Challenge 1: monitoring adoption & use increasing # multiscreen households

2012: we crossed ‘the chasm’ towards a multiscreen society (ito adoption)

Challenge 1: monitoring adoption & use use patterns in multiscreen households

N: 245 tablet users Low use for online video/live TV on tablet TV is relaxing > demanding Distraction > interaction

Problem 1: awareness Problem 2: QoS - QoE

Challenge 1: monitoring having a 2nd screen ≠ using it as 2nd screen

Challenge 2

4 scenarios

Preference for fluent video playback, even if this means lower

video quality

Challenge 2: What determines Experience? Bridging QoS-QoE gap & Reveal tipping points

De Pessemier, T., De Moor, K., Joseph, W., De Marez, L. and Martens, L. (2012, early access article). Quantifying Subjective Quality Evaluations for Mobile Video Watching in a Living Lab Context. IEEE Transactions on Broadcasting, Doi: 10.1109/TBC.2012.2199590

Suppose you revealed tipping points for different QoS-QoE relations for different profiles ….

Challenge 3: aggregation in the cloud aggregation in a cloud-based QoE agent

What people say … + what people do … (logs,

context, QoS, …) + what people have done …

Increased user concern : ‘control’ over profile …
