CHAPTER 4: UNIVERSAL DESIGN
describe universal design
define multi modal interaction
describe accessibility in user interface
biometric access control VS narrator
impacts of emerging technologies
7 principles of universal design
mobile computing VS wearable computing
alternative modes
about designing systems so that they can be used by anyone in any circumstance
the process of designing products so that they can be used by as many people as possible in as many situations as possible
3.Simple and intuitive to use
4.Perceptible information
2.Flexibility in use
1.Equitable use
5.Tolerance for error
6.Low physical effort
7.Size and space for approach and use
Providing access to information through more than one mode of interaction is an important principle of universal design
touch in interface
handwriting recognition
sound in interface
gesture recognition
Accessibility features in user interfaces
Biometric Access Control
Fingerprint, Palm Scan, Hand Geometry, Iris Scan, Signature Dynamics, Keyboard Dynamics, Voice Print, Facial Scan, Hand Topography
MOBILE COMPUTING
Systems running on small, lightweight computing devices
Small Storage Capacity
Low Power
Portability
Small User Interface
Facilitates high level of mobility
Risks to Data
Allows user to access information while moving through physical space
WEARABLE COMPUTING
is always with the user and always interacting, completely intertwined with the user.
Facilitates high level of immersion into virtual space and mobility
Allows the user to explore virtual environments and see the real world with virtual objects superimposed
should be a continuation of its user, working like a natural part of the body, not an external apparatus
lengthening of human life, the development of artificial intelligence and the enhancement of human sensory perception
regulatory entities such as the Federal Trade Commission monitor the financial impact of emerging technologies on impact of emerging technologies on

Access
Access Controls
The security features that control how users and systems communicate and interact with one another.
The flow of information between subject and object
An active entity that requests access to an object or the data in an object
A passive entity that contains information
