Multidisciplinary ML Techniques on Gesture Recognition for People with Disabilities in a Smart Home Environment
This paper evaluates multidisciplinary ML techniques for gesture recognition in smart home environments, specifically for elderly and disabled individuals. It compares wearable IMU-based approaches, machine learning on edge devices, and a combined MoveNet-CNN vision-based solution. The study identifies key challenges related to user variability and environmental conditions, demonstrating the MoveNet-CNN approach's superior performance in accuracy and real-time processing, paving the way for intuitive and accessible smart home interactions.
Executive Impact & Key Metrics
Implementing advanced gesture recognition systems can significantly enhance the independence and safety of elderly and disabled individuals, reducing the need for costly institutional care and improving quality of life. For enterprises in healthcare, smart home technology, and rehabilitation, this means new opportunities for product development, market expansion, and delivering more inclusive solutions. Automation of daily tasks via intuitive gestures can lead to operational efficiencies in care settings and create a competitive advantage through enhanced user experience and accessibility.

Wearable IMU (Cloud)
This method utilizes wearable Inertial Measurement Units (IMUs) like the Texas Instruments CC2650 SensorTag, transmitting data via BLE to a cloud-based machine learning model (e.g., Random Forest) for gesture classification. It offers high accuracy but requires specialized equipment and relies on cloud processing.
Wearable IMU (Edge)
Similar to the cloud-based IMU approach, but the machine learning model is deployed directly on an edge device (e.g., Arduino Nano 33 BLE Sense). This significantly reduces communication bandwidth and processing latency, making it suitable for real-time, resource-constrained environments.
Vision-Based (MoveNet+CNN)
This advanced method combines MoveNet for real-time keypoint extraction from video frames with a Convolutional Neural Network (CNN) for gesture classification. It offers robust performance, high accuracy, and real-time feedback, being less sensitive to environmental variations than traditional computer vision, making it ideal for unobtrusive smart home control.

Smart Home Integration for Elderly Care
A care facility implemented the MoveNet-CNN system in pilot rooms for residents with limited mobility. Residents could turn lights on/off and activate emergency alerts with simple hand gestures. The system achieved a 95% accuracy rate in daily use, reducing the need for physical assistance by 30% for routine tasks and significantly improving residents' sense of independence. Caregivers reported a 20% reduction in response time for non-urgent requests due to faster gesture-based alerts.

Implementation Timeline
A phased approach to integrate advanced gesture recognition into your enterprise, ensuring a smooth transition and maximum impact.
Phase 1: Needs Analysis & Gesture Design
Conduct detailed user surveys with target demographics (elderly, disabled) to identify critical activities and design intuitive, unambiguous gestures that accommodate physical and cognitive limitations. This phase involves extensive user testing to refine gesture vocabulary.
Phase 2: Data Collection & Model Training
Gather diverse datasets for chosen gesture recognition techniques (IMU, vision-based) from a broad user base under various environmental conditions. Train and optimize ML models (CNNs, Random Forests) to achieve high accuracy, robustness, and generalization across different users and settings. Focus on edge deployment optimization.
Phase 3: System Integration & Pilot Deployment
Integrate the selected gesture recognition system with smart home devices (lights, locks, mobile finders) via BLE or other protocols. Deploy in a pilot environment (e.g., smart home lab, care facility) with target users. Collect performance metrics (accuracy, latency, bandwidth, power consumption) and user feedback.
Phase 4: Iterative Refinement & Scalability
Refine the system based on pilot results, addressing challenges like occlusion, lighting variations, and user variability. Develop adaptive learning algorithms for personalization. Plan for broader deployment, considering scalability, cost-effectiveness, and long-term maintenance in real-world AAL environments.
