Investigating the Effect of Relative Time Delay on Companion Screen Experiences

Chua Wei Liang Kenny, Jacob M. Rigby, Duncan P. Brumby, Vinoba Vinayagamoorthy
2017 Adjunct Publication of the 2017 ACM International Conference on Interactive Experiences for TV and Online Video - TVX '17 Adjunct  
In this study, 18 participants watched a nature programme while being shown companion content on a tablet. Temporal synchronisation of content between the devices was varied.  ...  This suggests that poor content synchronisation can produce a negative companion experience for viewers and should be avoided.  ...  We were primarily interested in the effect of injected delays between the TV and the tablet, while presenting a supposedly synchronised companion screen experience.  ...

One example is second screen companion apps that offer extra information about a television program, often synchronized with what happens on screen.  ...  In this paper, we investigate a second screen companion app, from the perspective of the viewers and producers of such apps.  ...  ACKNOWLEDGMENTS The research leading to these results was carried out in the TV-Ring project (EC grant agreement ICT PSP-325209).  ...

Therefore if you can't get them to go together again, there must be a reason. By all means, do not use a hammer."  ...  Finally, we use the timing residuals of one very stable source (PSR J1909-3744) as a reference against which we time PSR J1713+0747 with a root-mean-square precision of 133 ns, amongst the best timing  ...  Shapiro delay or its non-detection were used to constrain all but two of the binary pulsars in our source list. We measured annual orbital parallax in PSR J0437-4715 and PSR J1713+0747.  ...
