“…Kurata et al [12,13] developed the WACL system that involves the worker wearing a steerable camera/laser head. WACL allows the remote instructor not only to independently look into the worker's task space, but also to point to real objects in the task space with the laser spot.…”

“…Therefore, the instructor can observe around the worker, independently of the worker's motion, and can clearly and naturally instruct the worker in tasks. Previous work in the area of remote guiding of mobile workers has mostly focused on supporting pointing to remote objects, using a projection based approach such as the laser pointing system in WACL [12,13], or using a see through based approach such as in REAL [17] (see Fig. 2).…”

“…MixedEcology aims to promote mutual awareness between participants, by supporting the remote guiding through a mixed reality surface in which the remote helper's hands are overlaid on top of the local worker's hands. Kurata et al [12,13] developed a Wearable Active Camera with a Laser pointer system (WACL). In this system, the worker wears a steerable camera/laser head.…”

Rapid advances in networking and hardware have made it possible for remotely located individuals to perform physical tasks. Recently a number of systems have been developed with each supporting a different scenario of remote collaboration. Of particular interest to us is to explore the value of these technologies in the context of mining. As automation is being introduced in mines, more and more skilled operators are operating remotely. As a result, onsite operators' job becomes more complex and requires input from remote skilled operators. The productivity of the future mine relies on the effective delivery, just in time, of remote guidance. This paper presents a remote guiding system called HandsOnVideo, which is developed as part of our Human System Integration project within the CSIRO's Minerals Down Under (MDU), a National Research Flagship. Our aim is to design and develop a system that supports a remote helper guiding a mobile local worker in maintaining complex equipment in mine sites. The system is developed following a participatory design approach and the results of a usability study with real users indicate that the system is useful and effective.

“…To solve the problem of transmission of positional information on an object by pointing gestures in remote communications, many systems using laser pointers have been presented [4][5][6][7]. These systems are essentially composed of a camera whose posture can be controlled flexibly by remote control, and a laser emitting device.…”

SUMMARYOwing to the widespread use of the Internet and portable phones, long-distance human communication is becoming convenient and is being widely used in daily life. In particular, with portable phones, real-time voice communications can be realized between widely separated locations, regardless of where, and at any time. This paper proposes a real-time remote communications support system (mutual view-sharing system) in which the views seen by the parties can be shared in real time by means of an eyeglass-type face-mounted display, a small camera attached above the eye of the user, and a wearable PC. When this system is used to communicate with another party at a distant location, the displays on both sides maintain the same "shared view." The "shared view," in which one party's view is shared with the other party, contains the image obtained from one party's face-mounted camera and also an image of the hand of the other party. When the view of the other party is shared, the "shared view" combines the image obtained from the face-mounted camera of the other party and also the speaker's own hand image. This mechanism makes it possible, even if the other party is at a distant location, to share a view of the subject of the conversation visually and to transmit positional information on the subject by means of pointing gestures. The system is completely wearable, and the parties communicate while appropriately switching between the shared views. Thus, the system can be considered as an extension of the portable phone. This system was used to perform a real-time remote communications experiment with the content of "asking the other party to find an object." It was shown that the system is especially useful compared to voice-only communications when the shape of the subject of the conversation is complex and the other party has no knowledge of the subject.

“…This latter can only provide audio indications. Sakata and Kurata (Sakata et al, 2003), (Kurata et al, 2004) developed the Wearable Active Camera/Laser (WACL) which allows the remote instructor not only to independently look into the worker's task space, but also to point to real objects in the task space with the laser spot (Alem et al, 2011). In (Bottecchia et al, 2010) a maintenance collaborative system entitled CAMEKA is described, which enables the expert to give visual indications to an operator with an AR display device fitted with a camera.…”
