Common Small Touch Targets in Gaming Apps: Causes and Fixes

Small touch targets are a common issue in gaming apps, where interactive elements, such as buttons or icons, are too small to be easily tapped or clicked by users. This problem can lead to frustration

Introduction to Small Touch Targets in Gaming Apps

Small touch targets are a common issue in gaming apps, where interactive elements, such as buttons or icons, are too small to be easily tapped or clicked by users. This problem can lead to frustration, errors, and a poor user experience.

Technical Root Causes of Small Touch Targets

The technical root causes of small touch targets in gaming apps can be attributed to several factors, including:

• Insufficient screen real estate: With the increasing variety of screen sizes and resolutions, gaming apps may not be optimized for all devices, leading to small touch targets.
• Poor UI design: Inadequate consideration of user experience and finger size can result in small touch targets.
• Inconsistent layout: Inconsistent layout and spacing between elements can make it difficult for users to accurately tap on small targets.

Real-World Impact of Small Touch Targets

The real-world impact of small touch targets in gaming apps can be significant, leading to:

• User complaints: Frustrated users may leave negative reviews, complaining about the difficulty of using the app.
• Low store ratings: Poor user experience can result in low store ratings, affecting the app's visibility and downloads.
• Revenue loss: A poor user experience can lead to a decrease in in-app purchases and revenue.

Examples of Small Touch Targets in Gaming Apps

Here are 7 specific examples of how small touch targets can manifest in gaming apps:

1. Small buttons in menus: Buttons in game menus, such as "Start" or "Options," may be too small to tap accurately.
2. Tiny icons in HUDs: Icons in heads-up displays (HUDs), such as health or score indicators, may be too small to tap or read.
3. Close proximity of elements: Elements, such as buttons or icons, may be placed too close together, making it difficult to tap on the intended target.
4. Small text inputs: Text input fields, such as those used for player names or chat messages, may be too small to type in accurately.
5. Minimap buttons: Buttons on minimaps, such as those used to toggle between different views, may be too small to tap.
6. Small joystick or D-pad: On-screen joysticks or D-pads may be too small to control accurately.
7. Tiny inventory management buttons: Buttons used to manage inventory, such as "Equip" or "Drop," may be too small to tap.

Detecting Small Touch Targets

To detect small touch targets, developers can use various tools and techniques, including:

• Visual inspection: Reviewing the app's UI and layout to identify potential small touch targets.
• User testing: Conducting user testing to observe how users interact with the app and identify areas where they struggle.
• Automated testing tools: Using tools like SUSA, which can automatically explore the app and identify small touch targets.
• Heuristics-based evaluation: Evaluating the app's UI against established heuristics, such as those outlined in the WCAG 2.1 AA guidelines.

Fixing Small Touch Targets

To fix small touch targets, developers can:

• Increase element size: Increase the size of small elements, such as buttons or icons, to make them easier to tap.
• Improve layout: Improve the layout and spacing between elements to reduce errors and make the app more usable.
• Use clear and simple language: Use clear and simple language in text inputs and buttons to reduce errors and make the app more accessible.
• Provide alternative controls: Provide alternative controls, such as voice commands or gestures, to make the app more accessible.
• Implement zoom functionality: Implement zoom functionality to allow users to enlarge small elements and make them easier to tap.

For example, to increase the size of a small button in Android, developers can use the following code:

Button button = (Button) findViewById(R.id.button);
button.setMinimumHeight(48); // minimum height for a button
button.setMinimumWidth(48); // minimum width for a button

Similarly, to improve the layout and spacing between elements, developers can use a layout manager, such as LinearLayout or RelativeLayout, to arrange elements in a way that reduces errors and makes the app more usable.

Prevention: Catching Small Touch Targets Before Release

To catch small touch targets before release, developers can:

• Conduct regular user testing: Conduct regular user testing to identify areas where users struggle and make improvements before release.
• Use automated testing tools: Use automated testing tools, such as SUSA, to identify small touch targets and other usability issues before release.
• Implement accessibility guidelines: Implement accessibility guidelines, such as those outlined in the WCAG 2.1 AA guidelines, to ensure that the app is usable by all users.
• Use design systems: Use design systems to ensure consistency in UI design and layout, reducing the likelihood of small touch targets.

By following these best practices, developers can catch small touch targets before release and ensure that their gaming app provides a good user experience for all users.
