| The dataset consists of videos showcasing individuals demonstrating 5 different | |
| hand gestures (*"one", "four", "small", "fist", and "me"*). Each video captures | |
| a person prominently displaying a single hand gesture, allowing for accurate | |
| identification and differentiation of the gestures. | |
| The dataset offers a diverse range of individuals performing the gestures, | |
| enabling the exploration of variations in hand shapes, sizes, and movements | |
| across different individuals. | |
| The videos in the dataset are recorded in reasonable lighting conditions and | |
| with adequate resolution, to ensure that the hand gestures can be easily | |
| observed and studied. | |
