Master Thesis: Monocular XR Object Localization with World Models

Ericsson; Stockholms kommun; On-site; SEK 39,000 - 61,000; Full time

Job summary

Ericsson is seeking a Master’s student to investigate world-model-based depth and motion estimation for monocular XR video. The project involves building a Quest-ready capture pipeline with server-side inference and a lightweight distance/projection probe, evaluated against depth sensors.

You will develop a prototype, document datasets, and produce results with recommendations for camera-only XR perception and network-assisted spatial intelligence.

Qualifications

• Master’s degree in XR or spatial understanding, currently enrolled.
• Fluent written and spoken English.
• Experience with Unity and MR/VR programming.
• Experience writing apps for the Meta Quest family is a plus.
• Committed to Ericsson’s values: Professionalism, Perseverance, Respect, Integrity.

Responsibilities

• Build headset RGB-video capture pipeline with server-side inference.
• Train a lightweight probe to estimate object distance and motion while keeping backbone frozen.
• Evaluate the system in controlled scenes with moving objects using ground-truth baselines.
• Assess accuracy, computational requirements, latency, and uplink needs.
• Develop a working prototype for XR perception research.
• Create a documented dataset and measurement setup for reproducibility.
• Present quantitative accuracy and latency results in the thesis report.
• Provide recommendations for camera-only XR perception and network-assisted spatial intelligence.

Job description

About this opportunity

Extended reality (XR) applications need reliable estimates of object distance and motion. However, future lightweight XR and AI glasses may not include dedicated depth sensors because of cost, power, and form-factor constraints.

About this opportunity

Extended reality (XR) applications need reliable estimates of object distance and motion. However, future lightweight XR and AI glasses may not include dedicated depth sensors because of cost, power, and form-factor constraints.

This thesis will investigate whether a pretrained world model, such as NVIDIA Cosmos, can use semantic and scale-related priors to improve metric localization of distant moving objects from monocular XR video. The approach will be evaluated against built-in depth sensing and conventional monocular depth estimation.

What you will do

• Build a headset (e.g. Quest 3) RGB-video capture pipeline with server-side inference.
• Keep the world model backbone frozen and train a lightweight probe to estimate object distance and motion.
• Evaluate the system in controlled scenes with walking people and moving objects, using measured ground truth and depth-estimation baselines.
• Assess accuracy, computational requirements, latency, and uplink requirements.
• Build a working prototype.
• Create a documented dataset and measurement setup.
• Produce quantitative accuracy and latency results.
• Write a thesis report with recommendations for camera-only XR perception and network-assisted spatial intelligence.

The skills you bring

We are looking for a candidate who:

• Is analytical, curious, and open-minded.
• Is fluent in written and spoken English.
• Is studying XR and spatial understanding as a key focus of their Master’s degree at a university.
• Has good knowledge of Unity and MR/VR programming.
• Has previous experience writing applications for the Meta Quest family of headsets; this is an advantage.
• Shares Ericsson’s core values of Professionalism, Perseverance, Respect, and Integrity.
