What is a Hololens App?

A HoloLens application is not just another piece of software; it is an immersive experience that merges the digital and physical worlds. Running on the HoloLens 2 headset, these applications allow users to interact with 3D holograms that are anchored to their real-world environment. This creates a powerful mixed reality where workers can stay “heads-up and hands-free,” focusing on their tasks while receiving critical information and guidance directly in their line of sight.

The core purpose of these applications is to enhance human capability. They are designed to allow workers to collaborate without boundaries, act with greater precision, and ultimately, increase productivity. Imagine a technician receiving step-by-step holographic instructions overlaid on a complex piece of machinery, or a team of engineers from different continents collaborating on a 3D model of a new building as if they were in the same room. This is the power HoloLens apps unlock.

Key features that define the HoloLens experience include:

• Hands-Free Operation: With built-in voice commands, eye tracking, and intuitive gestures, users can navigate and operate applications even when their hands are occupied with physical tasks.
• Real-Time Collaboration: Applications like Dynamics 365 Remote Assist enable users to share their real-time point of view with remote experts. These experts can then provide guidance, making annotations with 3D digital ink that appear anchored to the objects the HoloLens user is seeing. This drastically reduces downtime and improves first-time fix rates.
• Interactive Training: Applications like Dynamics 365 Guides allow for the creation of step-by-step holographic work instructions. This “learn by doing” approach empowers workers to transfer knowledge, ensure process compliance, and improve efficiency on the job, as seen in the training of nurses on ventilator machines at Sheba Medical Center.
• Data Visualization: Companies like Tokyu Construction use HoloLens to visualize massive 3D building models from 2D blueprints, improving engineering precision directly at the construction site. MDA, a space technology company, uses it to help engineers visualize complex designs and train astronauts.

HoloLens 2 supports a robust ecosystem of applications, including new apps built specifically for the platform, existing applications from the Microsoft Store, and powerful integrations with tools like Microsoft Teams. This allows for holographic screen sharing, file sharing, and text chat, creating a truly hybrid collaboration environment. At its core, HoloLens is an industrial metaverse technology used by industry leaders like Porsche, Eaton, and ZF Group to revolutionize service, drive efficiencies, and empower their workforce.

Reasons It Is Difficult to Develop a Hololens App In-House

While the potential of HoloLens is immense, the path to developing a successful application is fraught with technical difficulties that can easily overwhelm an in-house team without specialized experience. These challenges span the entire development lifecycle, from initial setup and coding to deployment and debugging.

Upgrading Existing Universal Windows Platform (UWP) Applications

Many organizations hope to leverage their existing UWP applications to create a HoloLens experience. However, this is far from a simple port.

• Unsupported APIs and Features: HoloLens does not fully support many standard UWP APIs and features, including Notifications, File Explorer, Messaging, and tiles. Manually identifying every unsupported API call within a large, existing codebase and then implementing a functional alternative is an incredibly difficult and time-consuming task.
• No Compiler Warnings: To compound the problem, Visual Studio does not generate compile-time errors or warnings for these unsupported APIs. An application might build successfully but then fail unexpectedly on the device, leaving developers to hunt for the root cause without clear guidance. This requires meticulous, manual code analysis and robust testing protocols to ensure required functionality is not broken.
• Push Notification Workarounds: Even a seemingly straightforward feature like push notifications is not fully supported, forcing developers to implement complex workarounds using lower-level networking APIs to replicate the functionality.

User Experience and Interface Challenges

Designing for mixed reality is a fundamentally different discipline than designing for a 2D screen.

• Limited Viewport: The HoloLens viewport, where holograms are visible, appears within a small rectangular box in the center of the user’s vision. This requires a complete rethinking of UI/UX design. Users must constantly remember where they have placed holograms in the physical space, and developers must design interfaces that guide the user’s attention effectively without feeling constrained.
• Poor 2D and 3D App Experience: Simply deploying an existing 2D UWP app on HoloLens confines it to a flat 2D window. This provides a poor user experience, especially when handling gestures, as a user’s hand can easily move outside the window’s boundary. Similarly, running an existing 3D application “as-is” results in a subpar experience because it lacks integration with the physical world.
• Complex Input Implementation: HoloLens relies on gestures and voice commands. Adding these to an application is not trivial. Furthermore, custom gestures (like a circle gesture or specific swipes) that may have been used in a mobile app are very difficult to make work reliably on HoloLens. Identifying the precise position of the user’s hand in a 3D frame to trigger these interactions is a significant technical hurdle.
• The “Suspended App” Problem: A particularly frustrating issue occurs with 2D UWP apps. When a user performs a swipe gesture, their gaze can point outside the 2D app’s frame. This action can push the entire application into a suspended mode, at which point it can no longer recognize any gestures at all, rendering it unresponsive.

Deployment, Debugging, and Environment Hurdles

Even after overcoming design and coding challenges, getting the application onto a device and fixing bugs presents its own set of problems.

• Deployment Errors: Deploying to a physical HoloLens device requires using its internal IP address, not the external one provided by Cortana. An incorrect IP mapping leads to a “DEP8000: Unexpected deployment failure” error, which can be cryptic to a novice team.
• Vague Error Messages: The debug console often displays unhelpful error messages. For example, instead of stating “Application already installed,” it might simply say, “Please contact your software vendor,” sending developers on a wild goose chase. Other issues, like the program exiting with “code 255 (0xff),” offer little information for debugging.
• Tooling and Environment Setup: The initial setup is a challenge in itself. Correctly installing the required Windows 10 SDK, HoloLens Emulator, and Visual Studio 2015 is critical. An improper installation can lead to a host of issues: the emulator might not appear in Visual Studio’s device list, the design mode in the XAML editor may display warnings, or the emulator itself might have network adapter problems. This complex configuration, along with potential issues in Hyper-V management and NuGet package manager settings, creates a high barrier to entry.

Different Types of Hololens Apps

While HoloLens supports a wide range of applications, they can be broadly categorized by their primary use case, reflecting how industries are leveraging mixed reality to solve real-world problems.

Collaboration and Remote Assistance

This is one of the most powerful and immediate applications of HoloLens technology. These apps are designed to bridge geographical distances and bring expert knowledge to any location.

• Dynamics 365 Remote Assist: This is a flagship HoloLens application. A frontline worker can initiate a heads-up video call, sharing their real-time view with a remote expert who could be anywhere in the world. The expert, using Remote Assist or Microsoft Teams, can see what the worker sees and provide guidance by placing holographic annotations and instructions directly into their physical environment. ZF Group uses this to help employees share knowledge and troubleshoot in real time.
• Holographic Microsoft Teams: This integration brings the familiar collaborative tools of Teams into mixed reality. Users can join meetings, share their screens as holograms, and streamline discussions with file sharing and text chat, all within the HoloLens interface, enabling truly effective hybrid collaboration.

Training, Guidance, and Knowledge Transfer

HoloLens is a revolutionary training tool, allowing employees to learn by doing in a safe, repeatable, and interactive way.

• Dynamics 365 Guides: This application allows organizations to create standardized, step-by-step holographic instructions. Deskless workers can follow these guides to ensure process compliance, improve efficiency, and learn complex tasks on the job. Porsche Cars North America uses Guides to help dealer partners maintain customer vehicles, revolutionizing their service experience. Sheba Medical Center famously used HoloLens to train staff on the complex operation of ventilator machines during a critical time.
• Knowledge Transfer: These applications are critical for empowering workers to transfer knowledge from one generation to the next, capturing the expertise of seasoned employees in an interactive format that new hires can access on demand.

Design, Visualization, and Manufacturing

For industries that work with complex 3D data, HoloLens offers an unparalleled ability to visualize and interact with designs in the context of the real world.

• Engineering and Construction: Tokyu Construction uses Azure Remote Rendering on HoloLens 2 to visualize full-scale 3D building models from 2D blueprints, allowing them to improve engineering precision and increase productivity on site.
• Aerospace and Advanced Manufacturing: MDA uses HoloLens 2 to create immersive mixed reality experiences for its engineers. This allows them to visualize intricate designs, accelerate the diagnosis of issues, and even train astronauts and ground controllers on complex systems. Eaton’s Vehicle Group also leverages mixed reality to drive significant savings and efficiencies in their processes.

Dedicated Business Functions

HoloLens can also be configured to serve a single, specific purpose, making it a powerful tool for focused tasks or public-facing demonstrations.

• Kiosk Mode: This feature allows the device to be locked down to a single app or a specific set of apps. This is ideal for creating dedicated business solutions, such as an interactive product demo at a trade show or a fixed-purpose tool on a factory floor, ensuring users only access the intended experience.

Cost Estimate for Developing a Hololens App

Estimating the full cost of HoloLens app development requires looking beyond the price of the software and hardware tools. While these initial costs are fixed, the primary driver of the budget will always be the cost of the skilled development talent required to build the application. However, understanding the baseline costs for tooling is a critical first step in planning your project.

Here are the key hardware and software costs you can expect:

These costs represent the foundational investment needed to even begin development. The real cost lies in the hours spent by developers, designers, 3D artists, and project managers. Given the significant challenges outlined earlier—from navigating unsupported APIs and designing a novel UX to debugging cryptic errors—the time required for an inexperienced team can be immense.

A complex HoloLens project can easily take thousands of developer-hours. Partnering with a specialized agency that has already mastered the HoloLens development environment can dramatically reduce these hours, control costs, and mitigate the risk of project failure. The initial investment in expert guidance often pays for itself by avoiding costly mistakes and accelerating the timeline from concept to a functional, value-adding application.

Why Integrating Hololens with Mobile Apps is Hard (And How We Can Help)

Many businesses envision a connected ecosystem where a mobile app works in concert with a HoloLens experience. For instance, a manager on the go might use a tablet app to assign tasks and review data that a frontline worker then accesses holographically on their HoloLens. While powerful, integrating these two worlds presents a significant technical chasm that can be difficult for in-house teams to bridge. This is where our deep expertise at MetaCTO becomes invaluable.

One of the greatest hurdles is the disconnect between the UWP frameworks. A technical challenge for integrating existing mobile UWP applications is the need to implement replacement APIs for mobile-specific features like Notifications, File Explorer, and Messaging that are not available on HoloLens. Manually identifying every unsupported API and feature and then engineering a reliable alternative is a monumental task. Further complicating this, Visual Studio offers no compile-time warnings for these incompatibilities, creating a minefield of potential runtime failures. Our experienced developers have navigated this landscape before. We have the processes in place to perform the thorough code analysis required, identify these API gaps, and implement robust workarounds, ensuring your application remains stable and functional.

User experience is another critical failure point. A 2D mobile interface does not translate directly to a 3D holographic space.

• Running a 2D UWP app as-is on HoloLens creates a clunky, limited experience within a flat window.
• Porting a 3D mobile app (like one made in Unity) directly results in a poor user experience because it isn’t designed for spatial mapping or sound.
• Implementing custom gestures is notoriously difficult, as is identifying hand position in a 3D frame. A common but frustrating issue is when a simple swipe gesture causes a 2D app to enter a suspended mode, making it unresponsive.

At MetaCTO, our process begins with strategy and design tailored to the specific platform. We don’t just port; we re-imagine the experience for mixed reality. We design intuitive interfaces and input systems (gestures and voice commands) that feel natural on HoloLens, avoiding common pitfalls that lead to user frustration.
