Virtual Reality Technology: Architecture, Tools, Team, and Costs
ScienceSoft has 28 years of experience in 3D modeling and provides professional VR development services.
The Essence of Virtual Reality Technology
Virtual reality is a technology that allows to move multiple activities into the virtual realm and thus reduce the costs, the time, and – in some cases – even the corporeal risks related to performing these activities in biological reality.
Adoption of VR Technology
- The global VR market is projected to reach $22 billion in 2025.
- 90% of the companies with annual income of $100 million to $1 billion to implement AR/VR, Deloitte says.
- In the US alone, the number of VR/AR users is anticipated to exceed 300 million by 2029.
- By 2030, 2.3 million US jobs are expected to use VR/AR techs (compared to the current 80,000 jobs).
- 75% of organizations that adopted AR/VR at scale report 10%+ increase in operational benefits.

How Virtual Reality Works
Architecture
Below is a high-level VR technology architecture that applies to all VR solutions, regardless of their application field.
The key module of the architecture is VR software, which is responsible for:
- Processing of input data, generally received via motion controllers and haptic gloves.
- Feedback generation (including visual rendering) for output devices like HMD and smart glasses and speakers.
- Physics simulation to apply the laws of physics to the virtual world.
- Data load (3D models, audio, video) from the database.
VR software has two-way communication with the cloud databases: software requests and receives from the cloud such key content as 3D models, textures, and audio. All this content can be uploaded to the database (as well as deleted from it) via a web administration panel.
Features
Depending on custom submodules in VR applications, the following features can be introduced:
AI-controlled virtual characters
for introducing virtual guides, assistants, patients, etc.
Motion- and eye-tracking sensor input processing
for rehabilitation VR and motion/gaze-controlled interfaces.
User performance analytics
for VR training or physical therapy software.
Voice recognition
to allow voice-based control and conversations with virtual characters.
Haptics device input processing and feedback generation
for realistic palpable experiences.
In-app video streaming
for media playback in the VR environment.
