In mining industry, the introduction of operating from long distance Tele-operated mining has led to lost of rich information for the rock operator working from remote location. The feedback from the machine is limited, resulting in lack of involvement for the operators in the task.

How to enhance operator's support in tele-operated mining environments? The objective was to develop a concept for an operator environment for a remote-controller rock breaker.

 

Iwa : tangible workstation

The proposed future workstation based on the multi-modal interface that empowers the rock operator to make key decisions while operating. It provides tactile information focusing on connecting the operator and remote location information including visual and auditory feedback.

CONCEPT : Operator in Focus

In future work environment several operators work in a collaborative office like environment. The system is deciding and notifying the operators which pit unit needs attention based on which one has a rock stuck on the Crusher. The multi-modal workstation interface empowers the operator to make decision and improves the involvement in the task. The concept envisions engaging the rock operator in the task in Tele- operated mining.

 

DETAILS : Interaction touch points

Interaction elements concept consists of four main points of interaction: screen, Crusher Palette, Pointer (handheld device) and Control Panel.

Dynamic surface

Palette is the metaphor of the Crusher pit, an operating surface with two modes, engraved fractures and 3D; operator can switch back depending on the desired level of haptic feedback. It allows the exploration of rock surfaces for a decision making process.

Rock exploration

It provides haptic feedback and allows the exploration of surfaces for a more careful and engaging decision making process.

OPPORTUNITY MAPPING

After the user research of interviewing and observing various industries, we clustered the obtained information into three main different directions. How can the Rock Operator be highly involved & provided with valuable feedback in a tele- Operated remote mining environment?

Tangible Feedback Increasing automation makes it challenging to involve the operators. How to increase operator’s involvement levels by making the experience of breaking the rock more engaging within 15 years.

 Improving vision The operators lack visual cues of the rocks in camera images while operating. How can visual be improved for the operator.

Shift in the role of the rock operator Bad environmental conditions in mines and is shifting automatic. What’s the role of the operator going to be in automated future? Decision making, multi-task supervision Interdependent and network system.
