‘Haptic technology and digital will merge with reality


While the digital world has mainly consisted of visual and auditory perception until now, touch technology, also known as “haptic technology”, is expected to increase products that provide tactile feedback in the coming years.

Emphasizing that the perceived information has many advantages, scientists state that the information will reach people quickly and directly, opening up a sense dimension that has not been used before.

Expressing that haptic feedback will once again support what the person sees or hears, experts note that this will bring the digital and real world closer together.

Technology giants continue their tactile feedback studies

Apple, one of the technology giants of the US, filed an “interesting” patent application in the past weeks. Apple wants to install “actuators” in Airpod headsets and other portable devices that convert electrical signals and electricity into mechanical motion or light.

While imagination knows no bounds in technology, Google and Chinese Xiaomi are also working to improve tactile feedback and provide more physical responsiveness.

As cars become more digital, automotive manufacturers and suppliers are increasingly interested in haptic feedback.

Can be used in many areas from defense industry to medicine

It is stated that “haptic technology” can be used in many areas from defense industry to medicine, from education to daily life. It is noted that the integration of haptic feedback with touch screens will lead to new applications in user interface design, online shopping, gaming and entertainment, education, arts and many more.

While companies expect haptic feedback to make a significant difference in sales first, they say a number of products will be on the market within 2 to 3 years.

Stating that the human brain responds to the sense of touch much faster than the eyes, experts emphasize that the receptors notice temperature differences, pressure, yawning and vibration, and transmit information to the brain within milliseconds. Noting that the sense of touch cannot be closed, experts state that this technology can be felt even if the eyes are closed.

“You will be able to feel the surface roughness of a sweater you will buy from the internet on your phone”

Koç University Faculty Member Prof. Dr. Çağatay Başdoğan gave information about “haptic technology” and the work done in this field, in a statement he made to the state-run Anadolu Agency.

Stating that “haptic” means “sense of touch”, Başdoğan explained that it is divided into two groups as “kinesthetic” and “tactile”. Başdoğan continued as follows:

“For example, if your car tire has punctured and you are pushing behind it, this tactile interaction is force-based and is in the ‘kinesthetic’ group. If you are trying to understand the texture of a fabric with your finger, this interaction is more sensitive and sensation occurs through the receptors on the fingertips and falls into the ‘tactile’ group. aims to provide both kinesthetic and tactile tactile feedback to the user. “

Referring to the usage areas of “haptic technology”, Başdoğan said, “Especially in recent years, studies on transmitting tactile tactile feedback to the user through mobile devices have increased. We call this field” surface tactile “. Thanks to the methods developed in these studies, tactile feedback can be provided to the user through vibration and friction. For example, you will be able to feel the surface roughness of a sweater you buy over the internet on your phone screen. ” said.

The number of studies on tactile systems is also on the rise in Turkey.

Prof. Dr. Çağatay Başdoğan pointed out that the number of studies in the field of surface touch has increased worldwide, “Mobile device and automobile manufacturers are also interested in this issue. I believe that the mentioned technologies will enter mobile devices and automobiles in the next 10 years.” found the assessment.

Pointing out that the number of studies on tactile systems has increased in Turkey, Başdoğan stated that the studies conducted by Koç University Robotics and Mechatronics Laboratory, which are especially research groups, in this field are known in the world literature.

Başdoğan said, “Our group works on how people touch and perceive, how to bring this feeling to machines, and the tactile interactions between human and machine.” said.

“This technology can be used to consolidate information for security purposes”

Waterloo University System Design Engineering Faculty Member Assoc. Dr. John Zelek said that “haptic technology” is “technology that creates an artificial sense of touch that can be felt through the sense of touch”.

“We live in a visual world and we rely mainly on our eyes. This technology can be used to reinforce information for safety purposes, for example in a factory with visual or auditory alerts or while driving. This can be a vibration in the seat or a sensation in the steering wheel,” Zelek said. It is also useful for visually impaired people to help them see using a sensory sense they still have. ” he spoke.

Citing vibration in smartphones as an example of “haptic technology”, Zelek said the problem with this technology is that most of the underlying devices are vibration motors and it’s primitive.

“If we can develop a device that simulates someone touching us or squeezing us, we’ll provide a richer sense of information and make better use of our tactile modality,” Zelek said. said.
