Introduction to HCC and HCM

Human Centered Computing

Philosophical-humanistic position regarding the ethics and aesthetics of a workplace

Any system that enhances human performance

Software design process that results in interfaces that are really user-friendly

HCC

HCC research focuses on all aspects of human-machine integrationHumans with softwareHumans with hardwareMachine-Machine interaction e.g. software

agents.

Scope of HCC

Goes way beyond user friendly interfaces. Uses 5 technologies in a synergesic way. Natural interaction,

automation, individualized information access, collaboration and customization.

Core of HCC system and algorithm design process Socially and culturally aware. Directly augment or consider human abilities. Be adaptable.

HCC Application Qualities Act according to the social and cultural context in which they

were deployed. Integrate input from different types of sensors and

communicate through a combination of media. Allow access by a diversity of individuals.

Scope of HCC - AcademiaHCC doctoral program at Georgia Tech

Bridge gap between technology and humans. Integrating concepts from anthropology, cognitive

sciences, sociology psychology with computing and computer science.

HCM – Human Centered Multimedia

Three key factors in the development of future computing systems:

cultureintegration of sensors and multiple

media.access outside the desktop by a wide

range of users.

HCM….

Multimedia technologies are key in accessing the world’s resources, particularly if we extend our notion of multimedia to what it really is—A combination of digital, analog, spatial, and

sensory inputs and outputs.This leads to ubiquitous computing.

HCM – Cultural Factors

Cultural factors plays an important role in human–human

communication because the way we generate signals and interpret symbols depends entirely on our cultural background

The contrast is even greater in film: colors, music, and all kinds of cultural signals convey the elements of a story. Consider the differences between Bollywood and Hollywoodmovies (colors, music, story structure, and so on).

Content is knowledge, and to make this knowledge widely accessible, we must develop culture specific automatic analysis techniques.

HCC, HCI, and Human Computation

HCC - conceived as a theme that is important for all computer-related research.

HCI - The study of interaction between people and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at

the user interface (or simply interface), which includes both software and hardware

HCC, HCI, and Human Computation

Human Computation The computer asks a person or a large

number of people to solve a problem, then collects, interprets, and integrates their solutions

HCC and human-based computation approach computing from two different perspectives, they both try to maximize the synergy between human abilities and computing resources.

Can this synergy be really possible, and if it is then can we really create a ….
