Objective: To explore the accuracy, safety and clinical effect of descending thoracic pedicle screw fixation assisted by computer CT three-dimensional navigation in the treatment of single segmental compression thoracic fracture.Methods: This study was a ... see more

Autonomous underwater vehicles (AUVs) are widely used and have proven their effectiveness in tasks such as transportation safety, area monitoring and seafloor mapping. When developing AUV’s navigation and control systems, the engineers have to ensure the ... see more

This paper analyses the acceptance of a smartphone navigation app in a hospital among its patients/visitors. We tested the effects of socio-demographic factors (gender, age, and education) on technology acceptance and on perceived difficulties with wayfin... see more

People with visual impairment face enormous difficulties in terms of their mobility as they do not have enough information about their location and orientation with respect to traffic and obstacles on their route. Visually impaired people can navigate unk... see more

Two of the common problems associated with navigation research in the field of human computer interaction (HCI) systems, are the relatively narrow view that the display is able to provide for a large information space, and the impact that a diversity of c... see more

The PN-guidance (Proportional Guidance) still continues to be improved, because it is the simplest, cheapest and most reliable algorithm. One of the most important techniques to improve PN-guidance is to adapt the navigation constant depending on time. In... see more

The purpose of this study was to evaluate intraoperative alignment during total knee arthroplasty using a handheldnavigation system, iAssist, in comparison with conventional optical surgical navigatio... see more

Whenever People visit some places like hospitals, museums, and colleges they find difficult to navigate to a particular location. Using GPS for indoor navigation is not possible because GPS-enabled smartphones have accuracy within a 4.9 m (16 ft.) radius ... see more

In this paper, the potentials of using Global Navigation Satellite System (GNSS) techniques in the complex calibration procedure of the tracking sensors for missile test range applications have been presented. The frequently used tracking sensors in test ... see more
