Here’s what I found to be a good overview:
Gesture recognition is a touchless technology that allows devices to understand and respond to human movements as commands. Gesture recognition works by using cameras and sensors to pick up movements from parts of the body like hands or the face. These movements are turned into digital data that...

Some excerpts:
What is Gesture Recognition?
Gesture recognition refers to the technology that interprets human gestures, such as hand movements, facial expressions, or body language, through mathematical algorithms. It enables humans to interact with machines and computers without using mechanical devices like keyboards, mice, or touchscreens. Gesture recognition works by using cameras and sensors to pick up movements from parts of the body like hands or the face. These movements are turned into digital data that computers can understand.

Gesture Recognition and Detection Technologies
- Sensor-Based Hand Gesture Recognition: A sensor-based gesture recognition program detects and analyses human gestures. This can be accomplished using a variety of sensors, including cameras, infrared sensors, and accelerometers. These sensors gather information about the movement and location of a person's body or limbs, which the algorithm subsequently utilizes to recognize specific motions.
- Vision-Based Hand Gesture Recognition: A vision-based gesture recognition system detects and interprets motions using cameras or other visual sensors. The cameras collect photos or videos of the user's gestures, which are then analyzed and identified using computer vision and machine learning techniques.
Gesture Recognition Examples and Uses
- Smart TVs: Modern smart TVs use gesture recognition, allowing viewers to switch channels, adjust the volume, or browse through menus with simple hand movements. This means you don’t always need to use a remote control, making it more convenient and accessible.
- Home Automation Systems: In smart homes, gesture recognition enhances user interaction by enabling control over the home environment. For instance, waving your hand can turn lights on or off, adjust the thermostat, or manage your home entertainment systems, integrating seamlessly with smart home technology for improved convenience and energy efficiency.
- Gaming Consoles: Devices like the Microsoft Kinect have transformed gaming, providing a motion-controlled gaming experience where players use their body movements to interact with the game. This adds a level of physical activity and immersion to gaming, making it more engaging and interactive.
- Automotive: Modern cars incorporate gesture recognition for safer and more convenient control of various features. Drivers can execute commands like adjusting the stereo volume, changing air conditioning settings, or answering phone calls with simple hand gestures, minimizing distractions and enhancing focus on driving.
- Virtual Reality (VR) and Augmented Reality (AR): These technologies heavily rely on gesture recognition for user interaction. In VR and AR environments, users can manipulate objects, navigate menus, or control applications through gestures, creating a more immersive and interactive experience without needing physical controllers.
- Kitchen Appliances: Advanced kitchen gadgets are adopting gesture recognition, allowing for hands-free operation. For example, with a wave of your hand, you can operate microwaves, ovens, or smart faucets, adding convenience and hygiene to cooking and kitchen management.

Conclusion
Gesture recognition is a technology that allows devices to understand and respond to human movements. Using advanced machine learning algorithms like CNNs and SVMs, it transforms physical gestures into digital commands, making interaction with gadgets more intuitive and seamless. This technology enhances user experience in smart homes, gaming, automotive, and virtual reality, among other areas. As we move towards more
interactive and
user-friendly technologies, gesture recognition stands out as a key player in bridging the gap between humans and machines, making our interactions more natural and efficient.
Apart from the use cases listed above, human-robot interaction comes to mind - think of the proof-of-concept the researchers from Fraunhofer HHI’s Wireless Communications and Networks Department demonstrated with the help of Spot, the robot dog, as part of 6G-RIC (Research and Innovation Cluster),
funded by Germany’s Federal Ministry of Education and Research:

Human-robot interaction via gesture recognition is also of particular interest in the healthcare sector. Halfway through this August 2024 post
https://thestockexchange.com.au/threads/brn-discussion-ongoing.1/post-433491, I summarised a fascinating podcast I had listened to.
Here are some excerpts:
“I chanced upon an intriguing German-language podcast (Feb 1, 2024) titled “6G und die Arbeit des 6G-RIC” (“6G and the work of the 6G-RIC”) with Slawomir Stanczak as guest, who is Professor for Network Information Theory at TU Berlin, Head of Fraunhofer HHI’s Wireless Communications and Networks Department as well as Coordinator of the 6G Research and Innovation Cluster (6G-RIC):

From 17:12 min onwards, the podcast host picks up the topic of connected robotics and mentions a collaboration with Charité Universitätsmedizin Berlin, which is Germany’s biggest (and very renowned) university hospital, regarding the development of nursing robots and their control via 6G.
Stanczak confirms this and shares with his listeners they are in talks with Charité doctors in order to simplify certain in-hospital-processes and especially to reduce the workload on staff. Two new technological 6G features are currently being discussed: 1. collaborative robots and 2. integrated communication and sensing (ICAS).
Stanczak and his colleagues were told that apart from the global nursing shortage we are already facing, it is also predicted that we will suffer a shortage of medical doctors in the years to come, so the researchers were wondering whether robots could possibly compensate for this loss.
The idea is to connect numerous nursing robots in order to coordinate them and also for them to communicate with each other and cooperate efficiently on certain tasks - e.g., comparatively simple ones such as transporting patients to the operating theatre or serving them something to drink [of a non-alcoholic nature, I presume

]. But the researchers even envision complex tasks such as several robots collaborating on turning patients in bed.
Telemedicine will also become more important in the future, such as surgeons operating remotely with the help of an operating robot [you may have heard about the da Vinci Surgical System manufactured by Intuitive Surgical], while being in a totally different location.
[Something Stanczak didn’t specifically mention, but came to my mind when thinking of robot-control via gesture recognition in a hospital setting, is the fact that it would be contactless and thus perfect in an operating theatre, where sterile conditions must be maintained.] (…)”
Think of a surgeon using hand gestures during an operation to instruct a medical assistant robot to pass him/her the correct surgical instruments.
Then there is the whole field of industrial robots.
Fortiss, for example, has an ongoing project in collaboration with NEURA Robotics and TU Chemnitz called CORINNE (Cobots’ Relational Interface with Neuromorphic Networks and Events) that “aims to build robots that can recognise and respond to gestures (known or unknown), to interact with humans on welding tasks”. They are using Loihi for that project running from April 2024 to March 2026, in case you wondered.

So while gesture recognition and neuromorphic technology undoubtedly make a fruitful liaison, we as BRN shareholders won’t get to taste the sweetness of that ripe fruit until customers actually start signing on the dotted line.
