This study was an attempt to recognize the effect of a humorous audio-visual stimulus on the autonomic nervous system (ANS) and the heart physiology of females. Electrocardiogram (ECG) signals were acquired from eleven female volunteers under pre- and post-stimulus conditions. Heart rate variability (HRV) and time-domain ECG analyses were performed to non-invasively realize the effect of the humorous...
In recent years, the development of EMG-based assistive technologies has received special attention of the researchers. This can be attributed to the advantages of EMG signal over other biosignals. The present study proposes the development of a dual-channel EMG biopotential amplifier. The biopotential amplifier was designed using INA128 instrumentation amplifier and was used for acquiring EMG signals...
The current study investigates the effect of sound in a horror movie clip on the autonomic nervous system (ANS) and the conduction pathway of the heart. The effect on ANS was explored non-invasively using heart rate variability (HRV) parameters. The results suggested that the physiology of ANS is not significantly affected by the sound stimulus. Electrocardiogram (ECG) signal divulges information...
The current study deals with the development of an ultrasonic based cane for the navigation of the blind persons. The developed cane is able to detect both aerial and ground obstacles and potholes (drop-off). The ultrasonic signals are acquired in the Arduino microcontroller, classified and control signals are generated. The control signals are transmitted wirelessly to the receiving device, kept...
Electromyogram (EMG) — controlled devices are being explored for controlling the functioning of the rehabilitation devices. The main advantage of these devices is the hands-free operation with minimal need for assistance. The present study delineates the development of a wireless EMG control system. The proposed control system was tested using a miniaturized wheelchair model. The proposed control...
In the last decade, there has been an exponential increase in the research being carried out on wearable devices. The research on wearable devices still in its nascent stages and hence there are not many commercial devices available for improving the lifestyle of the differently-abled persons. Hence, in this study, we have made an attempt to device a wearable electronic travelling aid for the blinds...
