Abstract Computer-assisted orthopedic surgery (CAOS) and augmented reality provides guidance for surgical environments in minimally invasive procedures. However, the surgeon’s interaction with those systems has limitations, because the surgical environment must be kept sterile. Two touch-less interaction techniques were evaluated within this research work, a visionbased technique used by META® glasses and electromyography-based used by MYO® arm-band. The research aim was to establish the most appropriate one touch-less interaction technique to manipulate a CAOS system. Usability was evaluated through an experiment with 4 orthopedic surgeons and 47 undergraduate students, in a simulated setting. The results suggest that both techniques can be relevant and useful in a surgical environment. However, the MYO was more efficient and possibly more effective to perform the manipulation tasks than META. In addition, the MYO arm-band was perceived as further satisfactory compared to META glasses and shown an improved overall behaviour in the CAOS system manipulations tasks.

1 Introduction A computer-assisted orthopedic surgery (CAOS) system aims to improve the surgeon’s perception of the surgical environment and the procedure step by step. Conventional surgery requires abilities such as fine motor skills that can be improved with visual and tactile feedback. The computerassisted surgery systems offer improved visualization of anatomy and provide data and information relevant to the surgical procedure, as well as visual feedback to the surgeon. The augmented reality (AR) technology applied to the medical field, provides a visualization of a patient’s medical data, diagnostic imaging and anatomical structures, superposed and registered in the physical scene [5,33]. Inside the operating theater, AR represents multiple advantages, among which are: the ability to place the patient and required information in the same 3D environment, also provides the

surgeon with a diagnostic imaging visualization allowing for higher focus on the patient, an accurate hand-eye coordination„ further facilitate a consistent observation of real and virtual instruments and, most importantly, to have a clear view of the patient anatomical structures [1,35]. CAOS systems require interaction devices such as keyboard and mouse, and in some cases, touch screens for manipulating the navigation software. Usually, CAOS systems are located on the opposite side of the surgical table; therefore, an assi
