Interactive Hologram Projection with Direct Hand Interaction

3D holograms become tangible: With FlexiVol, users can reach directly into a light field for the first time – without a headset or gloves.
A New Dimension of Interaction: The Hologram Becomes Tangible
What if you could not only see a hologram, but also touch it? FlexiVol makes this possible: a new type of volumetric display that projects three-dimensional content in a way that users can interact with – using only their bare hands. No headset, no gloves. The technology combines an elastic projection surface with intelligent light control and motion detection.
The highlight: the user’s hand can physically enter the projected volume without compromising the optical integrity of the projection. The light field adapts to hand movement in real time, enabling a new form of intuitive interaction.

How Does the FlexiVol Technology Work?
FlexiVol is based on a combination of flexible volumetric light, an elastic scattering surface, and AI-powered motion detection. Instead of rigid materials like those used in conventional volumetric displays, it employs a vibratory diffuser. This surface is illuminated with dynamic light that responds to shape changes caused by hand movements.
The result: a three-dimensional scene that is not only visible but also tangible. Through adaptive light steering, the projected image remains stable even when users reach directly into the display.

Applications in Industry, Medicine, and Interface Design
Whether in medicine, industry, or education: the use cases for FlexiVol are diverse. Architecture firms can adjust building models in mid-air. Surgeons can explore virtual anatomy with their bare hands. XR designers can test holographic interfaces without wearing a device.
This technology also opens new possibilities in entertainment, gaming, and digital customer experiences: holographic avatars interacting with users. Product presentations with physical depth. Or real-time collaboration in immersive environments.

The Elastic Membrane as an Interface
The core of FlexiVol is its flexible membrane. It functions both as a projection and interaction surface. Through targeted vibrations and light control, it generates a three-dimensional image that is not only visible but also physically penetrable. The result is a perception of depth, volume, and materiality – created purely within a light field.
Tactile feedback is achieved through the physical deformation of the membrane. This deformation provides gesture recognition data and adjusts the light representation in real time.

The following graphic shows the main components of the system and the interaction with the projected light field. Especially striking: the interplay between real movement and virtual representation.

Performance and Study Results
User tests show: interacting with FlexiVol feels significantly more natural than with conventional XR devices. Studies by the HAL platform confirm that object selection and 3D tracing by hand are faster and more intuitive. Cognitive load is also measurably reduced.
Particularly relevant: tactile feedback enhances spatial orientation and memory of virtual structures.
