Title:
REMOTE OPERATION ASSISTANCE DEVICE AND REMOTE OPERATION ASSISTANCE METHOD
Document Type and Number:
WIPO Patent Application WO/2021/230090
Kind Code:
A1
Abstract:
Provided, inter alia, is a device with which it is possible to achieve a recognition result relating to the state of operation of a work machine by an operator remotely operating the work machine, the recognition result being close to the recognition result by the operator relating to the operation state of the work machine when the operator is riding the work machine. The sound output state of each of a plurality of acoustic output devices 2220, 2221, 2222 positioned in each of differing locations in a remote operation space for an operator operating a remote operation device 20 is controlled on the basis of the detection result for the operation state of the remote operation device 20, when the relative motion of a first constituent element (lower traveling body 410, upper turning body 420) and a second constituent element (upper turning body 420, bucket 445 (work unit)) that constitute a work machine 40 is represented. It is thereby possible to displace a virtual point sound source SP1 according to indicated position trajectories (time series of positions) tr1, tr2 that are set according to the relative motion state of the second constituent element in relation to the first constituent element.
