AB  - Collaborative environments today are very successful when used in multiplayer games and for meetings organizing, which gives an idea to explore its potentials in remotely controlled decentralized manufacturing. This survey is based on the experiment that involved 34 small collaborative groups including 68 students in Serbia, that have used the interface for remote collaborative control of manufacturing systems to control of CNC machine located in Portugal. Our previous surveys have shown that group work consumes less time than individual work in most working options. This paper examines influence of homogeneity of the groups. Results of statistical examination show that percentages of errors are significantly or highly significantly higher in homogeneous compared to a non-homogeneous groups. Therefore, it could be recommended to form heterogeneous groups when remotely controlling decentralized manufacturing processes.

AB  - Recent advances in information and communication technologies that support the concept of collaborative networks have allowed manufacturing enterprises to use remotely controlled decentralized manufacturing processes. This survey is based on the experiment that involved 34 small collaborative groups at Serbia, that have used the interface for remote collaborative control of manufacturing systems to control of CNC machine located in Portugal. The experiments on collaborative environment are done using two types of “client” user interface, “Wall” and “Window”. Measured characteristics included: collaborative effort, involvement, awareness, representational fidelity features and co-presence. Results show that “Wall” interface has higher values of index of interdependence of collaborative virtual environment characteristics. Conclusion is that characteristics of collaborative environment are less interdependent when “Window” is used opposite to the “Wall” interface. Future research ideas are to test similar platforms with more users and to study aspects such as group leader choice and role, possible conflicts etc.

AB  - Recent economic crisis has shown that classical approach to individual and local product oriented company is not sustainable in modern economic reality. Possible solution lies in high degrees of both specialization and flexibility product oriented small and medium-sized interchangeable production systems. According to that new wave, the main idea is based on exploring and testing of new possible designs and ways of control of human-computer interfaces for remote control of complex distributed manufacturing systems. Herein, the proposed remote system with Wall interface, video beam presentation mode and using group work enables producers in manufacturing sector to offer a product, through outsourcing manufacturing process and system in a global chain, utilizing ubiquitous computing systems and virtual and networked enterprises concepts, for anywhere-anytime control and give benefits to education sector, too, since students can dynamically interact with a real process to get a remote experimental practice, guaranteeing the availability of lab resource.

AB  - The present invention is directed to manufacturing, wherein each component of the outsourced process and system can be remotely controlled in decentralized manufacturing process, integrating resources and stakeholders in a global chain, that utilizes ubiquitous computing systems virtual and networked enterprises concepts, for anywhere-anytime control. Experiment involved 68 subjects, Serbian students that have used the interface for remote collaborative control to control CNC machine located in Portugal. Usability evaluation measures of the distributed remote user controlled manufacturing system, such as percentage of task completed, its accuracy and time to complete task, are measured on two types of "client" user interface ("Wall" and "Window"), in two modes of presentation (desktop and video beam), working individually or in small collaborative group consisted of two persons, results were statistically tested. Percentage of task completed is equal for both types of interfaces, while accuracy of task is significantly better for "Wall" interface. Time of task execution is longer for individuals when desktop is used comparing to video beam. There exist significant differences when work is conducted in groups via video beam and time is longer when desktop is used. Also, work time is longer with "Wall" interface. When working in group, work time is shorter than the time when working individually, whereby the working time on desktop is longer than on the video beam. Also, the time is longer when working individually using video beam, using "Wall" interface on desktop, and "Window" interface on video beam. These results show that group work consumes less time in most working options, giving the best results when working in collaborative small group on "Wall" interface via video beam.

In this survey, the experiments on representational fidelity measures are performed on two types of 'client' user interface (Wall and Window) in two modes of presentation (Desktop and Video beam) of the distributed manufacturing system. The proposed remote system has allowed students from Belgrade, Serbia to dynamically interact with a real manufacturing process held in Minho's Lab, Portugal, to carry out a remote experimental practice. This survey gives advantage to Wall interface, in the fields of smooth display of view changes and object motion and consistency of object behaviour. There are also weaker correlations between representational fidelity measures when Wall interface is used and certain advantage on desktop presentation mode.

AB  - Rad predstavlja doprinos novom pravcu unapređenja daljinskog upravljanja funkcionalnostima i prezentuje metodologiju za procenu korisničkih interfejsa za daljinsko upravljanje ubikvitnim proizvodnim sistemima. Istraživanje je zasnovano na eksperimentu, koji je uključio 68 ispitanika, studenata Mašinskog fakulteta Univerziteta u Beogradu, koji predstavljaju buduće korisnike interfejsa za daljinsko kolaborativno upravljanje proizvodnim sistemima. Rezultati pokazuju da se instrument za ocenu sastoji od koreliranih mera korisnosti i kolaboracije. Korisnost sadrži mere efikasnosti, efektivnosti i reprezentativne tačnosti, dok kolaboracija uključuje napor, uključenost i koprisutnost. Rezultati rada treba da pomognu pri odlučivanju u budućem dizajniranju i pri merenju kvaliteta upotrebe.
AB  - This paper is a contribution to the new direction for enhancement in remote controlling functionality in manufacturing systems and presents a methodology for evaluating user interfaces for the remote control of a Ubiquitous Manufacturing System. Survey is based on the experiment that involved 68 subjects, students at the Faculty of Mechanical Engineering, the University of Belgrade, Serbia, as future users of the interface for the remote collaborative control of manufacturing systems. The results show that the user evaluation instrument consists of usability and collaboration as correlated measures. Usability comprises effectiveness, efficiency and representational fidelity measures, while collaboration includes collaboration effort, awareness/involvement and copresence. The results of this survey will help in future design decisions and measuring its quality of use.

AB  - Rad prikazuje novi pristup unapređenju tradicionalnog daljinskog upravljanja u proizvodnim sistemima zasnovan na obezbeđenju funkcionalnosti pragmatičnog nivoa komunikacionih kanala. Korišćenje raznovrsnih pristupa i metodologija, poput video konferencije, računarski podržanog kooperativnog rada, virtuelne stvarnosti, alata drugih virtuelnih okruženja, kao što su "Metaverse" internet veb pragmatični alati, je neophodno u cilju prevazilaženja problema prostorne barijere. Stoga je dalja analiza korisničkog interfejsa čovek-mašina presudna za interakciju korisnika sa proizvodnim sistemom preko daljinskog upravljanja unutar postavljenih okvira. U ovom radu su prikazani preliminarni rezultati evaluacije dva tipa korišćenih interfejsa, koji se naročito razlikuju sa prezentacionog aspekta, dok su funkcionalnosti daljinskog upravljanja iste za oba tipa interfejsa. Rezultati analize ocena korisnika, pokazuju da je jedan interfejs sa aspekta korisnika, ocenjen nivoima različitih faktora, bolje od drugog.
AB  - This paper refers to the new direction for enhancement in traditional remote controlling functionality in manufacturing systems. Employing a diversity of tools such as videoconferencing, computer supported cooperative work tools, immersive virtual reality, virtual environment tools, such as "Metaverse" tools, and Internet through Pragmatic Web, is necessary for overcoming the "space barrier". Therefore, further analysis of human-machine user interface is crucial for user interaction with manufacturing systems through remote control. That is the motivation for investigation on evaluation of the user interfaces for remote control of manufacturing systems within the above-mentioned framework. Preliminary results of the evaluation of two types of interfaces are presented in this paper. These two interfaces are distinctive in one particular presentational aspect, while all the remote controlling functionalities are equal for both. The results show that one user interface type clearly fares better than the other over a number of factors as graded by users.
