Usability, comfort and acceptance of such devices will affect their uptakes in mainstream daily life. The XoSoft EU project developed a modular soft lower-limb exoskeleton to assist people with low mobility impairments. This paper presents the bio-inspired design of a soft, modular exoskeleton for lower limb assistance based on pneumatic quasi-passive actuation. The design of a modular reconfigurable prototype and its performance are presented. This actuation centers on an active mechanical element to modulate the assistance generated by a traditional passive component, in this case an elastic belt. This study assesses the feasibility of this type of assistive device by evaluating the energetic outcomes on a healthy subject during a walking task. Human-exoskeleton interaction in relation to task-based biological power assistance and kinematics variations of the gait are evaluated. The resultant assistance, in terms of overall power ratio (Λ) between the exoskeleton and the assisted joint, was 26.6% for hip actuation, 9.3% for the knee and 12.6% for the ankle. The released maximum power supplied on each articulation, was 113.6% for the hip, 93.2% for the knee, and 150.8% for the ankle.

Abundant HCI research exists on the many assistive technologies that provide help with everyday physical and cognitive tasks. However, while a purely assistive approach often casts aging people in passive roles, recent studies suggest that adults may be ‘flourishing’ way into advanced age, even though implicit ageist prejudices are difficult to eradicate. Negative age-related stereotypes are the hidden and yet urgent issue we address in this study. There is a clear opportunity for an anti-ageist perspective in HCI, an approach that we propose as complementary to assistive technologies: in addition to providing solutions for the aging population, we urgently call for designs about aging, to spark a conversation on age, raise awareness and ultimately contrast ageist stereotypes. We point at empathy as a key element to reconceptualize, at least in part, HCI’s contribution to research on aging. We present a design critique of two interactive pieces that, although not without flaws, suggest how future empathy-raising artifacts might be. Our analysis combines pragmatist aesthetics, interaction criticism and ludology, and yields four design tactics (recurring configurations of significant elements) that are generative in bringing about broader design implications towards a different, empathy-based concept of aging in HCI.
Abstract: Background: There has been a rapid increase in the population of senior citizens in many countries. The shortage of caregivers is becoming a pressing concern. Robots are being deployed in an attempt to fill this gap and reduce the workload of caregivers. This study explores how healthcare robots are perceived by trainee care professionals. Methods: A total of 2365 students at different vocational levels completed a questionnaire, rating ethical statements regarding beneficence, maleficence, justice, autonomy, utility, and use intentions with regard to three different types of robots (assistive, monitoring, and companion) along with six control variables: gender, age, school year, technical skills, interest in technology, and enjoying working with computers.
