ZJU-GaitAcc is the first publicly available dataset of gait acceleration series. It contains the gait acceleration series of 175 subjects. 153 of them are present in 2 sessions (Session 1 & 2), and 22 of them are in only 1 session (Session 0). For each subject, 6 records are included in one session, where every record contains 5 gait acceleration series simutalneously measured at the the right wrist, left upper arm, right side of pelvis, left thigh, and right ankle, respectively.
The detailed specification of this dataset can be found in the citation, where an evaluation protocol for identification and verification is also provided.
According to our agreements with the volunteers, we should not record or release any specific personal information other than the gait acceleration. We can provide only some rough statistics of the datasets:
• About 2/3 are male, 1/3 are female
• Age: 16 ~ 40
• Height: 1.5 ~ 1.9 m
Option 1: The database is publically available for non-commercial use. To obtain a copy of the database, please download the ZJUGaitAcc Database release agreement, sign it after carefully reading, and send a scan to Gang Pan (gangpan AT gmail.com). We will soon reply to you.
Option 2: Alternatively, you can signing an ONLINE agreement. You will be informed with the download URL immediately after completion.

We provide a development tookit to faciliate the usage (such as data reading) of the dataset. Click here for more information.
To make the dataset readable without any specific (commercial) software, we stored the data in text files, which are organized in a directory tree.
