Gesture Recognition Sensors and Touchless Sensing – All You Didn’t Know?

Gesture Recognition and Touchless Sensing are giving way to a new trend of interactive services like motion sensor-based games, commands and the list goes on.

Gesture Recognition and Touchless SensingResponding to an external stimulus and converting it to data to work accordingly basically sums up the working of a sensor.

Living in this hi-tech world of smartphones and now accelerating towards Smart Cities, no one can deny the extreme relevance of sensors and their impact on our daily lifestyle.

With numerous developments and researches going on in the technology all around us, it is not a surprise that the line between science fiction and reality is getting thinner as we speak.

How would you feel if by just waving our hands in the air, you could make things happen at any time like our Marvel genius hero Iron Man?

It’s just like your personal AI friend Javier who will serve you all the time.

Getting excited? Well, you should be, as we are going to delve into an interesting talk of the town technology that is Gesture Recognition.

More specifically, Gesture Recognition and Touchless Sensing are giving way to a new trend of interactive services like motion sensor-based games, commands and the list goes on.

However, knowing the basics is always the best first step, so let’s get right into the Gesture Recognition and Touchless Sensing and why they are making new waves in the sensor world.

Decrypting Gesture Recognition and Touchless Sensing

Gesture RecognitionBefore explaining Gesture Recognition and Touchless Sensing, we must understand a little bit about gestures and how they play a relevant role in these sensors.

Gestures represent a natural and intuitive part of our human communication as we express our thoughts and actions without speaking.

Since using gestures to communicate with digital devices in our environment needs very little additional intellectual processing, we can do it without much thinking.

Let’s understand this with the help of an example while driving interacting with a touch screen display needs its drivers to take their eyes off the road to make precise on-screen selections, however, in contrast, gesturing takes minimal attention away from other activities.

And this is just one of the examples, we can cite numerous use cases of the Gesture Recognition Sensors to reveal their impact to emphasize their applications in the real world.

Gesture Recognition Sensors in simpler words can be defined as a technology that leverages sensors to read and interpret hand movements as commands.

Dynamics of Gesture Recognition and Touchless Sensing

Gesture Recognition SensingSince the technology got its roots first in the automobile sector, let’s discuss the working of Gesture Recognition and Touchless Sensing in terms of in-cabin experiences.

Since gesture recognition system requires an HD camera pointed at a specific three-dimensional zone within the vehicle, that could capture frame-by-frame images of hand positions and motions to take the input for its working.

These types of systems are generally used along with infrared LEDs or lasers to take a clear image even when there is not much natural light.

Once input is gained, the images are analyzed in real-time by computer vision and machine learning technologies, that further translate the hand motions into commands, based on either a predetermined library of signs or some customizable instructions saved by the user beforehand.

Though we only talked about the technology being used in automotive, we will now discuss various use cases of Gesture Recognition and Touchless Sensing along with some companies’ initiatives taken to refine this technology.

Gesture Recognition and Touchless Sensing Applications and Market

Gesture Touchless SensingAccording to a recent report on Gesture Recognition and Touchless Sensing, the global gesture recognition technology market had reached 9.7 billion in 2020 and has been predicted to grow at a CAGR of 26.2% during 2021-2026.

Sensing the current trend of successful hand-gesture recognition systems numerous sectors took on the mantle to integrate the technology into gaming as well as in medicine.

Microsoft had recently collaborated with Novartis to develop an innovative system for assessing progressive functioning in patients with multiple sclerosis.

In another application, Google was a step ahead as they declared the Project Soli in 2015 and now have developed Soli Chip that got integrated into Google Pixel 4 smartphone becoming the first device to incorporate the Soli chip.

Soli Chip allows new features for gesture controls like users can now wave their hands to skip songs, snooze alarms and silence phone calls.

Though the chip embedded with the sensor is still not launched in many countries including India due to spectrum issues, Gesture Recognition and Touchless Sensing has made its presence known in a new field.
