MCD-Gesture Dataset: mmWave Cross Domain Gesture Dataset

News

• We have released the code of DI-Gesture.

• We have released various human sensing datasets based on wireless signals, including WiFi localization and mmWave imaging.

• This dataset has been downloaded by researchers from over 60 institutions worldwide.

• We have released the raw ADC data to support custom signal processing techniques.

Overview

This is the dataset for paper "Towards Domain-Independent and Real-Time Gesture Recognition Using mmWave Signal, IEEE TMC 2022". It is an open-source mmWave gesture dataset collected from various domains (i.e. environments, users, and locations), and it can be used to develop mmWave gesture recognition systems and domain-independent machine learning algorithms. Following we introduce the composition and implementation details of this dataset.

Dataset Introduction

• 750 domains: 6 environments x 25 volunteers x 5 locations
• 6 environments：meeting room, living room, bedroom, laboratory, and 2 office rooms
• 25 volunteers：25 users with different sex, ages, heights, and weights.
• 5 locations：5 anchor locations with different distances and angles away from the radar, ranging from 0.6m to 1m and -30° ,to 30°.
• 13 gestures: 6 predefined gestures (push, pull, slide left, slide right, clockwise turning, counterclockwise turning) and 7 other actions as negative samples (lifting right arm, lifting left arm, sitting down, standing up, waving hand, turn around, walking).
• 24050 samples: 10650 gesture samples + 13400 negative samples, with 695193 radar frames in total.

Dataset Implementation

Hardware Configuration

• This dataset is collected by TI AWR1843 mmWave radar (left) and DCA1000 real-time data acquisition board (right).

• The parameters of the radar are set as follows:

Parameter	Value	Parameter	Value
Start frequency	77GHz	Sample points	128
Frequency slope	99.987MHz/µs	Sample rate	4MHz
Idle time	340µs	Chirps in one frame	128
Ramp end time	40µs	Frame periodicity	50ms

Under these settings the radar achieves a frame rate of 20fps, a range resolution of 0.047m, a velocity resolution of 0.039m/s. The number of activated transmitting antennas and receiving antennas are 2 and 4, respectively.

Data preprocessing

The raw signals are processed into Dynamic Range Agnle Image (DRAI) sequences through 3D-FFT and noise elimination. DRAI depicts doppler power distribution over spatial positions when people perform gestures. For example, the following figure shows a series of DRAI when user perform gesture "push". In DRAI, the pixel intensity corresponds to doppler power, the horizontal axis is angle of arrival and the vertical axis is range. It can be observed that when users perform push, the brightest spot moves vertically which denotes distance changes of hands.

Dataset Structure

• The DRAI sequence of each gesture sample is saved as numpy array with 3 dimensions T x 32 x 32, where the first dimension represents the frame length of the DRAI sequence, and the last two dimensions represent the size of one frame DRAI. The format of each .npy filename is y/n_GestureName_EnvironmentLabel_UserLabel_PositionLabel_SampleLabel.npy and the first character represents whether it is a predefined gesture (y) or negative sample (n). For example, the filename "y_SlideRight_e6_u21_p5_s4" denotes that it is the 4th sample of predefined gesture "SlideRight" performed by user21 at location5 in environment6.

• The example video of how to perform the predefined gestures can be viewed here.

• The number of samples collected from each volunteer is as follows:

User	Sample
User A-User G (7)	7 Users x 5 Rooms x 5 Locations x (6 Gestures x 5 Instances + 60 Negative samples) = 12250 Samples
User H-User I (2)	2 Users x 4 Rooms x 5 Locations x (6 Gestures x 5 Instances + 60 Negative samples) = 2800 Samples
User J-User L (3)	3 Users x 3 Rooms x 5 Locations x (6 Gestures x 5 Instances + 60 Negative samples) = 3150 Samples
User M-User N (2)	2 Users x 2 Rooms x 5 Locations x (6 Gestures x 5 Instances + 60 Negative samples) = 1400 Samples
User O-User R (4)	4 Users x 1 Room x 5 Locations x (6 Gestures x 10 Instances + 60 Negative samples) = 2000 Samples
User S-User Y (7)	7 Users x 1 Room x 5 Locations x (6 Gestures x 5 Instances + 60 Negative samples) = 2450 Samples
