Computer Keyboard

A user’s posture at a computer workstation, especially wrist posture, is determined by the keyboard angle. Most commercially available computer keyboards have a built-in positive slope that requires the user to extend their wrist approximately 20° when typing. The purpose of this study is to find the negative keyboard angles that minimize wrist extension for both sitting and standing workstations. In this study, we compared upper limb working postures, including those of the wrist, elbow and shoulder, at 5 different keyboard angles between −16° and +6° in sitting and standing postures. Based on our results, we can conclude that the optimal range of keyboard slope is from −4° to −12° in sitting posture and −8° to −12° in the standing posture in terms of minimum wrist extension, typing performance, and user preference. We also propose a universal keyboard support design as an attachment to currently available keyboards.

Care Evaluation

Objective: The purpose of this study is to understand the nature and source of disruptions in an ambulance during the telemedicine-based caregiving process for stroke patients to enhance the ambulance design for supporting telemedicine-based care. Background: Telemedicine is emerging as an efficient approach to provide timely remote assessment of patients experiencing acute stroke in an ambulance. These consults are facilitated by connecting the patient and paramedic with a remotely located neurologist and nurse using cameras, audio systems, and computers. However, ambulances are typically retrofitted to support telemedicine-enabled care, and the placement of these systems inside the ambulance might lead to spatial challenges and disruptions during patient evaluation. Method: Video recordings of 13 simulated telemedicine-based stroke consults were coded and analyzed using an existing systems-based flow disruption (FD) taxonomy. For each observed disruption—the type, severity or impact, location in the ambulance, and equipment involved in the disruption were recorded. Results: Seat size, arrangement of assessment equipment, location of telemedicine equipment (computer workstation), and design of telemedicine camera were among the factors that impacted telemedicine-related disruptions. The left ambulance seat zone and head of the patient bed were more involved in environmental hazard–related disruptions, while the right zone of the ambulance was more prone to interruptions and communication-related disruptions. Conclusion: Adequate evaluation space for the paramedic, proper placement of evaluation equipment, and telemedicine computer location could facilitate the stroke care evaluation process and reduce FDs in the ambulance.
