| Outline of Final Research Achievements |
In this research, we focused on motion sensors and aimed to estimate gaze / visual field information during bathing assistance. As a motion sensor, data was collected at 1 kHz by fixing small sensors composed of tri-axial acceleration, tri-axial angular velocity, tri-axial geomagnetism and GPS to the subjects. As a result, the accuracy of the gaze estimation using the motion sensor with reference to the line of sight target coordinates had an error of about 16 degrees at the maximum. However, it can be estimated within 10 degrees at a time of 90% or more, and it was confirmed that the estimation accuracy is high. Furthermore, an error of 15 degrees occurred when the target movement was about 1.5 m per second, but it was within 10 degrees at a speed lower than 1 m / s. If it is a slow motion such as bathing aid, it can be confirmed that the accuracy is within 10 degrees.
