Background
Unsafe surgical care has emerged as a significant public health concern, motivated by a high percentage of major complications happening during surgery, attributed to surgeons' skills and experience, and determined to be preventable.
Methods
This article presents APSurg, an Abdominal Positioning Surgical system designed to improve awareness and safety during laparoscopic surgery. The...
Hyperarousal is a critical component of insomnia, particularly at bedtime when individuals are trying to fall asleep. The current study evaluated the effect of a novel, acute behavioral experimental manipulation (combined immersive audio-visual relaxation and biofeedback) in reducing bedtime physiological hyperarousal in women with insomnia symptoms. After a clinical/adaptation polysomnographic (PSG)...
Error-related electroencephalographic (EEG) potentials (ErrPs) have been explored to improve the reliability of modern Brain-Computer Interfaces (BCIs), thanks to the information they carry about user awareness of erroneous responses. ErrPs detection on a single-trial basis has been successfully demonstrated, and proved to effectively enhance human-computer interaction and BCI performance. Previous...
Eye-tracking (ET) is one of the most intuitive solutions for enabling people with severe motor impairments to control devices. Nevertheless, even such an effective assistive solution can detrimentally affect user experience during demanding tasks because of, for instance, the user's mental workload - using gaze-based controls for an extensive period of time can generate fatigue and cause frustration...
This paper presents a master-slave configuration robotic microsurgical forceps, which is capable of performing micro tissue manipulation. The master, i.e., 7 degree of freedom (DOF) device (Sigma.7), tele-operates the slave device which is a combination of a 6-DOF serial robotic arm and a 1-DOF (open/close) microsurgical forceps device. The serial robotic arm is used for positioning and orienting...
Robotic systems offer the possibility of improving the life quality of people with severe motor disabilities, enhancing the individual's degree of independence and interaction with the external environment. In this direction, the operator's residual functions must be exploited for the control of the robot movements and the underlying dynamic interaction through intuitive and effective human-robot...
In past decades, eye-tracking (ET) became one of the most widespread communication strategies for people with severe motor impairments (as in locked-in syndromes, LIS). ET cameras enable paralyzed patients to move a cursor across a user interface (UI) by means of their gaze, and to activate a selectable UI object after looking at it for a certain dwell time. This procedure is definitely intuitive...
Transoral Laser Microsurgeries (TLM) demand a great level of control and precision in intraoperative tissue manipulation. The optimal eradication of the diseased tissue is possible only with coordinated control of the laser aiming for incision and the microsurgical tools for orienting and stretching the tissue. However, the traditional microsurgical tools are long, single purpose, one degree-of-freedom...
Brain-computer interfaces (BCIs) offer high potential for enhancing training in many tasks, especially those that require maintaining high levels of concentration such as surgery. Training focus and attention can play a critical role in surgery since concentration on the task at hand is fundamental to prevent life-threatening errors. In this paper we propose a new method for concentration training...
Human error is a critical risk in surgery, so an important aim of surgical robotic systems is to improve the performance and the safety of surgical operations. Such systems can be potentially enhanced by a brain-computer interface (BCI) able to monitor the user's mental focus and use this information to improve the level of safety of the procedures. In order to evaluate such potential usage of BCIs,...
Several studies showed the potential of interaction technologies for assisting the performance of users during motor tasks. In particular, repetitive exercises can take advantage of novel interaction strategies in order to sustain the users efforts to maintain the target level of performance. This paper introduces a paradigm for performing a drag and drop movement of Augmented Reality 3D objects from...
Robot-assisted surgical procedures, such as Laser Phonomicrosurgery (LP), suffer from susceptibility to variation in surgeon skill and equipment characteristics. Ergonomic and human-centered approaches acquire increased importance in the design of surgeon-machine interfaces. This paper proposes a protocol for comparative evaluation of surgeon-machine interfaces based on two criteria: (i) the subjective...
Innovative design features of user interfaces could assist a patient during the accomplishment of repetitive physical exercises in training and rehabilitation. Dual task paradigms can induce a change in attentional focus allocation, moving focus away from a body part which is affected by fatigue. This study proposes an interface which integrates the motion tracking capabilities of a Kinect with the...
State-of-the-art laser phonomicrosurgery (LP) used for the treatment of laryngeal abnormalities involves complex otolaryngological surgical techniques. It relies heavily on surgeon dexterity, requiring significant psychomotor skills. Equipment scale and size, laser operative distance, and the anatomically small nature of the vocal folds all combine to compound the surgical challenges. An objective...
