Personal dynamic media
The Xerox PARC Learning Research Group—especially the work associated with Alan Kay, Dan Ingalls, Adele Goldberg, and their colleagues—demonstrated a live, graphical, reflective, object-oriented environment conceived as a medium for thought. System-128 inherits the ambition, not the name or institutional lineage.
Interaction as complete design
Apple’s early Macintosh work, later human-interface traditions, and research associated with people such as Don Norman sharpened lessons about coherence, feedback, discoverability, mental models, accessibility, consistency, and emotional experience. Power alone does not make an environment usable.
Systems & composition
Unix and Bell Labs traditions contribute small parts, clear contracts, orthogonality, composition, and separation of mechanism from policy. Plan 9, distributed systems, persistent object research, Self, and other live environments extend the conversation about naming, location, prototypes, and scale.
Specification & intent
Design by Contract, requirements engineering such as KAOS and i*, architectural modeling, formal specification, ontology languages, capability systems, and software verification supply vocabulary and techniques for obligations, goals, authority, and evidence.
