The OnHW Dataset

The OnHWchars Dataset

The task associated with this dataset is to classify characters from the sensor data provided by the STABILO Digipen. This introduces unique problems to be solved by the research field of multivariate time series classification, as every writer has their personal way of writing and their own way of holding the pen. Furthermore, writer-dependent as well as writer-independent evaluations can be performed.

The dataset is described in detail in the paper referenced below.

The dataset can be downloaded here (180 MB).
For information on the content, see the readme.txt file.

The STABILO Challenge for Ubicomp 2020 used a slightly adapted version of this dataset.

Changelog:
2020-09-14: Dataset release
2020-09-22: Improved readme file
