaneous situations and conditions, and their evolution From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  11. 11. Limits of classic design tools – 3/3 As an homogeneous narration they find difficult: • to satisfy the need of describing and representing the same event or sequence of events towards different communities • to allow the addition of future services, implementations into the same narration • to describe the same events with different eyes, according to the different involved stakeholders From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  12. 12. Inspirations – 1/4 Scenario based system design From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  13. 13. Inspirations – 2/4 From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Isometric projections
  14. 14. Inspirations – 3/4 From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Storytelling
  15. 15. Inspirations – 4/4 From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Toys
  16. 16. Plain text microstories From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Microstories can: • break a scenario in its basic units • describe a use case from more viewpoints • leave room to side descriptions and situations that typically would be lost
  17. 17. Plain text microstories From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Microstories can: • enhance the added value perceived by users – when they get in touch with the system (as a single experience) – during their usage of the system (again as a single experience) – in the long period, as an overall perception of the system as it impacts in their lives (as a global experience)
  18. 18. Microstories from existing user stories From use cases to users perspectives A process towards the definition of a tool for IoT urban service design developing microstories means to break apart each use case into several microstories, in order to create: • at least one single experience microstory for each step in the use case • at least one global experience microstory for each use case or usage scenario
  19. 19. Microstories from investigation phase From use cases to users perspectives A process towards the definition of a tool for IoT urban service design developing microstories means to translate into its narrative form the results of a clustering session, in order to create: • at least one single experience microstory for each item of a cluster • at least one global experience microstory for each cluster
  20. 20. Microstories, time perspectives and roles From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Final users Providers Global experience Personal achievements, global considerations Business goals, overall evaluations Single experience Single actions, local advantages Single actions, local advantages
  21. 21. User perspectives From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  22. 22. Instant perspectives From use cases to users perspectives A process towards the definition of a tool for IoT urban service design “The next step in the visual representation of the microstories is their visualization in the real use context“
  23. 23. Instant perspectives – work in progress From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  24. 24. Instant perspectives – work in progress From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  25. 25. A glimpse of other project’s activities From use cases to users perspectives A process towards the definition of a tool for IoT urban service design XMPP • Ad-hoc commands • Publish-subscribe • Data forms IoT Middleware
  26. 26. A glimpse of other project’s activities From use cases to users perspectives A process towards the definition of a tool for IoT urban service design
  27. 27. From use cases to users perspectives A process towards the definition of a tool for IoT urban service design Mario Chiesa Istituto Superiore Mario Boella chiesa@ismb.it Cristina Barbero, Simona Ricaldone Concept Reply {cr.barbero, s.ricaldone}@reply.it Thank you!
