SUMMARY:

This work aimed to develop a real-time test platform for systems associated with the tactile internet area. The proposal comprises a master device, a communication channel and a slave device. The master device is a tactile glove (wearable technology) that works as a tactile interface based on vibratory feedback, responsible for enabling interaction with virtual or remote elements. Additionally, the communication channel introduces a bidirectional connection of variable latency. In turn, the default slave device is a robotic Phantom Omni manipulator integrated with the Matlab/Simulink environment and the robotics toolbox. The platform can generate tactile sensations such as coarse roughness, fine roughness, smoothness, dripping and softness. Furthermore, the results of the proposal have been adequate and allow testing various algorithms and methods related to tactile internet.  Therefore, the developed system has the capacity to serve as a basis for a wide variety of use cases related to tactile internet, providing a diverse opportunity for exploration and application. In this sense, the proposed platform serves as a foundation for a use case focused on tactile exploration of product textures on an e-commerce website, enabling interaction with virtual clothing through online shopping capable of providing tactile stimuli. In the scenario of this use case, the slave device is a cursor that functions as an element controlled by the master device and a mouse, which allows interaction with different clothing textures, generating specific tactile sensations on the tactile glove. In order to enhance the platform performance, Virtual Network Functions (VNFs) were introduced. VNFs are virtualized processes implemented and executed in cloud services, capable of enhancing the scalability and agility of a network, while also enabling more efficient utilization of infrastructure resources. In Fifth Generation (5G) mobile networks, tactile internet connections are associated with ultra-reliable low-latency communications (URLLC) services. This category poses challenges due to its stringent requirements of low latency in a few milliseconds, low packet loss probability, and high network availability. Thus, the application of VNFs during tactile internet connections in 5G networks allows for adjustments of connection parameters to maintain good connectivity, ensuring the low-latency criterion and a high degree of realism in tactile interactions. Consequently, the use of VNFs in URLLC communications aims to fulfill the requirements of tactile internet systems while maintaining an acceptable level of Quality of Experience (QoE), which is a metric defined by the Telecommunication Standardization Sector as the degree of satisfaction or annoyance of users with an application or service.
