  1. network-based interaction Alan Dix chapter for ‘handbook of human computer interaction’ (Lawrence Erlbaum)

  2. issues are networks just an ‘implementation detail’? on the other hand ... networking dominates current interaction

  3. structure • intro & types of networks • four main headings ... what is special for users about networks ... • round up • history and futures • societal effects and paradigm changes

  4. special things ... • networks as enablers • things that are only possible with networks • networks as mediators • issues and problems because of networks • networks as subjects • understanding and managing networks • networks as platforms • algorithms and architectures for distributed interfaces

  5. types of network • local vs. global • fixed vs. flexible

  6. changing focus

  7. Networks as Enablersthings that are only possible with networks • access to remote resources: • people • physical things • data • computation • applications - other chapters • groupware, mobile, e-commerce, tele-work etc.

  8. Networks as Mediatorsissues and problems because of networks • network properties • bandwidth, latency, jitter, QoS, buffering, etc. • UI properties • transparency, delays and time, consistency, races, feedback/feedthrough, awareness • media issues • delay/dropped packets, broadcast/interaction, audio/video differences

  9. Networks as Subjectsunderstanding and managing networks • network models • standard OSI-ish stuff, but high-level • network management • large scale (BT) and small scale (PC) • network awareness • exposing costs, network/resource availability • feature interaction (not quite right place?)

  10. Networks as Platformsalgorithms and architectures for distributed interfaces • locking • traditional and lightweight groupware forms • optimistic concurrency • algorithms for distributed (text) editing dOPT etc., • asynchronous replication mechanisms (Notes etc.) • architectures for networked systems • web arch, mobile arch, PoP • supporting infrastructure • awareness servers, notification servers, event/messaging systems • discovery (JINI, UPaP), mobile code, intelligent networks etc.

  11. history, paradigm and future • history • arpanet, internet, web etc. etc. ... • paradigm shift • global village, cyberspace, cross-cultural issues, e/m-commerce, charging models, PopuNET • futures (near) • ubiquitous, next-gen media etc.IPvX or mobile standards on fixed lines?
