Summary: This study explored the understanding and attitudes of patients who underwent knee replacement surgery regarding AI in the context of risk prediction for shared clinical decision-making. The study found that patients had varied levels of familiarity with AI and diverse conceptualizations of its definitions and capabilities. The study suggests that educating patients about AI through non-technical explanations and illustrative scenarios could help inform their decision to use it in the shared decision-making process with their surgeon.

Summary: A Human-Prosthetic Interface (HPI) is used to estimate and implement the desired limb pose by the user through sensors worn on the body. Unlike conventional methods, which map each degree of freedom to one or a pair of sensors, recent studies have shown that HPI can map multi-joint limb poses to multiple sensors. This approach requires systematic sensor selection to optimize system accuracy and minimize the complexity of the prosthetic system. This paper proposes an algorithm called Sensor Selection with Composite Features (SS-CF) to solve the sensor selection problem.
