Investigating the effect of relative time delay on companion screen experiences

Mobile devices are increasingly used while watching television, leading to the development of companion apps that complement the content of programmes. A concern for these applications is the extent to which companion app and television content need to be temporally aligned for live synchronisation. 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. Participants completed questionnaires measuring immersion and affect and were tested on their recall for companion app content. While there were no statistically significant effects on these measures, qualitative interviews with participants after viewing consistently revealed that longer 10s delays in content synchronisation were frustrating. This suggests that poor content synchronisation can produce a negative companion experience for viewers and should be avoided

Measuring Audience Responses of Video Advertisements using Physiological Sensors

The selection of the audio track, the best timing to overlay the logo, and the overall duration, all these issues affect the effectiveness of immersive media. Since traditional methods to evaluate the user experience of potential consumers (e.g., surveys or eye tracking) have severe limitations, we used data gathered from physiological sensor to measure the viewers’ watching experiences. In this paper we report how we used our own Galvanic Skin Response (GSR) sensors to measure audience experience for the two different audio tracks of a commercial. Our results show that our GSR technology can play an important role for the advertisement community. In contrast with surveys, using GSR data relevant results can be obtained even with small number of participants, and the viewers’ experiences are more vividly visualized. This enables advertisers to, for example, be able to decide the proper length of a commercial
