Affordance is a concept in design that refers to the possible actions or uses that an object or environment offers a user. It is the relationship between an object and the person using it and what the person perceives they can do with the object based on its physical characteristics.
In other words, affordance is the quality of an object that suggests its potential usefulness and how it should be used. For example, a doorknob affords turning or pushing, while a chair affords sitting. These actions are suggested by the physical features of the objects themselves and can be understood without any extra instructions or explanations.
Affordance is essential in design because it can significantly affect the user experience. When an object has clear and intuitive affordances, users can easily understand how to interact with it and feel comfortable doing so. On the other hand, objects with clarity or misleading affordances can frustrate users and lead to clarity and mistakes.
Designers can use affordance to their advantage by ensuring their objects have clear and straightforward possible actions or uses. This can be accomplished through shape, color, texture, size, and other physical attributes that suggest specific interactions. By paying attention to the affordances of their designs, designers can create intuitive and user-friendly products.

Affordances Examples Explained
1. A light switch affords pressing or flipping.
A light switch controls the lights in a room. The word “affords” means that the light switch allows or provides for something – in this case, it affords pressing or flipping. This means you can push or flip the switch to turn on/off the lights. For example, if you want to turn on a lamp in your room, you would press or flip the switch on its base to activate it. Similarly, when leaving a room at night, you can use the same method of pressing or flipping to turn off your lights before bed.
2. A camera with a shutter button affords pressing to take a photo.
A camera has a shutter button, which you can press to take a photo. Again, the word “affords” means that you can do this with the camera because of its design. Pressing the shutter button is one of its features or capabilities. If you want to take a picture with this kind of camera, you must find the shutter button and press it.
3. A car steering wheel affords turning and driving.
A steering wheel affords turning and driving. You can turn the car left or right using the steering wheel and move it straight ahead. The steering wheel helps you control where your vehicle goes while driving.
4. A computer mouse affords clicking and scrolling.
A computer mouse is used to control your computer. It helps you move the cursor on the screen so you can click on things, like buttons or links. You can also scroll up and down using the wheel in the mouse’s middle. This makes it easier to read lengthy documents or websites without having to click on arrows or drag a scrollbar constantly. A computer mouse allows you to interact with your computer more quickly and efficiently.
5. A tablet with a touch screen affords tapping and swiping.
A tablet has a touch screen, which means you can control it by touching the screen with your fingers instead of using buttons or a mouse. The touch screen allows you to tap on icons or swipe your finger across the screen to move from one page or app to another. This means that if you have a tablet with a touch screen, you can control it just by tapping and swiping on the screen with your fingers.
6. Buttons on a remote control afford pressing to change channels or adjust the volume.
Buttons found on a remote control can be used to change the TV channel or adjust the volume of the sound coming from your TV. When you press these buttons, they send signals to your TV telling it what to do. For example, if you want to watch a different channel, press one of the channel-changing buttons on your remote control, telling your TV to switch channels. Similarly, if you want to make the sound louder or quieter, you would use the volume adjusting buttons on your remote control, which sends signals that tell your TV how loud or soft it should be.
7. Icons on a smartphone home screen afford tapping to access apps.
Icons are small pictures or symbols on a smartphone’s home screen representing different apps. When you tap on an icon, it opens up the corresponding app and allows you to use its functions. For example, if you tap on the phone icon, it will open up your phone app so you can make calls. The icons act as shortcuts to quickly access your desired apps without searching for them in menus or folders.
8. A stovetop burner affords turning a knob to adjust the heat.
A stovetop burner has a knob that you can turn to adjust how hot it gets. This means that if you want your food to cook faster, you can turn the knob up to make the burner hotter. And if you want your food to cook more slowly, you can turn the knob down so that the burner is cooler.
9. A bicycle handlebar affords turning to steer and balance.
A bicycle handlebar helps you turn the bike in different directions and also enables you to balance while riding. So, when you want to go left or right on your bike, you can use the handlebar to turn it in that direction. The handlebar also helps keep your body balanced as you ride along so you don’t fall off easily. It is essential to a bicycle because it allows for control and stability while riding.
10. Keys on a keyboard afford typing and pressing.
The keys on a keyboard are designed for two main actions: typing and pressing. Typing involves using the keys to input letters, numbers, symbols, and other characters into a computer or device. Pressing refers to using the keys to perform specific functions such as opening programs, navigating menus, or executing commands. The design of each key is carefully crafted to make it easy and comfortable for users to type quickly and accurately while allowing them to press with precision when needed.
