Always Best Communication - ABC Users want to communicate with each other –Any place –Any time –Any device How can we utilize wireless networks in supporting ABC?
3
Simple Scenario Session AND device mobility –A user is late for an online meeting The system knows this from the user’s calendar –The system automatically dials the user’s mobile phone Audio participation –The user reaches her office This is noted by position awareness –The system automatically joins the online meeting and ask the user where she want the audio In the mobile, PC audio or desktop phone? User selects desktop phone on the PC screen and the call is transferred from the mobile.
4
Problems How to detect locality with good enough precision? How to swap between different wireless and fixed carriers? –Carrier mobility How to swap between devices –Session mobility How to keep the current session running?
5
Ubiquitous Human Communication
6
Imagine rich media sensors –Includes audio in (microphone) and audio out (speaker) but not necessarily in the same device –Includes video in (camera) and video out (display) but not necessarily in the same device –Not all in same device (might be 4 different) –Cheap –Doesn’t have to run on batteries –WLAN
7
Available everywhere We put these all over a work place –Offices –Corridors –Homes Use together with good enough positioning of all users Allow for “free” communication anywhere Ubiquitous Human Communication
8
Problems How to make the sensors cheap Distributed echo canceling/suppression and multi-channel audio playback Multi-view video grabbing presented –Several video views to multiple video display devices on the other side. WLAN model when using high quality video feeds (sustained 1-25Mbps per video channel and several channels). Power? –Perhaps skip WLAN and go for ethernet + power over ethernet instead?
