• WeAllWalk: An Annotated Dataset of Inertial Sensor Time Series from Blind Walkers

  Germán H. Flores, Roberto Manduchi (2018) — ACM Transactions on Accessible Computing (TACCESS)

  This paper introduces WeAllWalk, an annotated dataset of inertial sensor time series collected from blind and sighted walkers navigating complex indoor routes. Ten blind volunteers (seven using a long cane, one using a guide dog, and two alternating …
