“…For example, users can use their portable devices such as cell-phones, PDAs (Personal Digital Assistants) or laptops to display the instructional screen inside a department store for a better adoption of guidance. In addition, users are able to stream a wall-sized, high-resolution tiled display to portable devices [6,7]. Furthermore, if the middleware has been integrated with motion and voice commands [8], functionalities like automatically selecting a nearest screen based on the user's motion or volume can be effortlessly implemented.…”

Electronic visual display enabled by touchscreen technologies evolves as one of the universal multimedia output methods and a popular input intermediate with touch–interaction. As a result, we can always gain access of an intelligent machine by obtaining control of its display contents. Since remote screen sharing systems are also increasingly prevalent, we propose a cross-platform middleware infrastructure which supports remote monitoring and control functionalities based on remote streaming for networked intelligent devices such as smart phone, computer and smart watch, etc. and home appliances such as smart refrigerator, smart air-conditioner and smart TV, etc. We aim to connect all these devices with display screens, so as to make possible remote monitoring and controlling a certain device by whichever one (usually the nearest one) of display screens among the network. The system is a distributed network consisting of multiple modular nodes of server and client, and is compatible to prevalent operating systems such as Windows, macOS, Unix-like/Linux and Android, etc.

“…VNC has been studied as a tool for both synchronous and asynchronous collaboration [1,2]. VNC has also been used collaborative tools such as wall-sized and tabletop displays [3][4][5][6]. The ability to run multiple sessions on a single server offers other more system-related advantages as well.…”

“…Because it is open source, VNC has been one of the more popular systems for thin client research. Research on VNC has included adapting it for high resolution tiled displays, adapting it to control home appliances, and adapting it for optimal viewing on cellular phones, as well as trying new data compression schemes [3,4,[16][17][18][19]. With its use in both real world and academic settings, VNC is one of the most ubiquitous thin client systems.…”

Improving video performance in VNC under high latency conditions

Virtual Network Computing, or VNC, is a popular thin client application used to access files and applications on remote computers. However, VNC can suffer from significant losses in throughput when there is high latency between the client and server. These losses become especially apparent in the case of video, where updates are both large and frequent. In this work, we present a Message Accelerator proxy for VNC. This simple but highly effective solution mitigates high latency network effects for video performance while maintaining the advantages of a client-pull system. By operating near/on the server, it can send updates to the client at a rate corresponding to proxyserver interactions which are faster than client-server interactions. When testing using video, our Message Accelerator design results in frame rates an order of magnitude higher than plain VNC when running under high latency conditions.

“…However, the resolution of the remotely displayed content usually matches the resolution of the local computer's display. Although, some remote desktop systems support higher virtual resolution (such as the Windows Remote Desktop Protocol (RDP) [17] supporting a maximum resolution of 4096x2048), they still do not utilize the full resolution of typical display walls, and such systems have performance problems with increasing number of pixels [15]. In addition, some desktop applications have a predefined layout for the graphical user-interface.…”
