An open question for the biomechanical research community is accurate estimation of volume and mass each body segment human body, especially when indirect measurements are based on modeling. Traditional methods involve adoption anthropometric tables, which describe only average shape, or manual measurements, time-consuming depend operator. We propose a novel method acquisition 3D scan subject’s obtained using consumer-end RGB-D camera. The segments’ separation by combining skeleton BlazePose...
Time-of-flight cameras are widely adopted in a variety of indoor applications ranging from industrial object measurement to human activity recognition. However, the available products may differ terms quality acquired point cloud, and datasheet provided by constructors not be enough guide researchers choice perfect device for their application. Hence, this work details experimental procedure assess time-of-flight cameras' error sources that should considered when designing an application...

In rehabilitation settings that exploit Mixed Reality, a clinician risks losing empathy with the patient by being immersed in different worlds, either real and/or virtual. While perceives stimuli mixed real–virtual world, physician is only part. rehabilitation, this may cause impossibility for to intervene, skill assessment, difficulty evaluation. To overcome above limitation, we propose an innovative Augmented Reality (AR) framework and assessment clinical settings. Data acquired...
The paper proposes an improved method for calculating the position of a movable tag whose distance to (redundant) set fixed beacons is measured by some suitable physical principle (typically ultra wide band or ultrasound propagation). based on multilateration technique, where contribution each individual beacon weighed basis recurring, self-supported calibration measurement repeatability at given range. work outlines and its implementation, shows improvement in quality with respect results...
Any severe motor disability is a condition that limits the ability to interact with environment, even domestic one, caused by loss of control over one’s mobility. This work presents RoboEYE, power wheelchair designed allow users move easily and autonomously within their homes. To achieve this goal, an innovative, cost-effective user-friendly system was designed, in which non-invasive eye tracker, monitor, 3D camera represent some core elements. RoboEYE integrates functionalities from mobile...
<p class="Abstract">Nowadays, the importance of working in changing and unstructured environments such as logistics warehouses through cooperation between Automated Guided Vehicles (AGV) operator is increasingly demanded. The challenge addressed this article aims to solve two crucial functions autonomy: identification, tracking. These tasks are necessary enable an AGV follow selected along his path. This paper presents innovative, accurate, robust, autonomous, low-cost real-time...
The purpose of this study is to analyze the different kinds ex- proprioceptive visual cues on an Augmented Reality (AR) system during gait exercise, top understanding which provide best visualizations in stepping over obstacles. main problem for users understand position virtual objects relative themselves. Since exproprioception provides information about body relation environment, it has possibility yield positive effects with regards control and biomechanics AR system. This research was...
In this work, we propose a new method to re-identify the same individual among different people using RGB-D data. Each human signature is combination of soft biometric traits. particular, extract color-based descriptor and local feature through Monte Carlo-based algorithm taking into account uncertainty joints and, applied each descriptor, refines similarity match against spatiotemporal database that updates over time. We analyzed effects Carlo refinement in terms final maximum matching...
Nowadays, the interaction of new technologies with humans can offer many advantages. Some them be found in production environment, where human being retrieved a central role thanks to Augmented Reality (AR). This augment capabilities, compensating respective limitations and providing benefits terms overall system performances. paper reports implementation an AR for industrial grinding process helping operator, comlpy working tolerances, repeatability comparable that automatic system. An...
This paper aims to evaluate and compare the driving performances achieved with a power wheelchair using standard joystick versus novel gaze-based technology. The interface, called RoboEYE, involves paradigm of computer interaction that handles receipt information from an eye tracker, it as continuous input for navigation. A pool 36 subjects has tested both technologies in circuit designed considering Wheelchair Skill Test. experimental analysis involved evaluations specific metrics motion...
Recent technological developments and projects are now becoming more multidisciplinary. However, in designing augmented reality training support systems (ARTSS), researchers this field may already hold biases that lean towards the de facto standard of what constitutes good ARTSS. These not inherently harmful, but there exists risk these lead to answering demands goals intended end-user completely different specializations. To address risk, we suggest using Par-ticipatory Design (PD) as a...
