• Shared control algorithms and advanced sensing modalities were integrated into the wheelchair designs.
• Extensive experimental validation confirmed the potential of these systems to improve user quality of life.

Research Evidence

Aim: How can co-design and modularity in robotic assistive technologies for smart wheelchairs improve users' quality of life?

Method: Co-design, Experimental Validation

Procedure: The research involved identifying clinical needs with medical partners, developing two novel smart wheelchairs with complementary capabilities, and creating a virtual reality (VR)-based wheelchair simulator. These systems were then validated through extensive experimental campaigns.

Context: Assistive robotic technologies for electric wheelchairs.

Design Principle

User-centered design with modularity and shared control enhances the efficacy and adoption of assistive technologies.

How to Apply

When designing assistive devices, conduct thorough user research and consider a modular architecture that allows for adaptation to individual needs and technological advancements.

Limitations

The study was conducted within the framework of a specific EU project, and the generalizability of findings to all wheelchair users and contexts may require further investigation.

Student Guide (IB Design Technology)

Simple Explanation: When designing things like wheelchairs for people with disabilities, it's super important to ask them what they need and build the product in a way that can be easily changed or updated later. This makes the product much more helpful and improves their lives.

Why This Matters: This research shows that involving users and making designs flexible are key to creating products that genuinely help people and improve their daily lives, especially in assistive technology.

Critical Thinking: To what extent can the success of this co-designed modular approach be replicated in other assistive technology domains with different user groups and technological constraints?

IA-Ready Paragraph: This research by Morbidi et al. (2022) underscores the significant impact of user-centered design and modularity in developing assistive technologies. Their work on smart wheelchairs, which involved close collaboration with users and medical partners, highlights how co-design and adaptable systems can substantially improve the quality of life for individuals with mobility impairments. This principle is directly applicable to my design project, emphasizing the need for thorough user research and a flexible design approach to ensure the final product effectively meets user needs.
