CSE5390 & 7390 Special Topics in Ubiquitous Computing lecture two, history and vision, part I Eric C. Larson, Lyle School of Engineering, Computer Science and Engineering, Southern Methodist University 1
class logistics • be sure to login to blackboard over the weekend! • remember: post summary and questions to forum • summary and questions are due for the rest of semester • keep the summary short, no more than 4 sentences • post your introduction and preferred discussions for leading during class to the forum on blackboard • due next time! CSE5390 & 7390 Special Topics in 2 Ubiquitous Computing
agenda • weiser’s early vision of ubicomp • calm technology • maybe some criticism CSE5390 & 7390 Special Topics in 3 Ubiquitous Computing
quick review alien technology? CSE5390 & 7390 Special Topics in 4 Ubiquitous Computing
quick review the metaphor? CSE5390 & 7390 Special Topics in 5 Ubiquitous Computing
papers discussion CSE5390 & 7390 Special Topics in 6 Ubiquitous Computing
the computer for the 21st century • technology is immediately recognizable, mundane • emulate: writing • glanceable • needs no explanation • easy to ignore or focus on CSE5390 & 7390 Special Topics in 7 Ubiquitous Computing
the computer for the 21st century “The state of the art is perhaps analogous to the period when scribes had to know as much about making ink or baking clay as they did about writing” is this true today? CSE5390 & 7390 Special Topics in 8 Ubiquitous Computing
the computer for the 21st century • criticism: too much focus on the box • suggest: shift focus to the task, not the tool CSE5390 & 7390 Special Topics in 9 Ubiquitous Computing
shift focus to the task • an example: medicine CSE5390 & 7390 Special Topics in 10 Ubiquitous Computing
criticism: multimedia • used to get our attention, rather than be in periphery CSE5390 & 7390 Special Topics in 11 Ubiquitous Computing
criticism: virtual reality • used to get our attention, rather than be in periphery • draws you out of everyday life CSE5390 & 7390 Special Topics in 12 Ubiquitous Computing
criticism? • used to get our attention, rather than be in periphery • draws you out of everyday life... • is this any better? CSE5390 & 7390 Special Topics in 13 Ubiquitous Computing
how to make technology vanish • metaphor: the electric motor in a car • simpler, easier installation • cheaper than system of pulleys CSE5390 & 7390 Special Topics in 14 Ubiquitous Computing
weiser’s key issues for phase 1 • a computer should know: • location • if a system knew where you were, always • scale • tabs • pads • boards CSE5390 & 7390 Special Topics in 15 Ubiquitous Computing
weiser’s key issues • a computer should know: • location does this exist today? • if a system knew where you were, always • scale • tabs • pads • boards CSE5390 & 7390 Special Topics in 16 Ubiquitous Computing
weiser’s key issues • a computer should know: • location does this exist today? • if a system knew where you were, always • scale • tabs • pads do these exist today? • boards CSE5390 & 7390 Special Topics in 17 Ubiquitous Computing
tabs? CSE5390 & 7390 Special Topics in 18 Ubiquitous Computing
tabs? CSE5390 & 7390 Special Topics in 19 Ubiquitous Computing
weiser’s tabs? CSE5390 & 7390 Special Topics in 20 Ubiquitous Computing
pads? CSE5390 & 7390 Special Topics in 21 Ubiquitous Computing
pads? CSE5390 & 7390 Special Topics in 22 Ubiquitous Computing
weiser’s pads? CSE5390 & 7390 Special Topics in 23 Ubiquitous Computing
boards? CSE5390 & 7390 Special Topics in 24 Ubiquitous Computing
boards? CSE5390 & 7390 Special Topics in 25 Ubiquitous Computing
weiser’s boards? CSE5390 & 7390 Special Topics in 26 Ubiquitous Computing
sal what happened to sal? • wakes, automated coffee • neighbor trail • kids awake notified • pen used in newspaper • foreview mirror for traffic • automated login and windows for other places • “shared” office with Joe • collaborative workspace with Joe ease of the day? computer addiction? privacy? ability to communicate? choice and diversity?

weiser’s message • ubicomp is not about creating something new, but making the unremarkable faster, easier, and more enjoyable • fit the computing to the problem, don’t fit the problem into a tool • make computing calm... CSE5390 & 7390 Special Topics in 29 Ubiquitous Computing
the coming age of calm computing CSE5390 & 7390 Special Topics in 30 Ubiquitous Computing
the coming age of calm computing CSE5390 & 7390 Special Topics in 31 Ubiquitous Computing
why calm: the eras of computing • mainframes • personal computers • internet • mobile computing • ubicomp CSE5390 & 7390 Special Topics in 32 Ubiquitous Computing
why calm: the eras of computing • mainframes • personal computers • internet • mobile computing • ubicomp if it isn’t calm, we will be utterly unfocused and inherently distracted weiser : “If computers are everywhere they better stay out of the way” CSE5390 & 7390 Special Topics in 33 Ubiquitous Computing
elements of “calm” • center versus peripheral attention • calm computing can stream naturally between them • periphery informs without overwhelming CSE5390 & 7390 Special Topics in 34 Ubiquitous Computing
the dangling string make the unseen, seen… CSE5390 & 7390 Special Topics in 35 Ubiquitous Computing
weiser’s (best?) calm example • look out for information • other’s can look in • private enough to control CSE5390 & 7390 Special Topics in 36 Ubiquitous Computing
the multicast CSE5390 & 7390 Special Topics in 37 Ubiquitous Computing
everyday calm examples? CSE5390 & 7390 Special Topics in 38 Ubiquitous Computing
research based calm examples CSE5390 & 7390 Special Topics in 39 Ubiquitous Computing
research based calm examples CSE5390 & 7390 Special Topics in 40 Ubiquitous Computing
vision: spurring discussion • when would technology be cheap enough to be disposable? is that even a good idea? • does it need to be disposable or commonplace? • power? • can the system be wrong? • is the present computing era calm? • is ubicomp necessarily clam? • what is missing from the calm model? • is anything private? CSE5390 & 7390 Special Topics in 41 Ubiquitous Computing
for next class... • do the summary and questions for discussion next week • author spotlight: Gregory Abowd • I am in CA for the rest of the week • no class on Monday (labor day) • next week : A0 due! CSE5390 & 7390 Special Topics in 42 Ubiquitous Computing
