Haptic hologram

Abstract

In a first aspect, the invention relates to a system for generating a haptic perception and a holographic image. The system comprises a light source for emitting light and a main body comprising a substrate and at least one holographic optical element. The light source and the main body comprising the holographic optical element are designed to generate a holographic image in an interaction region. At the same time, the system comprises one or more sound transducers for emitting sound waves in the direction of the interaction region such that pressure fluctuations are haptically palpable within the interaction region. The system is characterized in that the substrate is situated between the one sound transducer or the plurality of sound transducers and the interaction region and comprises sound channels, formed as openings, through which the sound can propagate. In a further aspect, the invention relates to the use of the system according to the invention for generating a holographic image and a haptic perception.
