Study Notes

Human-Computer Interaction (HCI) Overview

HCI is essential for designing user interfaces for connected devices, ensuring smooth interaction and seamless experiences across platforms.
Originated in the late 1970s within Computer Science, HCI has evolved to address complex societal issues through understanding human behavior.

Historical Context

Prior to the mid-1970s, office work was dominated by paper, typewriters, and bulky computers housed in refrigerated rooms.
The introduction of personal computing is largely credited to innovations by Steve Jobs and Steve Wozniak.

Key Innovations

Xerox Alto (1973):
- Pioneered the idea of a Graphical User Interface (GUI), inspiring future systems despite being commercially unviable.
Macintosh:
- Introduced the desktop metaphor in commercial use via Lisa OS, simulating a physical desk to help users understand digital file organization.

Usability Testing

Usability testing aids in identifying user experience issues and areas for improvement.
Remote Testing:
- Facilitates user interaction from various locations, allowing facilitators to collect data via online platforms.
Pilot Testing:
- Conducted with a small user group before the main usability test to identify potential issues with processes or materials.

Interconnection with Computer Science and Engineering

HCI integrates computer science and engineering to create user-friendly technology interfaces.
Hardware Design:
- Computer engineers design input (keyboards, touchscreens) and output (displays, speakers) devices, affecting user interaction.
Software Development:
- HCI principles guide intuitive and responsive software interface design, built on technical foundations provided by computer science.
Network and Connectivity:
- Computer engineering supports the development of networked devices, enhancing collaborative capabilities.

Evolution of Communication

The rise of the Internet in the 1990s shifted HCI focus towards social interactions facilitated by technology.
Email emerged as a key communication tool, transforming computer usage from solitary tasks to social connectivity.

The diversification of computing devices in the 21st century raised questions about technology's role in everyday life, highlighting a paradox of being connected yet feeling alone.
Ubiquitous computing means technology is deeply integrated into daily tasks, such as exams, appointments, and financial transactions.

Human Input in HCI

Cognitive psychology studies the processes by which humans perceive and interpret information, crucial for effective interface design that aligns with cognitive capabilities and limitations.

Visual Channel in Learning

The visual channel conveys information through sight, emphasizing human sensitivity to light, colors, and focus as key elements in learning and interface design.
