A New Control Approach for a Multi-Controlled Wheelchair Utilizing Deep Learning Framework and Raspberry Pi
Sudipta Chatterjee, Angshuman Majumdar, Sahadev Roy
IETE Journal of Research, 2025
This article describes the construction and control mechanisms of a multiple control wheelchair (MCW) aimed to aid individuals with amyotrophic lateral sclerosis (ALS) and lower limb disabilities. The MCW has been tested in the laboratory on a total of 10 patients, among them 3 with lower limb disabilities, 6 elderly patients, and 1 patient with ALS. The proposed wheelchair can navigate in any direction using object detection techniques powered by OpenCV. Employing a deep learning algorithm, it performs real-time object detection and tracks its current position in various environmental conditions. The MCW can be controlled using a joystick, internet of things (IoT), or a combination of both. A novel aspect of this work is the implementation of a deep learning framework on a Raspberry Pi processor, allowing the wheelchair to navigate in any direction based on the user’s needs. The Raspberry Pi interfaces with all sensors, camera, and additional peripherals through serial communication, enabling monitoring and control via an android mobile application. This setup effectively reduces the physical distance between the user and the caregiver. During the test, a range of functional measurements were taken, including assessments of the object detection process and the performance of hardware components such as sensors and motors connected to the system. The current system is unable to precisely determine an object’s position during detection, but ongoing research is focused on enhancing the system’s capability to accurately map objects in 3D space for improved wheelchair navigation.
Comparison of 5G-IoT antenna performance by using four distinct dielectric materials to verify their efficiencies
Kaushal Mukherjee, Sahadev Roy
International Journal of Communication Systems, 2024
SummaryThe characterization of four different materials, Taconic (D1), FR4 (D2), Lab material (D3), and Created material (D4) using the ring resonator technique, is presented in this study along with a comparison of antenna performance using standard and measured dielectric constant () and loss tangent () values. This article discussed the comparison of antenna performances on four distinct dielectric materials to verify their efficiencies. Standard values of for the reported materials are 2.20, 4.40, 2.33, and 10.45 for D1, D2, D3, and D4, respectively, with corresponding values of 0.0009, 0.02, 0.0012, and 0.00032. The and for the materials D1, D2, D3, and D4 are calculated as 2.10, 4.56, 2.51, and 9.89 and 0.00094, 0.01927, 0.0013, and 0.0003025, respectively, using a ring resonator. The materials are utilized as the substrate for a printed single layer Y‐Shape 5G‐IoT antenna in order to validate the measured results. According to the findings of this study, the measurement of using the resonator approach exhibited errors of 4.54%, 3.63%, 7.82%, and 5.33%, respectively, while the has errors of 04.44%, 03.65%, 08.33%, and 5.47% for materials D1, D2, D3, and D4, respectively. The outcomes of this work include the numerical calculation of the and of four materials and the validation of the measured values using a Y‐Shape 5G‐IoT antenna in the millimeter‐wave 5G frequency bands. Additionally, the values calculated mathematically are compared with the values obtained from the conventional ring resonator.
Design and development of dynamic gesture recognition system based on deep neural network for driver assistive devices
Arindam Mondal, Sahadev Roy
International Journal of System of Systems Engineering, 2023
The field of human-computer cooperation is a significant heading in the Internet of Things innovation. Human-Computer cooperation through signals is the bearing of nonstop examination of Internet of Things innovation. The Kinect sensor should be additionally enhanced to acknowledge complex motion developments, particularly the issue that the acknowledgment pace of dynamic signals is not high, which upsets the improvement of human-computer association under the Internet of Things innovation. In work presented in this paper, the Kinect-based motion acknowledgment is investigated exhaustively, and a unique motion acknowledgment strategy dependent on hidden Markov model (HMM) and dynamic-Signal evidence hypothesis is proposed. Based on the first HMM, the digression point and signal change at various snapshots of the palm direction are utilised as the qualities of the perplexing movement motion, and the quantity of quantisation codes diminishes the element of the direction digression.
HAZARD PERCEPTION TEST AMONG YOUNG INEXPERIENCED DRIVERS AND RISK ANALYSIS WHILE DRIVING THROUGH A T-JUNCTION
Md Faysal Kabir, , Sahadev Roy, and
Decision Making Applications in Management and Engineering, 2023
: In this article, the hazard-based accident duration model and the reaction time due to various types of distractions are considered. This analysis is mainly considered T-junction or T-junctions like all other forms of road geometries which are more prone to accident. The model proposed is constructed by using a electronics devices along with driving simulator, to study the behavior of the yang inexperienced drivers as well as an experienced driver about their reaction by calling their phone from unknown numbers intentionally. The results show that drivers distracted by mobile phones uses the hard breaking due to least available time to respond after identification of an event. Some of the research and theory bearing on decision making and risk perception, driver situation awareness, and possible mediators of risk-taking is also analyzed here.
Design and development of fusion-based expert system for multimodal biometric recognition with facemask authentication
Arindam Mondal, Sahadev Roy
International Journal of System of Systems Engineering, 2023
A multimodal biometric system can be processed on more than one biometric feature and make the authentication process more impactful in comparison with the traditional identification system. Here in this paper, with the help of discrete cosine transformation (DCT), Hough transformation technique, and discrete wavelet transformation (DWT) we have designed a decision-level fusion-based authentication. In our proposed authentication model, the system will take the face, ear, and iris images individually and doing DCT, DWT, and Hough transformation, finally apply decision level fusion for the biometric features extraction. Our proposed system has more authentication capability due to iris authentication features, which cannot be easily tampered with. This experimental process clearly shows that the proposed multimodal systems have more efficiency, reliability, and are more robust than other existing biometric multimodal systems and are able to authenticate with or without wearing a surgical face mask, useful for hazardous and contaminated environments.
Development of an accident prediction model for freeways systems
Md Faysal Kabir, Sahadev Roy
International Journal of Critical Infrastructures, 2023
This paper presents a model using log-logistics accelerated failure time approach based on the traffic accident records collected in the Ministry of Road Transport and Highways, Government of India in 2018-2019. This research work provides a series of approaches for identifying different critical elements to model accident prediction and clearance timing in freeways systems. Specifically, the innovative solutions are aimed at not only developing a prediction model but also analysing severity indicators like property damage, number of injuries, fatalities, etc. At the process level, the models are concerned with different variables, which play vital roles in real-life scenarios. The proposed model also keeps track of different random variables and is able to forecast possible accidents that may save several lives. Under influence of those random keys, this analysis also provides few suggestive proposals to take necessary precautions to reduce accident impacts and enhance traffic safety and the accident management process.
