Component Crawler for Mixed Reality Projects

December 16th, 2021 | by

For mixed reality applications, developers usually choose a modular development approach where the application-logic is segmented into separate components which only realize one feature. In well-designed projects, the components are reusable in different contexts within the project but also outside of it. Additionally, code from these projects can be used to find examples how to use APIs or libraries. However, many elementary features of mixed reality applications are re-implemented in new projects, instead of leveraging components from existing open-source projects.

Persistent Association of Virtual Objects in Mixed Reality

December 16th, 2021 | by

A mixed reality environment immerses users in a three-dimensional space. This allows them to organize digital content in the entire room, e.g. task cards in immersive project management. A natural way to sort related objects is by placing them close to each other. However, this kind of spatial co-location of objects is not enough to stress their relation to each other. If another user who is unaware of the association moves one of the objects, the spatial connection is lost. Hence, lines in 3D space are required which establish a visual and persistent connection between the objects. In a previous project, an initial system was implemented which uses straight lines to connect the objects. However, straight lines have some shortcomings since they intersect with obstacles between the two endpoints. A better connection system can use 3D curves to avoid the obstacles in an efficient way.

Immersive 3D Presentations for Education

December 16th, 2021 | by

Lectures convey 2D content on slides that are projected onto a wall but the understanding of 3D structures is important in anatomy courses or engineering. Moreover, the legibility varies based on the position in the lecture hall due to the angle and distance of the viewer which can influence the learning efficiency. Mixed Reality has the ability to immerse the viewer in the presentation. Since participants can use their own hardware, e.g. smartphones, to view 3D presentations, content can be positioned individually at the optimal location for every person. Additionally, presentations can vary in scale, ranging from miniature 3D models that are displayed on the table of every member in the audience to above-life size close-ups. Lecturers can use the same 3D presentation for remote teaching if face-to-face lectures are not possible.
