Lightning strikes, lasting less than a half-millionth of a second, often scorch the skin but don't cause internal burns. Just as crucial, most of the electricity in a lightning bolt does not pass through the body. Rather, it dissipates over the skin in what's known as a flashover. Vernon Cooray, a lightning scientist at Uppsala University in Sweden, explains the phenomenon by contrasting the ways a human body and a tree react when struck.
Human-computer interaction (HCI) is the study and planned design of human and computer activities. HCI uses productivity, safety and entertainment to support and fulfill human-computer activities and is applied to various types of computer systems, including air traffic control, nuclear processing, offices and computer gaming.
The Human-Computer Interaction (HCI) degree option is part of the Bachelor of Science in Human Centered Design & Engineering (BSHCDE) degree program.All students interested in pursuing the HCI degree option within the BSHCDE should contact their academic adviser.tudents interested in HCI can complete the official HCI option with coursework from four participating departments: Human Centered Design & Engineering, Computer Science & Engineering, the Division of Design within the School of Art, and The Information School.
