Improving User Experience of Assistive Technology Through Codesign and 3D Printing: A Case Study from Cancer Treatments

Abstract

Stigmatization negatively affects the quality of life of people living with cancers or chronic diseases. This issue often arises from the use of assistive technology and medical devices during daily activities. These products may create barriers within the social context rather than encourage inclusiveness. This work aims to investigate the role of codesign and digital technologies, i.e., 3D printing, in improving the user experience of assistive technology. The focus is to reduce or eliminate the stigma-related issues and improve the quality of life through codesigned customizable assistive products. A codesign process was carried out within the case study of "B.EAUTYlities", a project focused on the daily life needs of people with cancers or chronic diseases. The design experimentation resulted in the development of two customizable products to manage a central venous catheter for cancer treatments during the user's daily routine, i.e., protecting the catheter during outdoor activities or showers. Two online open-source configurators were developed to allow users to customize their device and manufacture it with low-cost 3D printing processes. Stigmarelated issues can be mitigated thanks to the users' active role during the codesign process since their perception and feedback can be considered a key aspect to design new assistive products. Digital technologies and customization can spread accessible assistive technology, as well as open-source principles and distributed manufacturing networks. The user experience may be positively affected not only by the efficacy of these products in fulfilling their primary function but also by their customization, strengthening the emotional attachment to the products.
