Viewing Beyond Sight: Future Video Technologies That Stimulate Touch and Smell
Video technology has evolved over many years as entertainment that appeals to our vision. Image-centered entertainment such as film, television, and VR, or virtual reality, has focused on sight and sound, but future viewing experiences will go further. New technologies that appeal to senses such as touch and smell are emerging, and the world of moving images is beginning to offer unprecedented immersion.
These technologies let us enjoy viewing experiences using all five senses, with possibilities expanding beyond entertainment into medicine, education, and business. This article focuses on future video technologies that stimulate touch and smell, exploring their feasibility and prospects.
Haptic Feedback: The Evolution of “Touching” Images
One technology attracting attention in experiences that use touch is haptic feedback. It recreates the sensation of touching objects within images and is developing mainly in VR and gaming. Haptic feedback devices convey tactile information from the visual world in real time through devices such as gloves worn on the hands or vibration motors built into chairs and vests.
In a VR game, for example, when a user swings a sword or grasps an object, vibrations or pressure are transmitted to the hands in time with the action, recreating the feeling of actually manipulating something. This technology enables experiences in which users take action themselves within films and games, creating deeper immersion.
Haptic feedback is also used beyond entertainment, in medicine and education. In surgical simulations and science experiments, for example, tactile experiences that feel like using actual tools are expected to improve students’ learning.
Olfactory Simulation: Technology That Enriches Viewing Through Scent
Alongside touch, technology that stimulates smell is attracting attention. Smell is closely linked to emotion and memory, and scent-based experiences are known to have a strong emotional impact. In the world of moving images, efforts are advancing to create immersive experiences combining sight and smell by reproducing scents associated with particular scenes and places.
Olfactory simulation technology is currently developing devices that generate specific scents and deliver them to users. Introduced in cinemas or VR experience venues, for example, this technology can reproduce the smell of damp earth during a rainy scene, or the scent of a campfire and forest during a camping scene. Recreating these scents adds realism to the viewing experience and strongly appeals to audiences’ emotions and memories.
Olfactory technology is also beginning to find commercial applications. Reproducing a product-related scent in a video advertisement, for example, is expected to make a deeper impression in viewers’ memories and strengthen their perception of the product. The power of smell is becoming an important element that does more than complement sight and sound: it evokes emotion and enriches the viewing experience.
The Future of Viewing with All Five Senses
As haptic and olfactory technologies evolve, future viewing experiences are developing into comprehensive entertainment that uses all five senses, beyond sight and sound. Their combination with VR, in particular, is expected to increase immersion in films and games, as well as in education and medicine.
In future cinemas, for example, touch and smell may be stimulated in real time according to each scene, allowing audiences to feel as though they are inside the film. They may feel vibrations and heat during an explosion in a war film, or smell flowers during a romantic scene, receiving deeply emotional experiences through all five senses.
These technologies may also be used in medicine and rehabilitation. Rehabilitation using haptic feedback provides an environment in which patients can control their bodies and experience their recovery process. Certain scents have also been shown to reduce stress and anxiety, suggesting that olfactory technology may find wider applications in mental health care.
Challenges and Future Possibilities
Many technical challenges remain for haptic and olfactory technologies. Olfactory simulation, in particular, requires technologies that accurately reproduce scents and control them so they disappear instantly. Haptic feedback also faces issues with device size and cost, so widespread adoption may take a little longer.
Nevertheless, these technologies may continue evolving to offer new viewing experiences that do not rely solely on sight and sound. In entertainment especially, integrating touch and smell will likely produce a new dimension of visual work that offers sensory immersion as well as visual beauty.
Conclusion
Viewing beyond sight holds great potential for the future through the evolution of new technologies that stimulate touch and smell. By expanding beyond entertainment into education, medicine, and commerce, these technologies will bring new value to our lives. Future viewing experiences are expected to open a new world of deeper emotional connections, engaging all five senses rather than only sight and sound.
