To defray information to a user or operator in the form of advanced vibration patterns and waveforms is known as haptic feedback. From the Greek phrase “I touch” haptics word has been taken form. Haptic feedback comes from the concept of using touch to communicate with the operators. Human beings are enriched with five senses but electronic devices mainly communicate with two senses and these are sight and view. Haptic feedback changes this by imitating the sense of touch. Haptic feedback is not a specific application. it’s just a genre of communication between machine and human being.
Haptic uses a pulsating element like a linear resonant actuator and rotator which is utilized by an electronic circuit. All the inner mechanisms are monitored by a microcontroller because the microcontroller has a memory that’s why it can decide when to vibrate and using that pattern, and for a devoted haptic driver, chip to monitor the actuator.
Back in the 1980s, computer researchers were trying to find a solution regarding haptic feedback. We will figure out how haptic technology works,
- Describing computer haptics to the related area of haptics research.
- Distinguish the types of haptic feedback requisite for virtual touching.
- Researching haptics systems whether it is in progression or currently available in the market.
- Analyzing current and dynamic applications.
The places where you’ll be able to find Haptic feedback
Primitive LEDs and other notification systems are still useful in many applications in the present age, but there are a lot of products where you can enhance the functionality of that product by implementing hearing and sight with our sense of touch. After adopting haptic feedback manufacturers are highly benefited. The reason it can enhance the user perception by building touch and display interfaces which are respectively cheaper to construct than a control panel with switches. In this way designers also get benefited because they can make context-tangible UI by changing the graphical layout.
Haptics can also raise the performance of the users. Drivers can concentrate on driving by using a pulsating device to send information through the system. From simpler input authorization to fire and smoke alarm, even positioning information, the haptic feedback system is diversely used now a day in our daily life. In the case of tablet pc you can the benefits of haptic feedback. You can type on a touchscreen on a computer keyboard. The haptic feedback qualifies the user to type quickly with a minimum number of mistakes.
How do you Create Haptic Feedback Easily?
The somatosensory system is like a tangible sensation when most people are thinking to say “touch”. This encircles an extensive variety of sensations like vibration, pressure, also pain, temperature and also senses the movement of your body in space.
The somatosensory system comprises at least 12 specific types of receptors. Each transmits difference data to your brain. These receptors are everywhere inside and outside the surface of your body. Imitating the somatic sensor is a herculean task. Yet, as the comprehensive use of simple vibrotangible technology in cell phones and gaming, haptic can be very effective in this way.
What is Haptic technology?
The weeny apparatus that creates vibration in a mobile phone is the best example of Haptic technology, there are several ways to initiate touch. Few are like “Ultrahaptics” ultrasound, technology, generate the tangible sensation in mid-air and don’t even needful for the user to be in contact with a natural surface.
Nowadays the ranges of haptic technology are very wide its starts from the vibration in mobile using wearables, regulator, and mid-air haptics up to very high-end exoskeleton and entire bodysuits
Haptic technology is now penetrating every sector from automobiles to Gps-based entertainment, from marketing to army training. Haptics industry is prominent to be valued over $19 billion by 2025.
Haptic feedback vs Vibration alert?
This is an are of contradiction, that is because of no specific guidelines as to what differentiates these two. In reality, both of them are very analogous. Though both of them use vibration to cohere with the user, the main distinction is that the haptic device mostly uses diverse flourished waveforms to pass on information to the user. Vibrating alert products are less flourished and designed to generate a strong pulsation to inform the user.
In the case of reversing the car’s parking sensor when it coming within a 50cm radius of an object, the steering wheel starts to vibrate. This is a simple case of vibrating alert with a simpler vibration pattern. But in this case, the driver only knows that there is an object nearest to him but he is not aware of the distance of that object, to resolve this problem haptics technology has been introduced, using this technology driver can get an idea about the range and distance of that object. You can eliminate high volume beeping sound coming out from current car sensors using haptic feedback and assure that in a crowdy environment the driver can use the parking sensors properly.
Why Haptic feedback is a friendly tool for product designers?
In this technology, designers get a lot of benefits because they need to build touch and type display or layout in place of the switch and buttoned layout where they can change the context-tactile user interface by changing the graphical layout only. Product designers get benefited most by using haptic feedback as a new advanced tool. Haptic feedback is the consumption of work that enhances the contact between audio nad visual and increase the scope of inventing new products.
Types of Haptics
Generally, we receive two types of feedback
- Kinetic
- Tactile
What is Haptic learning Process?
Nowadays teachers are mostly assessing their students learning style to check whether the students are capable of adapting their teaching methods or not. How a person learns best it’s his or her learning style. There are many learning style models present but the best model emerges on impressionable input.
There are three types of learning style
- Auditory
- Visual
- kinesthetic
an investigation is saying that audio and visual learning is most effective because these two involved in sensation and touch. A review says that using haptic technology high school students raised their positive behavior towards science and technology and getting a clear concept. Using haptics topics like viruses, bacteria, and many other particles which very nano in size is getting easy to teach. Cell division of animals and other inner bodies mechanism can be taught very easily.

How IOS use haptic feedback
The UIFeedbackGenerator class is providing the functionality of haptic feedback. UIFeedbackGenerator class is available in UIKit from iOS 10.0+ version. As the UIFeedbackGenerator class is an abstract class that’s why we cannot use this directly by creating a child class of it.
Following concrete, child classes are using to trigger Haptic feedback.
UIImpactFeedbackGenerator. To indicate that an impact has occurred impact feedback generator class is mainly used. When a UI object strikes with something you can trigger impact feedback. There are three types of intensity variations, light, medium and high.
UISelectionFeedbackGenerator
To preface a change in the selection or to indicate the mode of selection feedback generators are mainly used. There are three various modes: success, warning, error.
UINotificationFeedbackGenerator
To notify the success, failure, warnings notification feedback generators are mainly used.
Use of feedback generator
Instantiate the generator class
Instantiation of one of the UIFeedbackGenerator class’s concrete child classes is compulsory to create feedback.
Generator preparation
Performing this step is not compulsory, you can do it if you want to do it. This will cut off the feedback trigger time delay up to some extent. This step is mandatory if you are trying to equal feedback to sound or visual clues.
How to trigger feedback
Every child class of feedback generator has a unique triggering method. Before triggering feedback generator it is necessary to call the exact method: impact occurred(), selection changed(), notification occurred(). But make it clear that haptics does not play directly by calling these methods. At first, it notifies the system of the event, and then the system ordains whether to play the haptics based on the device, the state of the application, remaining battery and other factors.
Keep in mind a few points regarding haptics
Make it sure you always use feedback for aimed purpose, the way haptic feels don’t select it blindly.
The feedback source should be clear to the user. Taking an example, in the UI screen feedback must have to match with a visual change, or must be matched with the response of a user action.
Try to avoid the overuse of feedback, because it can cause clutter and knock off the importance of feedback.
Concluding Note…
Try to follow the system and let the system ordained whether it should play feedback. Try not to check device type to conditionally trigger feedback. Once you have decided how you want to use feedback, make sure you trigger it when the adequate events occur. Hopefully, this article will help you a lot to utilize the product designing program with ease.
