Improving Trade Show Presentations Through Interactive XR Product Demos
At global trade shows, companies usually have a limited number of advanced diagnostic machines to present due to size and logistical constraints. To provide a more complete and immersive product experience, Siemens Healthineers partnered with Nomtek to develop an Apple Vision Pro application that allows booth visitors to explore multiple machine variants, attachments, and configurations, without the physical limitations of the event space. The application includes a remote-control mode to make the demo experience more accessible and flexible.
Showcasing Complex Medical Equipment in Spatial Environments
Diagnostic machines are often large, complex, and difficult to transport. Yet seeing and understanding their features is critical for buyers and stakeholders, especially in high-stakes environments like international trade fairs.
To solve this challenge, Siemens Healthineers wanted a spatial solution that would allow users to view and interact with various machine configurations. We delivered a RealityKit-based Vision Pro app that lets trade show visitors explore high-fidelity 3D models of Siemens Healthineers’ medical devices — including attachments and modular variants — while offering real-time control from an iPhone to guide the experience. This setup removed the need to configure the headset for each individual and helped guide users through the UI, letting marketing teams adjust the demo to each conversation.
“We had a tight timeline and high expectations — Nomtek delivered. The app became a key part of our sales pitch and helped us open important conversations with partners and investors. What impressed me most was how quickly they understood our goals and adapted the design to match exactly what we needed for live demos.”

Scope of Work: Building an Immersive Trade Show Tool with Modular Control
This project required technical execution and iterative collaboration with Siemens Healthineers’ internal stakeholders. The goal was to build a functional and visually engaging demo application for Apple Vision Pro. The work was structured into six key areas:
Discovery and Concept Validation
We began with in-depth discussions to understand Siemens Healthineers’ trade show goals and how spatial technology could support them. This included evaluating how best to present complex diagnostic machines virtually and identifying potential interaction patterns that would resonate with event audiences.
3D Model Adaptation and Iteration
The base 3D assets provided by the client required optimization for spatial use. We improved and adapted these models for performance and clarity in RealityKit.
UX/UI Design for Demo Environments
We designed a clean, event-friendly interface that allowed quick viewing of medical device models. The UI was customized for headset users while remaining adaptable for future external control methods.
Prototype Development and Internal Testing
A functional prototype was built and delivered early in the project. We conducted demo sessions with Siemens Healthineers’ marketing department, gathering insights into how the app would be used and what adjustments were needed to support different presentation scenarios.
Solution Refinement and Remote Control Integration
Based on feedback, we introduced a second interaction model that enabled remote control via iPhone, eliminating the need for headset users to perform setup themselves. This significantly improved demo flow and made the application easier to operate in high-traffic environments.
User Testing and Roadmap Planning
The updated application was tested at an internal Siemens Healthineers event. We observed usage, gathered further feedback, and held follow-up sessions to discuss future improvements, including the development of a Mac-based launcher to simplify headset setup.

Solution
The application lets users explore diagnostic machine models in high detail, displayed at full scale in an immersive environment. It provides the flexibility to demonstrate product variants that would be impossible to physically bring to an event.
The initial app allowed headset users to control and navigate the experience themselves. However, through testing and iteration, we introduced a second mode where the demo can be controlled remotely from an iPhone, making it easier for marketing staff to guide the experience and align it with the sales narrative.
Built with Swift, SwiftUI, and RealityKit, the application delivers stable performance and visual clarity tailored to Apple Vision Pro.
Impact: More Machines, Less Setup, Better Conversations
The Vision Pro app gave Siemens Healthineers the ability to showcase machine models without transporting physical units, saving cost and space at trade shows. Remote control via iPhone improved demo flow, allowing staff to guide interactions and focus on the conversation. The result was a more flexible and scalable way to present complex medical equipment in any setting.
Team Composition
For this project, a select team of spatial development and augmented reality experts was put together to bring value and advice at every step.
