On Machine Operator Guidance

Properly supported operator guidance can have huge benefits to productivity and site safety, especially for less experienced operators. Creating well-integrated operator guidance systems needs careful consideration of multiple aspects, such as how the information is broadcast, the placement of displays and the overall design of the HMI. 

CrossControl, working with Mälardalen University Sweden, has been testing machine control interfaces and operator guidance. Building custom rigs to test user’s experience of mixed reality interfaces showed that a key factor in aiding operators and reducing fatigue was in the placement of the display. With the wide range of displays from CrossControl it is easier for OEMs to find the right solution for each machine and gain the most benefit from on-board HMI solutions whether they include AR or more a more traditional format.

One new technology that enables even further integration is Augmented Reality. Current solutions enable the use of in-display AR to give operators detailed task direction and help drivers to easily orient themselves in their surrounds for increased safety, simpler navigation and quicker maneuverability. Using image detection, information can be placed in line of sight to enable an integrated guidance and warning system.

More advanced AR solutions will be coming to construction sites in the coming years with the advancement of Head-Up display solutions in the windscreen, as well as driver worn AR headsets. Markus Wallmyr, researcher at Mälardalen University Sweden and the Global UX Lead at CrossControl, has been investigating the next stage of Human Machine Interactions as we move into Industry 4.1. As such he has been part of initiating an EU wide study researching the effectiveness of these newer AR solutions.

AR simulations and tests carried out by Markus Wallmyr showed how the advantages of more finely tuned guidance offered gains in both productivity and information intake. Additionally users reported less fatigue and an increased ease of use when the display was more closely aligned with their natural line of sight. It is also of note that even as AR solutions become more refined, due to advanced implementation, adaptive software platforms, tailored to support specific tasks, will remain important in realising its full benefits.
