Music therapy can make a valuable supplement to purely verbal psychotherapy, but its use is limited as patients often cannot play conventional musical instruments due to motor skill limitations. This can hinder the psychological recovery, where musical expression is essential. To address this, the Haptic Finger Tracker was developed, emerging from a project at the ligeti zentrum, Hamburg, a collaborative initiative where researchers and artists work on interdisciplinary projects. This paper describes a prototype that translates minimal finger movements into congruent sound and haptic sensations. Technically, the device uses flex sensors and an inertial measurement unit (IMU) to capture a range of small-scale finger movements. Using the Open Sound Control (OSC) protocol, these captured gestures are then translated to control musical elements such as pitch, volume and arpeggios. Simultaneously, a vibrotactile actuator provides haptic feedback aimed at enhancing the user’s sense of engagement and embodiment. The resulting portable prototype provides patients with a creative outlet, fostering self-efficacy. This work establishes a technical foundation for future neurorehabilitative tools that utilize multisensory feedback to improve patient outcomes.enhttps://creativecommons.org/licenses/by/3.0/gesture-based musical controlfinger trackingmultisensory interactionvibrotactile feedbackTechnology::616: DiseasesConference Paperhttps://icmc2026.ligeti-zentrum.de/proceedings/10.15480/882.18204
