Over the past 30 years, I’ve been deeply involved in web development, watching it evolve from simple designs on low-resolution computer screens to the rich and dynamic interfaces we see today. Along the way, new technologies, devices, and user expectations have continuously shaped the way websites are built. However, as we stand on the edge of 2025, it’s clear that smartphone display technology, which has been at the heart of web consumption for over a decade, has reached its practical limits.

So, what’s next? I believe the future of web development lies in moving beyond traditional screens and into the physical world itself. This shift will be driven by augmented reality (AR), a technology that has the potential to revolutionize how we experience and interact with digital content. In this article, I’ll explore what this means for the web and for those of us who build it.

A Brief History: From Computer Screens to Smartphones

In the early days of the web, websites were built for low-resolution computer monitors. Designers had to work within the confines of small, clunky screens. As technology advanced, screen resolutions improved, allowing for more visually appealing and complex designs. The shift to smartphones in the late 2000s brought another major change, requiring websites to be responsive and optimized for touchscreens.

Smartphones revolutionized how people accessed the web, but in recent years, display technology has hit a plateau. Current smartphones offer incredibly high resolutions, but further improvements may not make sense. Why? Because on a device that fits in your hand, increasing resolution too much can make text and images too small to read, especially for people with aging eyesight. Making smartphones larger isn’t a solution either—at that point, they’re more like tablets.

The Next Step: Augmented Reality and the Web

As smartphones reach their limits, it’s time to think outside the box—literally. The next step for web development is to move away from two-dimensional screens and into the three-dimensional space around us. Augmented reality (AR) makes this possible by overlaying digital content onto the physical world.

Imagine standing in a store and seeing detailed product information pop up in front of you, or visiting a historical site and being guided by AR visuals that bring the past to life. These are just a few examples of how AR could transform how we experience web content.

Smart Glasses: The Key to AR’s Future

Today, AR is often experienced through smartphone cameras, but this method is clunky and impractical for everyday use. The future of AR lies in smart glasses—lightweight, wearable devices that display digital content directly in your field of vision.

Smart glasses are already being developed by major tech companies, and while they’re not yet mainstream, advancements in battery life, display technology, and design are bringing them closer to reality. Once these devices become widely available, they’ll provide a seamless way to experience AR, opening up exciting possibilities for web developers.

What AR Means for Web Developers

For web developers, the rise of AR represents a major shift. Designing for AR isn’t just about adapting websites to a new screen size—it’s about rethinking how we present and interact with information entirely. Here are some key considerations:

1. Designing for 3D Space

AR content exists in the real world, not on a flat screen. Developers will need to think about how information is positioned and displayed in 3D space, considering factors like depth, distance, and user perspective.

2. Balancing Information Density

In AR, too much information can overwhelm the user and make the experience frustrating. Developers must carefully balance the amount of content displayed to ensure it’s helpful without being intrusive.

3. New Ways to Interact

Traditional inputs like mouse clicks and touchscreen gestures won’t work in AR. Developers will need to design experiences that use voice commands, gestures, and even eye tracking.

4. Accessibility in AR

Making AR content accessible to everyone, including people with disabilities, will be a critical challenge. Developers will need to consider alternative ways to present information, such as audio descriptions or haptic feedback.

Preparing for the AR Revolution

So, how can web developers prepare for this new era? Here are some steps to get started:

• Learn AR Technologies
  Familiarize yourself with tools and frameworks like WebXR, ARKit, and Unity, which are used to build AR applications.
• Experiment with Prototypes
  Start small by creating simple AR experiences to get a feel for designing in 3D space.
• Collaborate Across Fields
  AR development often requires expertise in hardware, user experience, and even psychology. Working with professionals from other fields can help you create better experiences.

Conclusion: Embracing the Future

The transition from smartphones to AR is inevitable, and it’s an exciting opportunity for web developers to redefine their craft. Just as we adapted to the shift from desktop computers to mobile devices, we must now embrace the challenge of designing for the physical world.

AR isn’t just another trend—it’s a fundamental change in how people interact with information. By preparing now, we can ensure that we’re ready to create meaningful, engaging, and accessible experiences in this new frontier. The future of web development is in our hands—let’s build it.
