Mobile TV

Notes de l'éditeur

1. Presentation to the Mobile HCI 2006 Conference workshop on Mobile TV. The workshop was cancelled but here’s the presentation anyway - aren’t we nice. The research paper that accompanies this presentation can be downloaded from: http://research.nokia.com/people/jan_chipchase/MobileTV_PersonalTV_vFinal.pdf. More information on each of the use cases can be found here: http://research.nokia.com/people/jan_chipchase/JanChipchase_MobileTVUseCases_External_vFinal.ppt With thanks to the full team: Boreum Choi, Jinwoo Kim and Jieun Yoon.

5. This is what was advertised on the market… Photos: Seoul, 2005. Jan Chipchase.
6. And these are the three handsets owned by our study participants. Most had the handset on the left, which if we go back to the advertisement….
7. … has pride of place in the advertisement – and is most heavily pushed by the carrier…
8. Here’s a short clip of mobile TV use in practice…
9. In the study we spent time with the participant in the everyday contexts that they did they things they did… Photos: Seoul, 2005. Jan Chipchase.
10. Whether it was using public transport… Photos: Seoul, 2005. Jan Chipchase.
11. … to where they browsed media content in the physical or the online world… Photos: Seoul, 2005. Jan Chipchase.
12. … and always ending up conducting interviews in the home… Photos: Seoul, 2005. Jan Chipchase.
13. So where did our participants watch mobile TV?
14. Surprisingly they spent a lot of time watching Mobile TV in the home… especially the bedroom… Photos: Seoul, 2005. Jan Chipchase.
15. Surprisingly they spent a lot of time watching Mobile TV in the home… especially the bedroom… Photos: Seoul, 2005. Jan Chipchase.
16. And also during the evening commute… (photo shows PDA user watching video whilst resting the device on his arm). Photos: Seoul, 2005. Jan Chipchase.
17. Well, OK, during the commute, but not like this. Watching TV like this is a pain – it takes too much effort to support the TV [if you don’t believe me hold your hand in front of your face for a minute]
18. Yes, mobile TV watching during the commute is much more likely to be like this… the participant is seated, the arm is supported on the lap and his bag is secure with his arm resting on it… bag is more secure resting on lap…. Photos: Seoul, 2005. Younghee Jung.
19. Another use case is micro-breaks… those short periods of down-time between other activities… Photos: Seoul, 2005. Jan Chipchase.
20. Except that its not strictly true because… it takes a while to connect to the TV signal…
21. So we use the term macro breaks
22. Can anyone tell me what this is? The last use case is this… (the photo is from Brighton in the UK – but is fine for demonstration purposes) Photos: Brighton, 2005. Jan Chipchase.
23. Our younger school age participants gave examples of secret use – in the classroom and library tucked inside a glasses case, or tucked inside pencil case. We can easily see the same thing happening in meetings or boring presentations (like now for example)
24. So what motivated our participants to use Mobile TV in these contexts…
25. Killing boredom… in the car whilst waiting for girlfriend who has a hospital appointment… (cars are also good because they have a power source) Photos: Seoul, 2005. Cui Yanqing.
26. And there’s novelty of course (this photo is from Japan, but you get the point). And yes, it’s a customized non-Nokia phone. Photos: Tokyo, 2005. Jan Chipchase.
27. Then there’s a desire to be first – so its just one of a number of things, whether it’s an iPod Nano or PSP Photos: Seoul, 2005. Younghee Jung.
28. So killing boredom, novelty and desire to be first…
29. Can you base a sustainable business on this…
30. Who pays for the service. Do they even know they are paying for the service? One participant managed to get her mother to pay for the subscription by telling her she would watch the education channel…
31. This is what people are used to… Photos: Seoul, 2005. Cui Yanqing.
32. And this is what is advertised… Photos: Seoul, 2005. Jan Chipchase.
33. But the screen size is actually this… Photos: Seoul, 2005. Jan Chipchase.
34. Current devices are bulky. Definitely carried in bags, and not in pockets (which is fine for women who tend to carry their mobile phones in bags anyway), but for guys they need to shift the device from pockets to bags… Yes, device size reduces over time. Photos: Seoul, 2005. Younghee Jung.
35. Coverage was an issue – for example not getting a good reception everywhere in the bedroom, and then with an antenna… Photos: Seoul, 2005. Jan Chipchase.
36. And given that its images and audio – need to have headset in place to appreciate it. Setting up a headset can be non-trivial, especially if you don’t have both hands free… Photos: Seoul, 2005. Younghee Jung.
37. But probably the killer in Korea is that there is a real lack of decent TV content (though there was excellent radio) Photos: Seoul, 2005. Jan Chipchase.
38. And this is a common site – because watching TV chews up the battery life. Photos: Seoul, 2005. Jan Chipchase.
39. In home (bedroom use)… watching mobile TV occurs with the device plugged into nearest available power socket… Photos: Seoul, 2005. Cui Yanqing.
40. The position for the phone being charged overnight and positioned for alarm clock use is about here…
41. But for watching TV – the cable needs to stretch to here…
42. So people carry spare batteries, but don’t know if they are charged or not… Photos: Seoul, 2005. Jan Chipchase.
43. Power isn’t necessarily a problem But in Korea there are good options for charging when out and about… Photos: Seoul, 2005. Jan Chipchase.
44. And also channel changing takes time… Photos: Seoul, 2005. Jan Chipchase.
45. Here’s an example [try not to fall asleep]
46. Different contexts have different watching and seating positions (lean back, lean forward, …) Photos: Seoul, 2005. Cui Yanqing.
47. Is the device still a mobile phone?
48. TV content is considered public (anyone can get it), whereas the other content on the phone is mostly private. Whilst you might or might not choose to share your private content with friends, with TV there is a set of assumptions of what can and cannot be shared… Photos: Seoul, 2005. Cui Yanqing.
49. And is it television?
50. And on the assumption that people might be willing to pay for rich experiences… We were interested in understanding whether it was possible to have an immersed viewing experience on such as small screen (and came to the conclusion that you could – if the content was appropriate)
51. But more to the point, given the contexts of use, is it desirable to have immersive experience Photos: Seoul, 2005. Cui Yanqing.
52. And given that so much of use was actually in the home…

55. Especially in the bedroom Photos: Seoul, 2005. Cui Yanqing.
56. And the practical limitations of use whilst truly mobile Photos: Seoul, 2005. Jan Chipchase.
