“…Taking evoked potential analysis as an instance particular in the field of clinical anesthesia, evoked potential monitoring by BrainIC serves as an objective measure of the inhalation anesthetics central inhibition. Additionally, one would be diagnosed as addiction, epilepsy, attention deficit hyperactivity disorder, stroke, Alzheimer's disease, multi-infarct dementia, and so forth by quantitative BEAM analysis [56,81–83]. …”

“…Due to a high common mode rejection ratio, merely the difference between the polarization voltages on input terminals makes contribution to the output, that is, the amplifier is operated in the linear region. Accordingly, the gain of this amplifier can be made as high as possible [56,57]. …”

“…The amplitude difference between the channels has enabled the determination of 360-degree eye ocular direction. Applications such as computer interfaces [ 9 , 10 , 11 , 12 , 13 ], wheelchairs [ 14 , 15 , 16 , 17 ], and robots [ 18 , 19 , 20 ] using the same operation input as the cross-keys are demonstrated. As a notable example in robotic application, Eduardo Iáñez et al [ 19 ] conducted an object displacement task using a robot arm where the eye’s direction controls the direction of the arm.…”

Object Grasp Control of a 3D Robot Arm by Combining EOG Gaze Estimation and Camera-Based Object Recognition

et al. 2023

The purpose of this paper is to quickly and stably achieve grasping objects with a 3D robot arm controlled by electrooculography (EOG) signals. A EOG signal is a biological signal generated when the eyeballs move, leading to gaze estimation. In conventional research, gaze estimation has been used to control a 3D robot arm for welfare purposes. However, it is known that the EOG signal loses some of the eye movement information when it travels through the skin, resulting in errors in EOG gaze estimation. Thus, EOG gaze estimation is difficult to point out the object accurately, and the object may not be appropriately grasped. Therefore, developing a methodology to compensate, for the lost information and increase spatial accuracy is important. This paper aims to realize highly accurate object grasping with a robot arm by combining EMG gaze estimation and the object recognition of camera image processing. The system consists of a robot arm, top and side cameras, a display showing the camera images, and an EOG measurement analyzer. The user manipulates the robot arm through the camera images, which can be switched, and the EOG gaze estimation can specify the object. In the beginning, the user gazes at the screen’s center position and then moves their eyes to gaze at the object to be grasped. After that, the proposed system recognizes the object in the camera image via image processing and grasps it using the object centroid. The object selection is based on the object centroid closest to the estimated gaze position within a certain distance (threshold), thus enabling highly accurate object grasping. The observed size of the object on the screen can differ depending on the camera installation and the screen display state. Therefore, it is crucial to set the distance threshold from the object centroid for object selection. The first experiment is conducted to clarify the distance error of the EOG gaze estimation in the proposed system configuration. As a result, it is confirmed that the range of the distance error is 1.8–3.0 cm. The second experiment is conducted to evaluate the performance of the object grasping by setting two thresholds from the first experimental results: the medium distance error value of 2 cm and the maximum distance error value of 3 cm. As a result, it is found that the grasping speed of the 3 cm threshold is 27% faster than that of the 2 cm threshold due to more stable object selection.

An antenna sensor is proposed to play dual role of a functional antenna and a sensor in a wireless sensor system, in an effort to reduce data loss and to increase transmission rate by eliminating a certain interface. A function of protractor was implemented on the coil antenna, working at radio frequency, to demonstrate the antenna sensor. The coil antenna was made of a copper wire with a wire diameter of 1 mm and had a coil diameter of 60 mm. With the impedance matching for the antenna designed at a resonant frequency of 43 MHz, a signal composed of multiple waves at shifted frequencies was transmitted from a mixer to the bent coil sensor, which acts as the emitting antenna. Upon received at the receiver coil, the signal was analyzed using the fast Fourier transform (FFT) algorithm. The received frequency‐domain signals were used to establish the characteristic matrix for the antenna sensor during a calibration process. The characteristic matrix becomes the fingerprint pattern to identify test angle of the bent coil sensor through the calculation of the Euclidean distance based upon the k nearest neighbor (kNN) classifier of the machine learning. The results showed that all the 16 test angles were identified accurately in the correct angle range.
