I can wait a minute

Abstract

Public displays have advanced from isolated and non interactive "ad" displays which show images and videos to displays that are networked, interactive, and open to a wide variety of content and applications. Prior work has shown large potential of user-generated content on public displays. However, one of the problems with user-generated content on public displays is moderation as content may be explicit or troublesome for a particular location. In this work we explore the expectations of users with regard to content moderation on public displays. An online survey revealed that people not only think that display content should be moderated but also that a delay of up to 10 minutes is acceptable if display content is moderated. In a subsequent in the wild deployment we compared different moderation delays. We found that a moderation delay significantly decreases the number of usergenerated posts while at the same time there is no significant effect on users' decision to repeatedly post on the display.

Using Pervasive Displays to Aid Student Recall -Reflections on a Campus-Wide Trial

“…The authors developed and deployed a web-based application on a display located on the university campus that allowed students to tweet images to the display that were shown after a short delay introduced by the moderation process. We believe that both [15] and [11] are examples that express the potential of increasing the value of displays to viewers by delivering more relevant content -our deployment follows in this pattern by having users of the system (students) contribute to content generation to increase relevance.…”

“…The results show that participants considered public displays as the most appropriate medium for posting and viewing news and events, similar to the kinds of content that could also be found on social media pages of communities. In a further example, Greis et al [11] investigated viewer expectations of content moderation delays for user generated content. The authors developed and deployed a web-based application on a display located on the university campus that allowed students to tweet images to the display that were shown after a short delay introduced by the moderation process.…”

“…However, to what extent these technologies actually support and enhance learning is still poorly understood [14]. This is particularly true for pervasive displays -whilst campus deployments of such displays are not uncommon [11,15,21], there is little empirical evidence on the role and usefulness of pervasive displays to enhance and improve learning.…”

Scheduling Content in Pervasive Display Systems

“…Should unknown content be introduced into the network, all expected that moderation would be required. Greis et al [38] found that passers-by also expect content pre-moderation, and would be prepared to wait for up to 10 minutes for their content to be approved. However, their in-the-wild deployment found that pre-moderation significantly lowered the number of content items posted.…”

“…Given the above, we formulate three further requirements to support open display networks: [38] proposes community-based flagging of inappropriate content, or at least to provide information on how content is moderated and how long the average wait should be. As an alternative, Davies et al [24] propose the use of trusted applications that offer their own moderation.…”
