Virtual System for Upper Limbs Rehabilitation in Children

A virtual system is presented for upper limbs rehabilitation in children using a haptic device and oculus rift. Two interactive games were created in Unity 3D with daily tasks and easy execution. In addition, the virtual system was used by two groups of children (CP and Down Syndrome) with mild spasticity, the same ones who performed the exercise. The movements allowed by the system help in the rehabilitation of the hands and in hand-eye coordination. The participants completed a SEQ usability test with results (52 ± 0.43) by group 1 and (53,5 ± 0,72) by group 2. The outcomes allow determining that the system has a good acceptance to be used in rehabilitation. Children in group 2 (Down Syndrome) achieved to manage the system successfully despite intellectual and ocular difficulties.

VRAndroid System Based on Cognitive Therapeutic Exercises for Stroke Patients.

It is presented VRAndroid System designed in Android and implemented on an Android Tablet, the system consists in a set of nine shapes based on cognitive therapeutic exercises for the motor rehabilitation in upper limbs, this tools provides perceptive feedback (vibration) to the patient as he follows the correct shape with his finger. There are two performed rehabilitation phases: (1) Through the Perffeti Technique (15 sessions), (2) Through VRAndroid System (15 sessions), the evolution and results of the rehabilitation are evaluated by the BOX AND BLOCK test, which shows that, the rehabilitation through this techniques help in the motor recovery of the upper limbs, moreover, the VRAndroid System is a useful tool to be used as a traditional rehabilitation supplement.

Fuzzy control implementation in low cost CPPS devices

In the present day, industry has been brought closer to the Industry 4.0 paradigm due to its needs of reaching better industrial communications and improving the control process. According to the IIoT concepts, Cyber Physical Production Systems (CPPS) are normally connected to each other, and also connected to the virtual world of global digital networks. By introducing the IEC-61499 standard, CPPS will be allowed to implement flexible, reconfigurable, and distributed controllers. Fuzzy controllers are an advanced control solution that adds certain level of human reasoning to the system, making it possible to obtain a suitable alternative for traditional controllers. Due to the requirement of IEC-61499 of using as controller device an embedded platform, the encapsulation of advanced techniques of control in the algorithms of a systems becomes more simple and efficient. This is why it is necessary to provide the industry with low-cost alternatives who can easily integrate more complex and efficient controllers, making it possible to redirect the CPPS development to a new variety of devices. This paper proposes the development of the Function Blocks (FBs) needed in order to create a distributed control system based on Fuzzy Logic to control an analog process.

Construction and analysis of PID, fuzzy and predictive controllers in flow system

This paper presents the construction of a flow station that allows the implementation of different advanced control technique. Furthermore this work focuses on comparing of the performance of traditional PID controllers, Fuzzy logic and predictive MPC when controlling the flow dynamic variable and to analyze the advantages and disadvantages of these control strategies in industrial processes. The characteristics of the controllers are tested both in simulation and experimentation with dedicated software in systems analysis.

3D Virtual System for Strengthening Lower and Upper Limbs in Children

A virtual system is presented for child limb strengthening by using the Kinect device. An interactive environment was created using Unity 3D in order to perform movements with upper and lower limbs. The system was tested by one user, the same one performed every exercise correctly, and this helped to strengthen the affected area. Additionally, graphs were generated to compare therapist movements as an input signal versus user movements as an output signal.

Fine Motor Rehabilitation of Children Using the Leap Motion Device – Preliminary Usability Tests

A 3D virtual system is presented using the leap motion device and Unity 3D software. The system is based on three playful tasks that allow children to recover their fine motor skills in an entertaining way. This system is designed to perform movements like flexion-extension of fingers, supination-pronation, ulnar and radial deviation. The games stimulate visual motor coordination and concentration, which are important factors in the recovery of fine motor skills. The system was used by ten children aged between 6 and 10 years and they have the support of a rehabilitation specialist. After they have completed all the tasks, the SEQ (Single Ease Question) usability test was applied with results (60.8 ± 0.26). The test allows determining that the system has a good acceptance to be used in rehabilitation.

3D Virtual System Based on Cycling Tracks for Increasing Leg Strength in Children

A 3D virtual system based on cycling tracks is presented. The virtual environment is developed in Unity 3D. Two games are created with different levels of difficulty. The system is created for improving strength, resistance and muscle activation in children. Operation tests and usability are performed in four children between 5 and 9 years old. After the usability surveys SEQ, the outcomes (54.5 ± 0.34) shows that users feel immersed and enjoy the game. The system motivates the user to continue using it.

Interactive System for Monitoring and Control of a Flow Station Using LabVIEW

This work delivers the design of an interactive system that allows end user to interact with an intuitive, friendly and efficient way within the process control world. Using Raspberry Pi 3 with a high-level language, a fuzzy control algorithm applied to a flow station is implemented, whose information will be sent in serial form to an interface developed in the LabVIEW software. This interface has three windows, in which you can modify the value of the setpoint, trends views and save historical data for the subsequent processing of such information. This will replace the expensive conventional display screens, with interfaces developed in computer. Besides, it is demonstrated its applicability and ease of communication with low-cost embedded boards, through experimental tests and usability surveys.

Interactive System Using Beaglebone Black with LINUX Debian for Its Application in Industrial Processes

In this article it presents the development of an interactive system, which allows the user to interact with an air flow temperature control process, implemented with two control algorithms: Proportional Integral Derivative PID and Fuzzy control. It is intended to demonstrate the usefulness of an interactive system in industrial applications, it is used a low-cost embedded system the Beaglebone Black and LINUX Debian free software, also the system allows to enter the desired control parameters and to adequately observe the behavior of the process and the efficiency of the controller; for the verification of the interactive system, a model of air flow temperature control plant was constructed, which is currently used as a didactic module in the Laboratory of Process Control of the University.

Interactive System for Hands and Wrist Rehabilitation

An Interactive system is presented for the rehabilitation of hands and wrists using the leap motion device and the Unity3D software. Two applications were created with several movements were by programming such as flexion, wrist extension, pronation, supination and adduction. Through the interfaces the users have immersion and perform the exercises correctly because at the end of the game a visual and audible feedback is presented. Five people used the system and then the SEQ usability test was applied with results of 59.6. This indicates that the system has a good acceptance and can be used for rehabilitation.
