Many people with disabilities, especially those with physical disabilities, could work, draw or produce art. However, very few workstations and tools are developed to meet their needs and conditions. The objective of this study is to evaluate the needs of an artist with a disability for an ergonomic workstation and to propose a prototype that increases the comfort and capabilities of people with physical disabilities to perform their tasks. First, we analyzed the tasks/activities, postures, and needs of an artist with a high level of disability while performing his drawing tasks in a real-life situation. Second, we simulated an art studio with the participation of six non-artist subjects with motor and mental disabilities to evaluate the user's experience and difficulties when painting in a similar real situation. Based on these studies, we proposed a specification for the design and prototyping of a painting workstation adapted for people with disabilities.Our analysis showed that very few workstations are adapted for people with disabilities and they must work on the floor with awkward postures, insufficient lighting and limited space. They have to make excessive efforts to perform most of their activities because the tools and workstations do not meet their needs. Based on the specifications extracted from our study, we propose a new design of painting workstation dedicated to disabled people to improve their comfort and performance.

For Aristotelian scholars, matter is identified as the subject of change, while form is the boundary of matter. Design is a process of bringing about change. From a design perspective, material is what an entity is made from; form is what makes a thing what it is. Based on the principle, “form is the boundary of matter”, this paper proposes a Design by Material method, thereby addressing the knowledge gap of a systematic method for designing according to material. This method is predicated on the material specification as the first input in the design process. A formal model is built in which the material acts as a trigger and driver for the design process. The method is implemented by integrating computer-aided design (CAD) modelling and its design form. A design application is explained to demonstrate the relevance of the Design by Material method.
