Abstract

A work machine includes: a work device configured to change a shape of an object in a work range of the work machine; and a display device configured to recommend, in a visible way, a target work location in the work range of the work machine, based on information about a current shape of the object, the target work location being where the work device changes the shape of the object.

What is claimed is: 
     
         1 . A work machine comprising:
 a work device configured to change a shape of an object in a work range of the work machine; and   a display device configured to recommend, in a visible way, a target work location in the work range of the work machine, based on information about a current shape of the object, the target work location being where the work device changes the shape of the object.   
     
     
         2 . The work machine according to  claim 1 , wherein the display device is further configured to display, in a distinguishable way, a location of relatively high recommendability and a location of relatively low recommendability as potential target work locations in the work range of the work machine. 
     
     
         3 . The work machine according to  claim 2 , wherein the display device is further configured to display difference between the high recommendability and the low recommendability by using varying colors or varying numerical values. 
     
     
         4 . The work machine according to  claim 3 , wherein the display device is further configured to display difference between the high recommendability and the low recommendability by using a heat map. 
     
     
         5 . The work machine according to  claim 2 , wherein the display device is further configured to display a location in the work range of the work machine where recommendability shows a maximal value. 
     
     
         6 . The work machine according to  claim 2 , wherein the display device is further configured to display an indication that no work location is recommendable when no work location in the work range of the work machine shows relatively high recommendability with respect to a predetermined criterion. 
     
     
         7 . The work machine according to  claim 2 , wherein the high recommendability and the low recommendability are defined in association with job efficiency or safety of the work machine. 
     
     
         8 . The work machine according to  claim 7 , further comprising a processing device configured to output a distribution of recommendability in the work range of the work machine, based on the information about the current shape of the object in the work range of the work machine, by using a trained model that has been machine-learned using training data that is associated with the shape of the object and that is modeled on operation of the work machine by an operator with relatively high expertise based on a predetermined criterion. 
     
     
         9 . The work machine according to  claim 1 , wherein the display device is further configured to recommend, in the visible way, a plurality of potential target work locations in a time sequence based on the information about the current shape of the object in the work range of the work machine. 
     
     
         10 . The work machine according to  claim 1 , wherein the display device is further configured to recommend, in the visible way, the target work location in the work range of the work machine, and a path that a working part of the work device follows when the work device changes the shape of the object in the work range of the work machine, based on the information about the current shape of the object. 
     
     
         11 . The work machine according to  claim 1 , wherein the display device is further configured to display an image of a recommended target work location in the work range of the work machine by overlaying the image of the recommended work location over an image showing the current shape of the object. 
     
     
         12 . The work machine according to  claim 1 , wherein the display device is further configured to display an image of a recommended target work location in the work range of the work machine, within a field of view of a user of the work machine who is viewing the work range of the work machine from a cockpit of the work machine. 
     
     
         13 . The work machine according to  claim 1 , wherein the display device is further configured to display an image of a recommended target work location in the work range of the work machine by projecting the image of the recommended target work location over the work range of the work machine. 
     
     
         14 . A remote operation assisting device comprising:
 an operating part configured to allow a user to remotely operate a work machine having a work device for changing a shape of an object in a work range of the work machine;   a communication part configured to transmit information about an operating state of the operating part to the work machine; and   a display part configured to recommend, in a visible way, a target work location in the work range of the work machine, based on information about a current shape of the object, the target location being where the work device changes the shape of the object.   
     
     
         15 . An assisting system for assisting operation of a work machine having a work device that is operated by a user when changing a shape of an object in a work range of the work machine, the assisting system comprising:
 a display device configured to recommend, in a visible way, a target work location in the work range of the work machine, based on information about a current shape of the object, the target work location being where the work device changes the shape of the object.
