Communiplay: A Field Study of Public Display Mediaspace by Jorg Muller
- multiple interactive displays linked across varied public spaces; how will people interact with displays in public media spaces?
- key metric: conversion rate – percentage of people that start interacting; also explore the honey-pot effect
- Communiplay: 6 locations in public parts of buildings; six conditions including fake users
- observations: 1,234 interactions out of 30,888 passers; honey pot effect exists, local and remote, and more participants leads to more; local is much stronger; fake users didn't show differences; interaction duration increases with more users; play together and with objects, waving, punching/kicking, mimicking; ghost effect – remote passer by local turns around; landing effect – pass then return and do a small interaction
P-LAYERS – A Layered Framework for Public Displays by Nemenja Memarovic
- many more interactive displays today, and growing; people like them especially when well executed; what are the design attributes for a successful one?
- 3 different installations with different attributes
- hardware layer: use same hardware in lab and production, communicate affordances on screen, hardware failures and support issues
- system architecture: consider scalability, keep up with 3rd party APIs
- content: user-generated and auto-generated perform the same, keep content fresh and relevant
- system interaction: skipped for time
- community interaction design: communicate value prop to the user, avoid effects of competition, guilt, and other negative impacts
- interplay between layers, self-reflection on individual awareness and interests, tabulating issues, understand effort required at each layer
Posting for Community and Culture: Design of Interactive Digital Bulletin Boards by Claude Forth
- what types of content are on non-digital boards, how do they impact the community? classify postings
- 59 bulletin boards, 1,297 postings
- findings: geographic relevance, contextual relevance, aesthetic aspects; postings were highly local; postings highly related to the purpose of the place where board is located such as cultural or entertainment; more personal ads on outdoor and commercial boards; affordances are important to cause action; tangibility and texture; lighting and contrast; controlled boards were much more neatly arranged than uncontrolled; empty boards stay empty, messy ones change often; spill beyond board surface; modern spaces don't have boards, so no community or ownership; retail shops have boards with their own identity
- conclusion: physical and local instead of virtual and global
I Can Wait a Minute: Optimal Delay Time for Public Display Content by Miriam Greis
- many boards don't yet have user-generated content yet; often only in university settings
- does it need moderation? risk of innapropriate content; what delay would be tolerated and what effects does it have?
- expectations: 83% of participants think moderation is needed, but expect to appear instantly; without moderation, willing to wait 1 minute, with informed of moderation 60% would wait longer
- research app: display 12 recent tweets to handle; no notice of moderation; 0, 30, or 90 second delays; 519 messages from 95 users
- findings: longer delays led to less posting, but didn't affect likelihood of additional postings
