When you use a product such as a website or mobile app, on the screen you see many design elements such as a logo, search bar, icons, illustrations, images, etc. All these design elements join together to give you better user experience. When you come in contact with them or say "interact" with them, it is called "interaction design". Here the product means not only websites but can also be a hardware product such as a Microwave Owen, or Joystick or ATM Machine of a Game Console.
What is Interaction Design? (What is Interaction Design?)
The main goal of Interaction Design is to design a product with the help of which the user can achieve his objective better. Interaction Design is always designed keeping in mind three processes - such as Content Strategy (explaining the user through words), Visual Design (presenting interactivity through images, fonts, colors), and Information Architecture (information through correct information give). Interaction can be of any kind such as clicking, pressing, swipe, dragging, or pressing a button. Interaction Design is always designed keeping in mind the behavior and actions of the user.
Principles of Interaction Design
You can also call Interaction Design a part of UX Design, in which the interaction of user and product is given great importance. There are certain principles of Interaction Design that the designer should keep in mind.
1. Goal-Driven Design
It is important to know that what is the goal of giving any kind of interaction in your website / mobile app? How is solving the problem of the user or how will the user benefit from this interaction.
When the user searches for a new house, their first preference is "Location" and you can get the correct information about the location through the map. Magicbricks.com understood this goal of the user and told through Interface design which houses are available for the user in that particular location. With this design, the user can now get information about the exact location of the house.
2. Invisible Design
It is not necessary to have a good visual interface for Interaction, some designs do their work even after being invisible. Invisible Design works according to your user's mental model. With the help of easy user flow, the clear visual design creates confusion in the user which is very important to give better experience.
Scanning the QR Code to connect in WhatsApp Web captures all the information of the user and does not have to fill any form, in the same way when the user orders the food from the swiggy app, he does not think to increase the order quantity Swiggy has placed the button on the right side, on which both sides are shown "arrow", instead he keeps attention on how much quantity he needs for that order and pressing the (-) or (+) quantity works or more It will be done. Here this interface of swiggy is not even designed but it is doing its job quite well.
3. Affordance Design
Affordance Design means such a design of the product itself which tells how the user can interact with it. The user does not need to think much to use such a product.
The interface design of a chair is of any kind, the user will interact with it only to sit or the scissor is of any design, the user will use it with the help of his two fingers.
There are some patterns of Affordance Design according to which their design may be different, but the way to interact with it will be the same. For example, you can press the Lift button or you can only rotate the Knob of the Fan or you have to press the power button up or down to turn ON or OFF. Talking about online, you know that for searching you have to type in the input box and click the Search button. There is no other option for this.
4. Learnability in Design
If you have shown any new functionality in design, then how soon the user will learn how to use it well is also very important for user interaction. Such interfaces are designed keeping in mind the psychology of the user.
That item gets added to your shopping cart by pressing the "Add to Cart" button on the Amazon website. You will see this new functionality in every app these days and the user knows the interaction of this method and uses it very comfortably.
5. Feedback / Response
Good interaction design is the same that gives feedback to the user. The user is alerted or satisfied that something is right or wrong. By giving Feedback or Response, the user trusts your product and it makes it easier to understand your interaction pattern.
A small animation on the wrong Passcode on the iPhone shows that something went wrong. In the same way, there is an animation of Tick Mark on payment on the Paytm App, which shows that something has gone right.
Correcting Interaction Design is very important for a better User Experience. But even today, interactivity and communication between a machine and user are also very lacking. As a designer, we have to understand this and try to provide better interaction through design to the users so that more and more users can use our products/services and we can make progress in the business. It would be a good practice. What do you think about Interaction design, definitely tell in the comments?
