3DChatApp: Video Chat with 3D Models in Augmented Reality

With the 3DChatApp, EXCIT3D presented a messenger service in 2020 that combines audio and video chat with the display of 3D models in augmented reality. It was intended for medicine and many other industries. Several people could view, rotate and mark the same 3D model at the same time.

Working together on one 3D model

All participants in a chat could show 3D models and view them together. They rotated and scaled the same model, marked it in colour and switched the camera view. Voice communication ran in parallel, and the 3D objects also appeared to the participants as augmented reality models.

Medicine: discussing complex fractures together

The idea was that surgeons could show bones with complex fractures to their colleagues and plan the operation together, even if they are in different places. On our page 3D healthcare solutions and references, the app is listed as a video chat system for surgeons and orthopaedists via smartphone or tablet.

How we also prepare fractures as 3D prints and as AR and VR models for surgery planning is shown in the ORF documentary with EXCIT3D and RIMASYS.

Industry, design and retail

The app was also designed for uses beyond medicine: product designers were to discuss their 3D models internally or present them to customers, and furniture retailers were to let their customers place products virtually in their own homes and try alternatives together with the sales advisor. Friends and acquaintances were also to be able to join the chat with their smartphones.

Presentation to the North Rhine-Westphalian economics minister in February 2020

In February 2020, we presented the 3D medical chat app together with a VR pain therapy to North Rhine-Westphalia’s economics minister Prof. Dr. Andreas Pinkwart and Solingen’s Lord Mayor Tim Kurzbach, together with our partners Prof. Dr. Sascha Flohé (Klinikum Solingen) and Dr. Robert Weindl (CGP-SG).

In May 2020, we presented the app as a video conferencing system with 3D objects and AR for smartphones, intended for medicine, design, schools, architecture and sales, among others.
