introduction Flashcards
embedded system
its main purpose isn’t to be a computer
ubicomp
human-computer interaction in which information processing is integrated into everyday objects and activities
Mark Weiser
a world in which computing and applications are integrated into everyday objects
3 formats of smart devices (Weiser)
tabs: wearable devices
pads: handheld devices
boards: interactive display devices
computing waves
mainframe: one comp-> multiple people
personal computing: 1 comp -> one person
ubicomp: multiple comp -> one person
transistor
semiconductor device, fundamental in all electronic devices
microporocessor
a chip containing millions of transistors
The law of Moore
1965, the number of transistors that can fit on a chip doubles approximately every two years (now every year)
MEMS
Micro ElectroMechanical Systems; integrates tiny mechanical elements, sensors, actuators, and electronics on a single chip, preform two functions: sensing and actuation
main job of a logical device
act as an on and off switch
sensor nodes or motes
small, autonomous devices equipped with sensors, processing capabilities, and communication interfaces
nanotechnology
engineering at very small (atomic) scales
key components in a smart system
sensors
actuators
controllers
essential features of a smart system
context awareness
intelligence
autonomy
seamless networking
implicit human computer interaction
multimodal human computer interaction
Weiser: “calm or disappearing computing”
seamlessly runs in the background
