HTAD: a Home Tasks Activities Dataset.
======================================
### [[Preprint]](https://osf.io/j723c/)
___________________
The dataset was collected using a wrist accelerometer and audio recordings. The dataset contains data for common home tasks activities like *sweeping, brushing teeth, watching TV, washing hands*, etc. To protect users' privacy, we only include audio data after feature extraction. For accelerometer data, we include the raw data and the extracted features.
### Dataset structure
* **HTAD dataset**: Main Directory.
* **user1**: A directory containing user1 data.
* **timestamp-acc-label.txt**: Unix format. *acc* stands for accelerometer and *label* is the activity's label. Each **.txt** file has four columns: timestamp and the acceleration for each of the x, y, and z axes.
* ...
* **user2**: A directory containing user2 data.
* **timestamp-acc-label.txt**
* ...
* **user3**: A directory containing user3 data.
* **timestamp-acc-label.txt**
* ...
* **features.csv**: file contains the extracted audio features and accelerometer features. It contains 54 columns. *userid* is the user id. *label* represents the activity label and the remaining columns are the features. Columns with a prefix of *v1_* correspond to audio features whereas columns with a prefix of *v2_* correspond to accelerometer features. In total, there are 36 audio features that correspond to the 12 MFCCs for each second, with a total of 3 seconds and 16 accelerometer features.
* **README.txt**: Readme file.
