WeAllWalk: An Annotated Data Set of Inertial Sensor Time Series from Blind Walkers

We introduce WeAllWalk, a data set of inertial sensor time series collected from blind walkers using a long cane or a guide dog. Blind participants walked through fairly long and complex indoor routes that included obstacles to be avoided and doors to be opened. Inertial data was recorded by two iPhone 6s carried by our participants in their pockets and carefully annotated. Ground truth heel strike times were measured by two small inertial sensor units clipped to the participants' shoes. We also show comparative examples of application of step counting and turn detection algorithms to selected data from WeAllWalk.
