Vibrotactile feedback for the accessibility of DAWs for Blind and Visual Impaired Music Creators

Haptic technology presents promising avenues for enhancing the usability of computer interfaces, offering supplementary modes of communication and interaction. This research explores the use of vibrotactile feedback for the accessibility of music production software for visually impaired users. The Digital Audio Workstation (DAW) interface is derived from analogue audio-visual interactions that subsequently impose substantial limitations for visually impaired users. The use of screen readers, in addition to the audio feedback, limits considerably the functionality of the software.

This study explores the role of tactile feedback in making music production accessible for blind and visually impaired (BVI) individuals by using participatory design methods. Interviews with BVI music producers worldwide provide insights on the way they use of external music hardware devices. These devices are currently providing tactile feedback to create a more efficient workflow. These interviews helped identify additional forms of haptic feedback that could further enhance users' workflows.

Building on these insights, we designed and developed a wearable wristband that offers vibrotactile (vibration-based) feedback as an alternative means of communicating with on-screen UI elements. Follow-up interviews and user testing revealed that participants found vibrotactile feedback enjoyable and beneficial. Through iterative testing and user feedback, the technology was refined into a flexible tool, enabling users to integrate vibrotactile feedback seamlessly into their interactions with the DAWs.

Project Aims:

  • Understanding the role of tactile interaction and music hardware devices in accessibility of music production for blind and visually impaired users. 
  • Promote inclusive and participatory design techniques for improving the accessibility of DAW.  
  • Examine the use of vibrotactile feedback for interacting with UI elements in DAW for non-visual interaction.

Project Impacts:

In the field of HCI, very few researchers have explored how to make music creation accessible for blind or visually impaired people. This project stands out by demonstrating the benefits of using haptic feedback in music production. It also provides a practical design strategy for developing a new tool that incorporates vibrotactile feedback in the DAW interaction.  

The goal of this project is to make music production more accessible by involving blind and visually impaired musicians directly in the design process. From the start, we worked closely with these musicians, using their feedback to shape the project at every stage. This ongoing collaboration helped open-up new ideas for improving accessibility in ways the participants had not experienced before. 

Beyond the immediate impact on the musicians involved, the project promotes greater equality in music, whether as a hobby or a profession. It also opens-up more job opportunities in the creative industry for people with visual impairments. By focusing on music production, the research provides valuable insights into how different types of interaction—especially touch—can improve accessibility and make design more inclusive overall.
