HAND DETECTION DEVICE, GESTURE RECOGNITION DEVICE, AND HAND DETECTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18036344 titled 'HAND DETECTION DEVICE, GESTURE RECOGNITION DEVICE, AND HAND DETECTION METHOD
Simplified Explanation
The patent application describes a hand detection device used in vehicles. Here is a simplified explanation of the abstract:
- The hand detection device captures an image of a specific region in a vehicle to detect hands.
- It calculates the difference in brightness between consecutive frames of the captured image.
- Using this information, it detects the presence of a user's hand in the image.
- It also determines if the detected hand is a false positive by comparing the brightness difference between the frame with the detected hand and the previous frame in the hand detection area.
Potential Applications:
- Automotive industry: This technology can be used in vehicles to detect the presence of a driver's hand on the steering wheel or other control surfaces.
- Human-computer interaction: It can be applied in various human-computer interaction systems, such as touchless gesture control or virtual reality, to detect and track hand movements.
Problems Solved:
- Accurate hand detection: The device improves the accuracy of hand detection by considering the luminance difference between frames, reducing false positives.
- Error reduction: By determining if a detected hand is a false positive, it helps prevent erroneous actions or commands based on incorrect hand detection.
Benefits:
- Enhanced safety: In vehicles, accurate hand detection can contribute to safer driving by ensuring that the driver's hands are on the controls when necessary.
- Improved user experience: In human-computer interaction systems, reliable hand detection enables more intuitive and seamless interactions, enhancing the user experience.
Original Abstract Submitted
In the hand detection device, an image acquisition unit acquires an image for hand detection, which is an image obtained by capturing a hand detection region in a vehicle. A luminance difference calculation unit calculates an inter-frame luminance difference of the image for hand detection. A hand detection unit detects a hand of a user from the image for hand detection. An erroneous detection determination unit determines whether or not the detected hand has been erroneously detected on the basis of the luminance difference between the frame in which the hand has been detected and the frame immediately preceding thereof in the hand detection area.
