iMinds The Conference 2012: Lieven de Marez

  1. 1. Future Media Technologies - The user perspective Prof. dr. Lieven De Marez iMinds-MICT-UGent Digital Society dept.15/11/2012 1
  2. 2. How come it goes so slowly when it goes so fast?15/11/2012 2
  3. 3. Challenge 1: monitoring adoption & use increasing # multiscreen households 2012: we crossed ‘the chasm’ towards a multiscreen society (ito adoption) Laptop & DTV > 80% flatscreen TV 77% tablet 27% (13% in 2011) smartphone 40% (~mobile data subscription) 15/11/2012 3
  4. 4. Challenge 1: monitoring adoption & use use patterns in multiscreen households Progressive TraditionalAudience segmentation 1.0 1/10 Low Intensity N: 1500, AV content Prime Time CONTENT 47% 0.5 Status Quo x DEVICE 14%Substitution x CONTEXT Multispace-solo 59% 12% 6/10 Dimension 2 0.0 57% Unispace-social Informative Multispace-solo/social 26%Potential for 2nd screen? Extension 29% High Intensity -0.5 29% Omnivorous VRT 27% N: 245 tablet users 3/10 -1.0 -0.6 -0.3 0.0 0.3 0.6 Dimension 1 Object classes Text classes Socio-spatial context classes 15/11/2012 4
  5. 5. Challenge 1: monitoring having a 2nd screen ≠ using it as 2nd screen 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 2 15/11/2012 5
