Definitions

• the invention relates to a device for learning a manual technique by an operator.
• the invention also relates to a learning method implemented with the device.
• One possible application of the invention is that of welding training.
• Another possible application of the invention is that of learning to paint with a gun or the removal of putty.
• document WO 2006/034571 discloses a training device for welding, by representing parts to be welded in three dimensions with a gripping member representing the tool to be welded. The gestures of the operator are recorded, so as to obtain a simulation of these gestures on a computer, which is projected on a screen visible to the operator.
• the screen thus allows the operator to view his action in real time, and to obtain data on the consequences of actions performed by the operator.
• this device requires that this visualization is performed in the viewing window of a mask or goggles whose use is necessary for the welding operation.
• such a device is relatively complicated insofar as it requires means of communication between the headset and a computer from which the simulations come, as well as a display window of the headset allowing a display, which can be used. prove particularly expensive.
• the existing devices have a level of realism that is not completely satisfactory and that do not facilitate an ideal autonomous learning.
• An object of the invention is therefore to provide a device for learning a manual technique by an operator, usable for many applications.
• Another objective of the invention is to propose such a device, which is clearly simplified in its implementation and therefore inexpensive.
• Another goal is still to provide an improved level of realism.
• a device for learning a manual technique by an operator which comprises a gripping member representative of a tool intended to be handled by the operator, a representative physical medium of an object to be worked, means for detecting the gripping member, the physical medium and movements effected by the operator, as well as means for processing and controlling the various means constituting the device, in particular processing the detected operator movements, and information projection means to the operator, and for which the physical medium and the information projection means are arranged relative to one another so that the information is projected on the physical medium, even if there is no contact between the gripping member and the physical medium.
• the device 1 for training a manual technique by an operator comprises a gripping member 2, a physical support 3, detection means 4 for detecting both the gripping member 2, the physical support 3 and the movements performed by the operator.
• the gripping member 2 is representative of a tool intended to be handled by the operator.
• the gripping member 2 in question may be a real tool or will have an ergonomics identical to that of a real tool.
• the physical support 3 is representative of an object to be worked with the gripping member 2. Again, one will choose either the real object to be worked, or a physical support 3 whose ergonomics are identical to that of the real object.
• the physical support 3 will preferably be fixed relative to the ground.
• the device also comprises means 5 for processing and controlling the various means constituting the device.
• processing and control means 5 deal in particular with the movements of the operator detected by the detection means 4, to determine, for example, the position and the speed thereof or the actions taken. In particular, these means make it possible to compare the gestures made by the operator to gestures made by an expert, and which have been previously recorded.
• the processing and control means 5 also process the context data (noise, temperature in the environment of the room) of the device.
• the device 1 also comprises information projection means 6 previously processed by the processing and control means 5 to the operator.
• This visual information concerns, for example, the result of movements made by the operator, assistance information to the operator (speed, position of the gripping member for example),
• These information projection means 6 are arranged relative to the physical medium 3 so that the information is projected on the physical medium 3, even if there is no contact between the gripping member 2 and the physical support 3. They comprise one or more projectors according to the shape / geometry of the physical support 3, in particular to avoid the shadows.
• the device 1 may further comprise means for transmitting sound information 7 to the operator, for example with one or more speakers or headphones.
• the device 1 may further comprise means for transmitting tactile information 8 to the operator.
• These means for transmitting tactile information 8 may be disposed within the gripping member 2, or within the physical medium (3), or at the ground level, depending on the nature of the tactile information to be restored.
• the sound and tactile information transmission means 8 are under the control of the processing and control means 5.
• the device also comprises a display station 9, connected to the processing and control means 5, for displaying summary information on the movements performed by the operator.
• the detection means 4 are arranged, with respect to the gripping member 2, the physical support 3 and the operator, so as to provide the processing means 5 and control 5, the spatial and angular coordinates of these in real time.
• the physical support 3 may be a support in two dimensions, but will preferably be three-dimensional to best represent the forms of the object that the operator will actually work once his training is completed.
• the learning method implemented via the device 1 consists mainly in projecting information on the physical medium 3, this information concerning just as many results / estimates on the actions performed as assistance information for the operator.
• the physical support 3 will preferably be solid, non-malleable. Also preferably, it will represent an object that, although it may be complex, will have no or few cavities, so that the spotlight (s) forming the projection means 6 can correctly illuminate the physical support 3.
• the invention therefore does not require the use of a helmet having a window on which information is projected, because the information is directly projected on the physical medium 3.
