Personal vs. commercial content: the similarities between consumer use of photos and music

We describe the results of two ethnographic-style studies that investigated consumer use of photos and music respectively. Although the studies were designed, executed, and analyzed separately, in our findings we discovered striking similarities between the ways in which our participants used personally captured photos and commercially purchased music. These findings have implications for the design of future systems with respect to handling and sharing content in photo or music form. We discuss making allowances for satisficing behavior, sharing media as a way to reminisce or to communicate an experience (tell a story), getting sidetracked while browsing, and similarities in organizing behaviors.

The uses of social television

We present the results of two studies on social television concepts. In one study, a social TV prototype was tested in the field, allowing groups of users watching television at home to talk to each other over an audio link. Specific patterns of use are described, showing that users did perceive the system as valuable. In another study, focus groups were presented with several social TV concepts, and their responses were collected. These participants saw only moderate to marginal value in the concept. We discuss the discrepancy with reference to the limitations of each method. Based on our analysis, we conclude that our social television experience provides user value under certain favorable conditions. Participants deal with potential conflicts between conversation and television audio without the need for additional technical support, and there is no indication that a video link would improve the experience. However, designing for the social dynamics at the beginnings, ends, and outside of conversations remains an open challenge.

Field trial of a dual device user experience for iTV

With the rise in highly capable, mobile and networked secondary devices, the two-screen Enhanced TV is a more plausible proposition today than ever before. This paper presents a field trial of a prototype that aimed to understand a conceptual merger of TV and second screen user experiences. Our prototype concept can be described as a companion device experience that enhances TV viewing by providing auxiliary information and media on a second screen. The additional media is semantically related and synchronized, in terms of timeline, to the TV content. We ran a three-week field trial in 11 households. Participants used our prototype as a companion to their TV shows. We provided a total of 43 episodes from 10 popular TV shows throughout the study period. Overall feedback to our concept was quite positive. 10 out of our 11 participants said they enjoyed the experience. Our prototype allowed participants to better connect with their TV shows and have an enriched social life around TV. We also report some of the discovered user desires regarding user interaction design such as kinds of customization controls needed and the pacing of posts of additional information to the second screen.

Perceptions of value: the uses of social television

We present the results of two studies on social television concepts. In one study, a Social TV prototype was tested in the field, allowing groups of users watching television at home to talk to each other over an audio link. Specific patterns of use are described, showing that users did perceive the system to be valuable. In another study, focus groups were presented with several Social TV concepts, and their responses were collected. These participants saw only moderate to marginal value in the concept. We discuss the discrepancy with reference to the limitations of each method.

Investigating the Use of Voice and Text Chat in a Social Television System

We tested a social television system with both voice and text communication in the field for one week, in four households. Participants expressed a preference for the freeform communication features over an earlier system with restricted communication options. Use of the communication features was nevertheless sporadic. Text was used more often than voice communication. However, both were usually used in combination. The in-home context had marked effects on the usage patterns, and we observed issues of privacy and identity verification.

Introduction to Social TV

Mobile TV typically involves accessing television content from handheld devices. The most ubiquitous of these devices, mobile phones, are primarily designed for communication. It is therefore natural to look at how those communication features can be integrated with television viewing. Issues of sociability are also relevant to Mobile TV in other ways, such as in analyzing how watching video in public spaces affects and is affected by the social context, and in the case of communication by video messages and video conferencing.
