Goals for computers




Human–computer interaction studies the ways in which humans make—or do not make—use of computational artifacts, systems and infrastructures. Much of the research in the field seeks to improve human–computer interaction by improving the usability of computer interfaces. How usability is to be precisely understood, how it relates to other social and cultural values and when it is, and when it may not be a desirable property of computer interfaces is increasingly debated.

Much of the research in the field of human–computer interaction takes an interest in:

  • Methods for designing new computer interfaces, thereby optimizing a design for a desired property such as learnability, findability, efficiency of use.
  • Methods for implementing interfaces, e.g., by means of software libraries.
  • Methods for evaluating and comparing interfaces with respect to their usability and other desirable properties.
  • Methods for studying human-computer use and its sociocultural implications more broadly.
  • Methods for determining whether or not the user is human or computer.
  • Models and theories of human computer use as well as conceptual frameworks for the design of computer interfaces, such as cognitivist user models, Activity Theory or ethnomethodological accounts of human computer use.
  • Perspectives that critically reflect upon the values that underlie computational design, computer use and HCI research practice.

Visions of what researchers in the field seek to achieve vary. When pursuing a cognitivist perspective, researchers of HCI may seek to align computer interfaces with the mental model that humans have of their activities. When pursuing a post-cognitivist perspective, researchers of HCI may seek to align computer interfaces with existing social practices or existing sociocultural values.

Researchers in HCI are interested in developing design methodologies, experimenting with devices, prototyping software and hardware systems, exploring interaction paradigms, and developing models and theories of interaction.

Principles edit The following experimental design principles are considered, when evaluating a current user interface, or designing a new user interface: Early focus is placed on user(s) and task(s): How many users are needed to perform the task(s) is established and who the appropriate users should be is determined (someone who has never used the interface, and will not use the interface in the future, is most likely not a valid user). In addition, the task(s) the users will be performing and how often the task(s) need to be performed is defined. Empirical measurement: the interface is tested with real users who come in contact with the interface on a daily basis. The results can vary with the performance level of the user and the typical human–computer interaction may not always be represented. Quantitative usability specifics, such as the number of users performing the task(s), the time to complete the task(s), and the number of errors made during the task(s) are determined. Itera...

22) Republic Day 2020 Parade FEATURES: Colourful tableaux, daredevilry, government might on display

India Republic Day -- The indian subcontinent Republic Day 2020 Ornement, Flag Hosting HIGHLIGHTS: Excellent Minister Narendra Modi paid his tributes to martyrs by laying a wreath at the National War Memorial in the presence of Support Minister Rajnath Singh, the 3 service chiefs and Primary of Defence Staff Bipin Rawat. India Republic Morning Parade 2020, Flag Hosting HIGHLIGHTS: India is drinking its 70th Republic Morning Today. The celebration in Rajpath started with Excellent Minister Narendra Modi having to pay homage to the fallen military at the newly-built National Warfare Memorial on the Republic Morning for the first time instead of the Amar Jawan Jyoti beneath the India Gate arch. This was followed by Leader Ram Nath Kovind unfurling the tricolour. The special occasion marks the day when India’s Constitution came into effect, plus the country became a republic. Heavylift helicopter Chinook and also attack helicopter Apache, each recently inducted in the Indian Air Force,...
