Design, development and deployment of mixed initiative human computer systems

Human centered computing (HCC) studies the design, development, and deployment of mixed initiative human computer systems. It is emerged from the convergence of multiple disciplines that are concerned both with understanding human beings and with the design of computational artifacts. Human centered computing is closely related to human computer interaction and information science. Human centered computing is usually concerned with systems and practices of technology use while human computer interaction is more focused on ergonomics and the usability of computing artifacts and information science is focused on practices surrounding the collection, manipulation, and use of information. Human centered computing researchers and practitioners usually come from one or more disciplines such as computer science, human factors, sociology, psychology, cognitive science, anthropology, communication studies, graphic design , and industrial design. Some researchers focus on understanding humans, both as individuals and in social groups, by focusing on the ways that human beings adopt and organize their lives around computational technologies. Others focus on designing and developing new computational artifacts.

Multimedia production is the human task of creating media. For instance, photographing, recording audio, remixing, etc. All aspects of media production concerned must directly involve humans in HCM. There are two main characteristics of multimedia production. The first is culture and social factors. HCM production systems should consider cultural differences and be designed according to the culture in which they will be deployed. The second is to consider human abilities. Participants involved in HCM production should be able to complete the activities during the production process. The field of Multimedia in Human Centered Multimedia (HCM) is dedicated to the creation and development of various forms of media, including photography, audio recording, and remixing. What sets HCM apart is its emphasis on active human involvement throughout the production process. This means that cultural differences must be taken into account to tailor HCM systems according to specific cultural contexts. Furthermore, a key factor for achieving success in HCM production lies in recognizing and utilizing human capabilities effectively; this enables active participation and ensures efficient completion of all production activities.

Multimedia analysis can be considered as a type of HCM applications which is the automatic analysis of human activities and social behavior in general. There is a broad area of potential relevant uses from facilitating and enhancing human communications, to allowing for improved information access and retrieval in the professional, entertainment, and personal domains. The field of Multimedia Analysis in Human Centered Multimedia (HCM), involves automatically analyzing human activities and social behavior. This application area covers a wide range of domains, including improving communication between individuals and enhancing information access in professional, entertainment, and personal contexts. The possibilities for utilizing multimedia analysis are extensive, as it goes beyond simple categorization to achieve a nuanced understanding of human behavior. By doing so, system functionalities can be enhanced while providing users with improved experiences.

Multimedia interaction can be considered as the interaction activity area of HCM. It is paramount to understand both how humans interact with each other and why, so that we can build systems to facilitate such communication and so that people can interact with computers in natural ways. To achieve natural interaction, cultural differences and social context are primary factors to consider, due to the potential different cultural backgrounds. For instance, a couple of examples include: face to face communications where the interaction is physically located and real time; live computer mediated communications where the interaction is physically remote but remains real time; and non real time computer mediated communications such as instant SMS, email, etc.

The Human Centered Design Process is a method to problem solving used in design. The process involves, first, empathizing with the user to learn about the target audience of the product and understand their needs. Empathizing will then lead to research, and asking the target audience specific question to further understand their goals for the product at hand. This researching stage may also involve competitor analysis to find more design opportunities in the product's market. Once the designer has compiled data on the user and the market for their product design, they will then move on to the ideation stage, in which they will brainstorm design solutions through sketches and wireframes. Wireframing is a digital or physical illustration of a user interface, focusing on information architecture, space allocation, and content functionality. Consequently, a wireframe typically does not have any colors or graphics and only focuses on the intended functionalities of the interface. To conclude the Human Centered Design Process, there are two final steps. Upon wireframing or sketching, the designer will usually turn their paper sketches or low fidelity wireframes into high fidelity prototypes. Prototyping allows the designer to explore their design ideas further and focus on the overall design concept. After creating this high fidelity prototype of their design, the designer can then conduct usability testing. This involves collecting participants that represent the target audience of the product and having them walk through the prototype as if they were using the real product. The goal of usability testing is to identify any issues with the design that need to be improved and analyze how real users will interact with the product. To run an effective usability test, it is imperative to take notes on the users behavior and decisions and also have the user thinking out loud while they use the prototype.

As human centered computing has become increasingly popular, many universities have created special programs for HCC research and study for both graduate and undergraduate students.

A user interface designer is an individual who usually with a relevant degree or high level of knowledge, not only on technology, cognitive science, human–computer interaction, learning sciences, but also on psychology and sociology. A user interface designer develops and applies user centered design methodologies and agile development processes that includes consideration for overall usability of interactive software applications, emphasizing interaction design and front end development.

Information architects mainly work to understand user and business needs in order to organize information to best satisfy these needs. Specifically, information architects often act as a key bridge between technical and creative development in a project team. Areas of interest in IA include search schemas, metadata, and taxonomy.

The Human Centered Computing (HCC) group at NASA/Ames Computational Sciences Division is conducting research at Haughton as members of the Haughton Mars Project (HMP) to determine, via an analog study, how we will live and work on Mars. HMP/Carnegie Mellon University (CMU) Field Robotics Experiments—HCC is collaborating with researchers on the HMP/CMU field robotics research program at Haughton to specify opportunities for robots assisting scientists. Researchers in this project have carried out a parallel investigation that documents work during traverses. A simulation module has been built, using a tool that represents people, their tools, and their work environment, that will serve as a partial controller for a robot that assist scientists in the field work in mars. When it comes to take human, computing and environment all into consideration, theory and techniques in HCC field will be the guideline. Ethnography of Human Exploration of Space—HCC lab is carrying out an ethnographic study of scientific field work, covering all aspects of a scientist's life in the field. This study involves observing as participants at Haughton and writing about HCC lab`s experiences. HCC lab then look for patterns in how people organize their time, space, and objects and how they relate to each other to accomplish their goals. In this study, HCC lab is focusing on learning and conceptual change.

Based on the principles of human centered computing, the Center for Cognitive Ubiquitous Computing (CUbiC) at Arizona State University develops assistive, rehabilitative and healthcare applications. Founded by Sethuraman Panchanathan in 2001, CUbiC research spans three main areas of multimedia computing: sensing and processing, recognition and learning, and interaction and delivery. CUbiC places an emphasis on transdisciplinary research and positions individuals at the center of technology design and development. Examples of such technologies include the Note Taker, a device designed to aid students with low vision to follow classroom instruction and take notes, and VibroGlove, which conveys facial expressions via haptic feedback to people with visual impairments. In 2016, researchers at CUbiC introduced "Person Centered Multimedia Computing", a new paradigm adjacent to HCC, which aims to understand a user's needs, preferences, and mannerisms including cognitive abilities and skills to design ego centric technologies. Person centered multimedia computing stresses the multimedia analysis and interaction facets of HCC to create technologies that can adapt to new users despite being designed for an individual.
