Conversational AI combines natural language processing (NLP) with machine and deep learning models so that people can interact in human-like manner the digital devices. The quality of social interactions be additionally improved by utilizing physical presence robot prompting context derived from robot's hardware. Therefore, we propose a modular software architecture to integrate into Socially Assistive Robots (SARs). It follows flow-based approach shared repositories direct or message-based...
Human-like interactions with robots based on Conversational AI facilitate assistance and teamwork in various contexts. Those are further enhanced by utilizing physical presence context from the robot's hardware. Robot cooperation is also especially useful, when software or hardware resources have to be shared a multi-robot system. Therefore, we propose modular architecture for that extends integration of into Socially Assistive Robots, previously suggested authors. It utilizes flow-based...
This research aims to improve the pedagogical rehabilitation of children with Special Educational Needs (SEN) based on play-like activities for orientation in space, shapes, colors and emotions.

Our interest is in time series classification regarding cyber–physical systems (CPSs) with emphasis human-robot interaction. We propose an extension of the k nearest neighbor (kNN) classifier to time-series using intervals’ numbers (INs). More specifically, we partition a into windows equal length and from each window data induce distribution which represented by IN. This preserves dimension representation. All-order statistics, IN, are employed implicitly as features; moreover, parametric...
Humanoid robots have a substantial potential to serve as teaching and social assistants. However, the expectations of children from interact like humans are huge.

Thus, physical presence robot can help fine-tuning GPT prompts derived environmental context subsequent actions embodiment outputs. The uses web or...
P300 is one of the most widely studied event-related potentials. Unfortunately, existing automatic detection schemes require computations over repetitive trials in both training and recognition phases. Several attempts have recently been endeavored towards single trial signals. However, no acceptable solution to problem found till date. In present work, we attempted address this light latency (amplitude) deflection signal. The intra- inter-personal variations inherent these features are...
The paper presents a "design and simulation of gesture"-based model to support education children with hearing problems. To engage the child's attention control their own learning according individual skills, framework is proposed for interaction an artificial hand in form game rewards correct answers. anthropomorphic hand, designed purpose 3D, both realistic able produce all fingerspelling signs international sign language. novelty present work integration biologically feasible movements...
Social robots keep proliferating. A critical challenge remains their sensible interaction with humans, especially in real world applications. Hence, computing semantics is instrumental. Recently, the Lattice Computing (LC) paradigm has been proposed a capacity to compute represented by partial order mathematical lattice data domain. In aforementioned context, this work proposes parametric LC classifier, namely Granule-based-Classifier (GbC), applicable (T,⊑) of tree structures, each which...

It can wire assistive devices, APIs, online agents meet child individual needs intervention. Humanoid NAO-type robot, Emotiv EPOC+ brain headset, emotionally-expressive robot EmoSan Kinect depth sensor...
Robots of the future will socialize with humans. Human-robot interaction (HRI) by a vision-based gesture interface helps to personalize communication humans in various contexts - from support their daily life social skills training children developmental problems. We are especially interested hand HRI and propose recognition system based on novel online extraction classification scheme, which is lightweight can be used mobile robot. An Lightweight Evolving Fuzzy Clustering Method categorize...
Abstract The paper presents enhancements and innovative solutions of the proposed in [3] algorithms for fingers tracking hand gesture recognition based on new defined features describing gestures exploiting new-tracked tip thumb joints from Kinect v2 sensor.
