Performance Considerations for General-Purpose Typing BCIs, Including the Handwriting BCI. Technical Report #01.
Abstract/Contents
- Abstract
- This is an informal technical report regarding performance considerations for general-purpose typing brain-computer interfaces (BCIs). A general-purpose typing BCI is a BCI that enables the user to type any string of characters (as opposed to a BCI that can only type certain strings, such as sequences of words drawn from a small set of allowed words). This living document is intended to grow, evolve and serve as a resource for the community. We use our new Handwriting BCI [1] as an example system. In addition to this technical report (Technical Report #01), we are also openly sharing all electrophysiology data (Dryad, [2]) and all code (Python, GitHub, [3]) from the paper [1]. Defining and measuring performance metrics are key to our community’s ability to compare, coordinate and cooperate in order to advance general-purpose typing BCIs and bring them into widespread clinical use. This report begins with investigations in people with paralysis (Sections 1-5), where our studies are part of the BrainGate2 pilot clinical trial (NCT00912041)1 with Prof. Leigh Hochberg (sponsor-investigator), Prof. Jaimie Henderson (NPTL co-director, BrainGate2 Stanford site PI), Prof. Krishna Shenoy (NPTL co-director), Dr. Frank Willett (Research Scientist) and Prof. Paul Nuyujukian (NPTL alumnus). This report also includes pre-clinical studies with nonhuman primates (NHPs, rhesus macaques; Section 6), where our studies are part of NPSL with Prof. Krishna Shenoy (Director) and Prof. Paul Nuyujukian (NPSL alumnus). This living document is intended to be inclusive, accurate and accessible to students and investigators. We welcome suggested corrections, edits and additions; please contact Krishna Shenoy (shenoy@stanford.edu).
