Ultrasonic Mid-air Haptics (UMH) is a novel technology that uses the mechanical properties of sound waves to create a pressure point in mid-air. This pressure point, called focal point, can slightly bend the skin and be felt in mid-air without any attachment to the body. This thesis focuses on both studying how to integrate this technology with other senses (i.e. vision and audition) and exploring the range of tactile sensations it can provide.

The first two projects presented in this document present the integration of ultrasonic mid-air haptics with audio-visual content. The first project describes the process of creating a unique haptic experience that was part of a six-weeks multisensory exhibition in a museum. The second project moved from the museum to a controlled environment and explored the creation of haptic experiences based on physiologic measurements for six short films. Both studies showed the positive value of adding ultrasonic mid-air haptics to traditional media through higher reported arousal and participants’ high enthusiasm for multisensory content.

In the two latter projects of this thesis, it was explored how we could extend the range of possible tactile sensations provided by UMHs. We introduced a new technique called Spatio-Temporal Modulation (STM). It enabled the creation of brand-new tactile experiences, including more salient shapes and wider range of textures. We also provided some guidelines on how to control some of the tactile properties of the sensation, including strength,roughness,or regularity.

The findings of those four projects contribute to the growing body of knowledge of UMHs. A summary of the key contributions is provided at the end of the thesis as well as several leads for future works.
