# BCI Human Interface Device **Type:** Interface protocol **Collection:** [[collections/Neurotech|Neurotech]] **Primary source:** [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] ## Definition BCI-HID is the Apple device-input protocol described as making brain-computer interfaces a native accessibility input category. ## Relationships [[wiki/BCI Human Interface Device|BCI-HID]] is related to [[wiki/Synchron|Synchron]], [[wiki/Apple|Apple]], [[wiki/Stentrode|Stentrode]], and operating-system accessibility. ## Source route [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] · [[collections/Neurotech|Neurotech]] ## Neurotech source route **Collection:** [[collections/Neurotech|Neurotech]] **Source article:** [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]]  ### Master relationship graph patch — 2026-09-10 **Collection:** [[collections/Neurotech|Neurotech]] **Relationship source:** [[research/Neurotechnology Ecosystem Relationship Graph - 2026-09-10|Neurotechnology Ecosystem Relationship Graph — 2026-09-10]] **Related source articles:** [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] · [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report on Brain-Computer Interfaces]] · [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] #### Incoming typed edges - **Edge 413 — [[wiki/BCI Operating-System Substrate|operating-system BCI integration]] `bridge_entities` → this entry** — **CORPUS**; evidence `CORPUS_BCI`, `CORPUS_ATLAS`. Treat OS/API layer as its own wiki entry, not a Synchron footnote. #### Epistemic boundary `VERIFIED`, `VERIFIED_SECONDARY`, `CORPUS`, `STRONG_TECHNICAL_LINEAGE`, `STRONG_TECHNICAL_CONVERGENCE`, `ANALYTIC`, and `UNRESOLVED` are retained as distinct relation states. An edge does not imply ownership, control, funding, licensing, technology transfer, or organizational identity unless its predicate and evidence state that relationship explicitly.
