The correct sitting posture in a wheelchair is crucial for paralyzed people. This helps prevent problems such as pressure ulcers, muscle contractures, and respiratory problems. A paralyzed person with poor sitting posture is highly likely to slip out of their wheelchair. To prevent this from happening and consistently maintain paralyzed individuals under observation, a new model, the Emperor Penguin Optimized Sensor-Infused Wheelchair (EPIC), has been designed to monitor the position and health of the individual in the wheelchair in real-time. A Force Sensitive Resistor (FSR) sensor and an ultrasonic sensor continuously transmit information to the Arduino UNO R4 Wi-Fi board. The Emperor Penguin Optimizer Algorithm (EPOA) was used to select the features sent from the Arduino board to the ESP8266-Wi-Fi module. A Deep Maxout Network (DMN) was used to predict the posture of a wheelchair-using patient following the feature selection phase. A mobile application for Android collects data from the ESP32 module and estimates posture to inform the caretaker about the user's current posture and health status. Evaluation metrics such as precision, accuracy, sensitivity, and specificity have been used to determine the efficiency in the EPIC framework, which improves overall accuracy by 10.1%, 7.73%, and 2.84% for better posture recognition.
对于瘫痪者来说,在轮椅上保持正确的坐姿至关重要。这有助于预防诸如压疮、肌肉挛缩和呼吸问题等。坐姿不佳的瘫痪者很可能会从轮椅上滑落。为防止这种情况发生并持续对瘫痪者进行观察,设计了一种新型号——帝企鹅优化感应轮椅(EPIC),用于实时监测轮椅上人员的位置和健康状况。一个力敏电阻(FSR)传感器和一个超声波传感器持续将信息传输到Arduino UNO R4 Wi-Fi板。帝企鹅优化算法(EPOA)用于选择从Arduino板发送到ESP8266-Wi-Fi模块的特征。在特征选择阶段之后,使用深度最大池化网络(DMN)来预测使用轮椅患者的姿势。一款适用于安卓系统的移动应用程序从ESP32模块收集数据并估计姿势,以便告知护理人员用户当前的姿势和健康状况。在EPIC框架中,已使用诸如精确率、准确率、灵敏度和特异性等评估指标来确定效率,该框架在更好的姿势识别方面将总体准确率提高了10.1%、7.73%和2.84%。
