The Raskin Center for Humane Interfaces (RCHI) was founded to carry forward the research and design principles developed by Jef Raskin over his career in human-computer interaction.
History
After Jef Raskin’s passing in 2005, colleagues and family members established the RCHI to preserve his work and continue developing the interface design concepts he championed. The center maintained archives of his published research, developed prototype software demonstrations, and advocated for humane interface design principles in the broader technology community.
Jef Raskin’s Vision
Raskin believed that the fundamental problem with most computer interfaces was that they were designed around the machine’s architecture rather than around human cognition. He identified several key problems:
- Modes cause errors because users lose track of which mode they are in
- File systems force users to organize information the way computers store it, not the way humans think about it
- Inconsistent interfaces prevent the formation of habits, forcing conscious attention on routine tasks
- Unnecessary complexity wastes human cognitive resources
The Humane Interface Principles
The RCHI promoted Raskin’s core principles:
- An interface is humane if it is responsive to human needs and considerate of human frailties
- The primary measure of interface quality is efficiency — how much effort is required to accomplish a task
- Modes should be eliminated wherever possible
- Interfaces should be learnable, consistent, and forgiving of errors
- Design decisions should be based on measured cognitive science, not opinion
