Video as a prototyping tool for connected products
•
1 like•146 views
Martin Charlier @ O'Reilly Design Conference 2018 This is a talk about how video is a powerful tool for rapid low-fi prototyping of connected products & the Internet of Things. This talk argues how this method is useful, shows how it builds on existing prototyping methods and gives a practical example for how you can apply this method. Finally, the talk shows how the same ideas and principles of animated or filmed artefacts can be used at different levels of fidelity and focussed on different purposes.

- 6. 6 You might learn more about user experience from a wooden block and a chop stick than from an high-tech prototype.
- 7. 7 Through early low-fi prototyping, you can ask big and fundamental questions about your product before you sink too much cost. • Would people use this? • How would it have to work to be desirable? • What would it feel like to use this? • Should we build this at all?

- 9. 9 Challenges with connected products • The interface might be controls on a new kind of device. • The interface could be non-screen based, like voice, gesture, proximity, physical interaction. • Interaction might happen across different devices, across space or time. • The overall experience doesn’t just happen on a computer or a mobile - it involves unboxing, manuals, different devices, installation… Above: Tado Thermostat Below: Jordi Parra’s Spotify Box (http://blog.zenona.com/)

- 13. 13 Conventional prototyping methods aren’t always fit for the prototyping challenges of connected products.
- 14. 14 Bootstrap HTML/CSS/JS Objective-C / Swift Software UX prototyping tools
- 15. 15 Bootstrap HTML/CSS/JS Objective-C / Swift • Software UX tools are often too screen centric too soon. • They don’t really work for Voice or Gesture UIs. • Prototyping user journeys that happen across multiple screens or devices isn’t ideal. • It’s easy to forget the physical context around the device.
- 17. 17 • Industrial design and physical prototyping methods often lack interactivity at the low-fi level. • You need electronics - this can be time-consuming. • Electronics can become a barrier quickly. • Easy to get carried away with optimisation.

- 21. 21 Video isn’t an obvious tool for prototyping.
- 22. 22 The first association for ‘video’ in design is often a polished, CGI heavy vision film illustrating a shiny, seamless future.
- 23. 23 What makes video great • Effortless to follow • Easy to share • Conveys what an experience feels like - viewers gain empathy with the actors.
- 24. 24 Dissecting video • Script/Scenes = Description of action sequence • Set = The physical context in which action takes place • Actors = Multiple humans that carry out actions or interact • Props = Physical things, mock-ups, prototypes • Special Effects = Things, actions or behaviours that don’t exist
- 25. 25 Dissecting video • Script/Scenes = Description of action sequence • Set = The physical context in which action takes place • Actors = Multiple humans that carry out actions or interact • Props = Physical things, mock-ups, prototypes • Special Effects = Things, actions or behaviours that don’t exist The user journey you iterate and develop
- 26. 26 Dissecting video • Script/Scenes = Description of action sequence • Set = The physical context in which action takes place • Actors = Multiple humans that carry out actions or interact • Props = Physical things, mock-ups, prototypes • Special Effects = Things, actions or behaviours that don’t exist How you gain (and convey) empathy with the user and their context
- 27. 27 Dissecting video • Script/Scenes = Description of action sequence • Set = The physical context in which action takes place • Actors = Multiple humans that carry out actions or interact • Props = Physical things, mock-ups, prototypes • Special Effects = Things, actions or behaviours that don’t exist Working across different touch points, interface types, spaces and taking into account multiple users.

- 36. 36 A connected fishing rod?! • It’s a way to figure out whether something is a good idea before investing much time & money.
- 37. 37 It’s more about the process than the outcome 80% (The process) • Rapid iteration and decision making. • Exploration across physical context, multiple devices, time and space. • Forces you to think in a time-based sequence of events - a user journey. • Acting out: Empathy with the user. How it might ‘feel’ like using this. 20% (The video) • It’s self-explanatory and shareable. • Film is a widely understood medium that is easily digestible. • Less ‘loss in translation’, relies less on imagination of others. • It lets viewers judge plausibility (they get a degree of empathy).
