PRECIS HAR represents a RGB-D dataset for human activity recognition, captured with the 3D camera Orbbec Astra Pro. It consists of 16 different activities (stand up, sit down, sit still, read, write, cheer up, walk, throw paper, drink from a bottle, drink from a mug, move hands in front of the body, move hands close to the body, raise one hand up, raise one leg up, fall from bed, and faint), performed by 50 subjects.


The dataset consists of RGB data (.mp4 files) and depth data (.oni files). We provide both cropped and raw versions. The cropped videos are shorter, containing only the seconds of interest, i.e. where the activity is performed. The raw videos are longer, containing all the video that we captured while filming the dataset. We included both variants, because they can all be useful for different applications.

Video names follow the pattern <subject_id>_<activity_id>.<extension>, where:

  • <subject_id> is an integer between 1 and 50;

  • <activity_id> is an integer between 1 and 16, with the following mapping: 1 = stand up, 2 = sit down, 3 = sit still, 4 = read, 5 = write, 6 = cheer up, 7 = walk, 8 = throw paper, 9 = drink from a bottle, 10 = drink from a mug, 11 = move hands in front of the body, 12 = move hands close to the body, 13 = raise one hand up, 14 = raise one leg up, 15 = fall from bed, 16 = faint;

  • <extension> is .mp4 or .oni, depending on the type of data (RGB or depth).

 In order to manipulate .oni files, we recommend using pyoni.
