CIS 106 Assignment 4 The Human-Computer Interface(USE AS GUIDE ONLY)
The Human-Computer Interface
Human-Computer Interaction (HCI) is the study and design of how humans use
computers. HCI uses productivity, safety and entertainment to support and fulfill human-
computer interactions and is applied to various types of computer systems, including air traffic
control, nuclear processing, offices and computer gaming (wisegeek).
Haptics, is the technology of adding the sensation of touch and feeling to computers. A
haptic device gives people a sense of touch with computer-generated environments, so that when
virtual objects are touched, they seem real and tangible. Haptic technology has been described
as doing for the sense of touch what computer graphics does for vision. Haptic technology has
made it possible to investigate how the human sense of touch works by allowing the creation of
carefully controlled haptic virtual objects (2012). These objects are used to systematically probe
human haptic capabilities, which would otherwise be difficult to achieve. This type of research
contribute’s to the understanding of how touch and its underlying brain functions work (2012).
Two important applications for haptics are virtual reality and remote operation.
Simplifying the task of integrating haptics into the interface is one factor that would boost the
use of this technology in industrial settings (2012).
Humans have sensory storage, short-term memory, and long-term memory. Sensory
storage works as a buffer to store all the sensory information coming in. Sensory storage can
absorb a huge amount of information, it cannot hold it for a long time because there is always
