What Is Haptic Feedback? The Complete Guide
Updated: December 22,2022
Even though this technology has been around since the 70s, and was widely implemented in gaming with the first DualShock PlayStation controller in 1997, most people still can’t answer the question: “What is haptic feedback?” However, even if not everyone is aware of what it is, haptic feedback is now practically everywhere in gaming – and not only there!
In fact, haptic technology has revolutionized how we interact with our digital environment and brought a new level of interaction to all user interfaces.
Our in-depth guide will cover exactly what haptic feedback is, from how it works, to its applications in gaming and beyond. Whether you're trying to gain an edge over your gaming opponents or just want a better understanding of modern gadgets - keep reading to learn all about haptic feedback!
What Is Haptics?
Haptics allows users to interact with digital devices using tactile feedback. Haptics creates the sensation of tactile feedback through vibrations, force, and motion.
Augmented reality (AR) games incorporate this technology, but it has plenty of other use cases, e.g., teaching and conducting medical procedures, creating interactive user interfaces for phones and tablets, or even simulating physical environments for flight simulators. The potential applications are vast and have driven the increased production of haptic devices.
In short, this tech relies on sensors and actuators that detect user input and generate forces accordingly. These actuators are often small motors that generate vibrations or resistive forces the user can feel.
Thanks to these haptic components, users can interact with virtual objects and environments in a way that mimics real-world sensations. For example, haptics can provide feedback to medical professionals when they're using devices such as endoscopes or simulate the feeling of touching a wall or surface when playing an AR game. This has made such games popular enough for the expected revenue of AR video gaming to reach $11.6 billion by 2025.
How Does Haptic Feedback Technology Work?
As mentioned, haptic actuators are embedded into a device's casing and produce vibrations that can range from subtle to strong force feedback, depending on the user’s preference. These elements will vibrate when certain actions or events occur within the game or application, such as opening a door or switching between menus.
The haptics can also be programmed to adjust their intensity levels based on changes within the game environment – for instance, if the volume of an explosion goes up, the haptic vibration can become more intense. This helps create a physical connection to the virtual world and provides players with an immersive experience.
What Are the Different Types of Haptic Feedback?
There are several types of haptic (i.e., touch) feedback: vibration, force feedback, motion control, and shape memory.
Vibration is one of the most common forms of tactile haptic feedback and involves using motors to generate tactile vibrations. This type of sensation is commonly used in phones and gaming controllers to give users feedback during interactions.
Force feedback technology creates resistance when touched to imitate certain movements like pushing buttons or rotating knobs using quality game controllers and virtual reality systems with actuators.
Motion control haptic feedback allows users to interact with objects on a screen by simulating the physical movements of said objects. This is commonly used in medical training simulations, car racing and flight simulator games, and virtual reality applications.
Shape memory haptics can be used for various tasks such as recognizing shapes, selecting menu items, writing characters, and even making selections from graphical user interfaces (GUIs). It involves using deformable tactile elements that return to their original shape when not touched. This type of haptic response is often combined with force feedback technology.
Modern Use Cases of Haptics
This technology has found its purpose in many diverse fields; we’ll cover the five biggest use categories below.
In medical and therapeutic practices, haptic devices may help train or rehabilitate patients with physical impairments or disabilities. For example, they can simulate sensations such as pressure, weight distribution, temperature, and texture, so patients can gain further control over their motor skills or sensory experience without risking further injury.
Virtual reality devices may provide haptic feedback so that users can physically feel tactile sensations while exploring a digitally simulated environment. Aside from producing sensations felt on the player’s hands or body as they interact with the game, haptic controllers can simulate textures, weight, and forces in driving, flying, and fighting games.
With the rise of virtual reality gaming platforms, haptic gaming controllers will likely become an essential part of most gaming hardware.
Ultrasonic speakers are haptic devices that use high-frequency sound waves, which then move through the surrounding medium and cause tiny particles to vibrate at a rate much higher than normal hearing can detect. This vibration is then translated into tactile sensations, which people perceive as kinesthetic haptic feedback.
Ultrasonic speakers are used in immersive home entertainment systems, providing vibration effects that further enhance the audio experience, sometimes in combination with other haptic technologies.
The combination of haptic devices with wearable devices like smartwatches, fitness trackers, and virtual reality headsets has grown significantly in the past few years. For example, haptics can provide users with information without having to look at a screen, or notify them of incoming messages or calls.
With haptic feedback, users can receive tactile information about buttons or virtual objects on their phone’s touchscreen interface. This allows them to better understand how their device works and make more accurate responses when making selections or navigating menus.
What Does Haptic Feedback Feel Like?
Haptic devices can deliver sensations ranging from small vibrations to more complex physical interactions with objects.
For example, haptic gloves allow users to interact with virtual reality environments by mimicking the feeling of touching or manipulating an object. Gaming controllers might simulate the sensation of firing a gun or hitting obstacles using tactile haptics.
In conclusion, haptic technology is a rapidly developing field that combines sensors and actuators so users can experience tactile feedback when interacting with digital media. It has already become integral to many user interfaces, from wearables to automobiles, with wide-ranging implications for fields such as medicine, gaming, consumer electronics, and more.
Frequently Asked Questions
Gyro aiming was developed for VR gaming and uses motion-sensing gyroscopic sensors. Instead of using a mouse or controller stick, gamers can tilt and move their physical bodies to control in-game aiming.
It's popular with first-person shooters and battle royale games. What’s more, gyro aiming can be used in combination with traditional aiming for a more immersive experience.
Phone haptic feedback allows users to physically feel the effects of their interactions with a device. By using vibrations, phones can provide tangible confirmation that an action has been performed; for example, when users press certain buttons, they may feel a vibration in response.
Haptic feedback is a standard and safe feature of any modern smartphone. If you leave it on, for example, your phone can provide notifications or cues without disrupting your current activities. For instance, when you get a phone call or text message, your phone can vibrate so that you don't have to interrupt what you are doing to make your phone stop ringing.
