In this study, an innovative transfer aid is proposed to respond to home care needs of ageing society. The fact that long-term care demanders nowadays prefer to live with their families and friends indirectly results in the gradually increasing number of non-professional caregivers. The incidence of work related injuries of amateur caregivers will be higher than professional nurses. Among all of the nursing activities, patient handling (PH) is the most frequently reported injuries. It is not uncommon to see even the professional nurses getting hurt from transferring patients, not to mention the non-trained caregivers. One of the reasons is that they are not familiar with transfer aids, such as when and how to operate proper aids. Accordingly, the operation of transfer aids for patient handling during home care must be reconsidered and redesigned. Activity theory and Contextual design were adopted in this paper to redesign the caregiver centered transfer aid.
