A button is just something you press to get a task done. Or is it? Buttons do just about everything, which is why they come in an almost endless variety of shapes and sizes, each tailor-made for the task at hand. We wanted to take a closer look at what makes a button work best so we could design one that acknowledges the very specific needs of patients with rheumatoid arthritis or psoriatic arthritis.
Building a better button
Think about the buttons you interact with every day.
From coffee machines to the buttons on a remote control—even the keys on your computer—buttons are tailored to their task in terms of shape, placement, and ease of use.
Some buttons are intentionally designed to require more effort than others, such as those activating potentially dangerous machinery. But buttons we use every day, like an elevator call button, are usually designed to be as simple to use as possible.
Buttons are usually designed to be as simple to use as possible
Buttons are designed to take what the user is doing into account.
They include mechanisms that make for a better end-to-end user experience to carefully align function with the user's intent and mitigate the associated risk of inadvertently pushing the button.
For instance, if you want to force shutdown your computer, you'll need to press not one but three buttons—Control, Alt, Delete. In a similar fashion, it may only take the press of a button to start your car, but in many cases, you'll have to hold the brake pedal down simultaneously to make sure you don’t suddenly accelerate into traffic or a garage door.

Form factor: shape, size, and materials
Many factors influence a button’s shape.
You may have noticed that certain buttons feel like second nature to operate, like the buttons on a computer mouse. While not particularly large or obtrusive, the shape, placement, and ease of clicking mean the user often doesn’t need to look at the buttons to know how they function, relying instead on their sense of touch and intuition.
Other buttons are made to be extremely large, allowing them to be pressed from a variety of angles. For example, a button to open a hospital door is very large and requires low push accuracy so that you can even press it with an elbow if you’re in a wheelchair or using crutches. A button’s use also dictates the material used in its construction. These can range from soft plastics for light usage to metal that allows the button to withstand heavy use or exposure to the elements.
Location, location, location
Where a button is placed can say a lot about a button’s intended use.
It’s not surprising that buttons are often placed where they can most easily be used. Take arcade games for instance. There’s a good reason buttons are placed on top of a joystick and on the sides of a pinball machine. It’s a location comfortable to the hand and suited for the task. Similarly, monitor buttons are often placed along the bottom where interacting with them does not block the screen.
Some buttons are easier to press than others.
While some buttons intended for repeated use are made to be easy to press, others can require more force to activate.

We wanted to create an injection device with an activation button specifically designed to meet the needs of RA and PsA patients
The button is placed at a slightly downward angle for easier accessibility.
Like a car that requires the brake pedal be pushed to start it, Enbrel Mini® with AutoTouch® has a skin sensor to confirm the user’s intent
Like the buttons on an elevator or a dishwasher, AutoTouch® only requires a simple press and release of the button for activation

A BUTTON BUILT FOR RA AND PsA
Enbrel Mini® single-dose prefilled cartridge with AutoTouch® reusable autoinjector automates the injection process with a press and release of a button.
Cognizant of the needs of moderate to severe rheumatoid arthritis (RA) and psoriatic arthritis (PsA) patients, we set out to design an autoinjector with a button to help minimize the amount of force needed to activate it. A typical computer key takes approximately 13 newtons to activate while the Enbrel Mini® with AutoTouch® only takes a maximum of 5.56 newtons—that’s less than half the force of pressing a computer key! In fact, validation testing of 66 autoinjectors revealed that the actual amount of force needed was even lower, ranging from 1.7 to 2.9 newtons. And if you’re wondering if such a sensitive button could make misfires a problem, we thought of that too...
Skin Sensor Confirmation
Because the button requires such little force to press, we equipped Enbrel Mini® with AutoTouch® with a mechanism to help prevent accidental injections: a skin sensor that doesn’t allow the injection to proceed unless it detects that the device is in proper contact with the skin.
Research revealed that a button placed on the side of the device was challenging for those with larger hands. Thus, the button was placed at an angle at the top, giving patients the ability to trigger the device with their thumb. In addition, the flange around the button was minimized, enabling better accessibility.
The button on the Enbrel Mini® with AutoTouch® is tapered to allow for activation while reducing the need for the user to adjust their grip on the device. Find out how patients are getting a handle on grip with AutoTouch®.
OPERATING THE BUTTON
Besides its shape, placement, and the pressure required for activation, the button on the AutoTouch® was designed with other features to help patients successfully complete the injection process. See more features of AutoTouch® in action.
Press and release
There are plenty of buttons that aren’t required to be continuously held down in order to function. Instead, the buttons we use every day, such as garage door openers, elevator buttons, and dishwasher buttons, require only a quick press and release.
In the same way, the button on the Enbrel Mini® with AutoTouch® does not need to be held down throughout the injection process. Instead, a simple press and release of the button begins the injection.
Communicating key information
The button on the Enbrel Mini® with AutoTouch® also has several features that convey important information to the user throughout the injection process. Prior to the injection, a light in the button illuminates green, letting the user know that the device is ready to inject. During the injection, the light flashes, showing the user that the injection is in progress, and the green light stops when the injection is complete.
In addition to the button light, Enbrel Mini® with AutoTouch® has redundant communication features, such as an LCD progress bar on the side and an audio chime when the injection is complete. That way, the user has multiple feedback mechanisms throughout the injection process.
PURPOSE-BUILT FOR RA AND PsA PATIENTS
There's nothing simple about designing a simple button.
We thought about placement, shape, size, push pressure, and lighting so we could make a button suited for RA and PsA patients. Ultimately, the button on the AutoTouch® may seem inconsequential, yet it has a real-world impact on our RA and PsA patients—and that's what matters to us.
