“…Cameras, which are the sensors, capture the patient's movement, and the motion of those markers can be tracked and analyzed. Examples come from the assessment of the amount and the consistency of natural motion at the trunk anatomical complex during locomotion and elementary oscillatory exercises (Benedetti, Biagi et al, 2011), biomechanical analysis in posture & gait (D'Amico et al, 2011), head-tracker device based on a light source placed on the patient's head and a CCD camera which capture the movements of the head (Lin et al, 2006), and so on.…”

Every day, all around the world, millions of people request postural and/or motor rehabilitation. The rehabilitation process, also known as Tertiary Prevention, intends to be a sort of therapy to restore functionality and self-sufficiency of the patient, and regards not only millions of patients daily, but involves also a huge number of professionals in medical staffs, i.e. specialists, nurses, physiotherapists and therapists, social workers, psychologists, physiatrists. The care is given in hospitals, clinics, geriatric facilities, and with territorial home care. For the large number of patients as well as the medical staff and facilities necessary to support the appropriate postural and motor training, the monetary costs of rehabilitation is so large, it is difficult to estimate. So, every effort towards a simplification of the rehabilitation route is desirable and welcome, and this chapter covers this aspect.

“…Certain interfaces automatically recognize regions of the head by means of a webcam-type camera. Others recognize objects attached to the user’s head, such as small colorful targets 4 , 5 , 9 , 12 or reflective targets such as the Tracker Pro (Madentec ® Ltd, Edmond, AB, Canada), HeadMouse Extreme ® (Origin Instruments Corporation ® , Grand Prairie, Texas, USA), and SmartNav ® devices (Natural Point ® Inc., Oregon, USA).…”

OBJECTIVESThe objectives of this study were to develop a pointing device controlled by head movement that had the same functions as a conventional mouse and to evaluate the performance of the proposed device when operated by quadriplegic users.METHODSTen individuals with cervical spinal cord injury participated in functional evaluations of the developed pointing device. The device consisted of a video camera, computer software, and a target attached to the front part of a cap, which was placed on the user’s head. The software captured images of the target coming from the video camera and processed them with the aim of determining the displacement from the center of the target and correlating this with the movement of the computer cursor. Evaluation of the interaction between each user and the proposed device was carried out using 24 multidirectional tests with two degrees of difficulty.RESULTSAccording to the parameters of mean throughput and movement time, no statistically significant differences were observed between the repetitions of the tests for either of the studied levels of difficulty.CONCLUSIONSThe developed pointing device adequately emulates the movement functions of the computer cursor. It is easy to use and can be learned quickly when operated by quadriplegic individuals.
