Rapid advances in the enabling technologies for mobile and ubiquitous computing help portable devices to join collaborative graphics design conveniently. The limitation of display size and computational power of these embedded devices makes it hard for mobile users to browse large pattern that renewed in real time efficiently. We present a novel user interest region prediction algorithm and related...
A well arranged task priority in dual-shore collaborative software design phase will smooth the collaboration and reduces the potential coordination lag. However, it is really difficult to determine the priority when there are many collaboration tasks and the collaborative process is a little complicated. On the basis of behavior compatibility analysis using Petri-net, this paper proposed yet a new...
Collaborative graphics design systems allow users, spread across different locations, to work together designing common patterns. One key element that, in most cases, is poorly supported in such systems is semantic preservation. To make the real-time collaborative graphics design system more efficient, it is essential that the semantic violation problem be well solved. In this paper we present the...
Coordination mechanism is a critical issue in the cooperative work. However, there are no universal and efficient coordination mechanisms that are fit for the collaborative graphic designing system accounts for it's special characteristic and properties. In this paper we propose a novel intelligent coordination mechanism, which enable members to concentrate on the most of controversial part of the...
Collaborative applications across mobile end and immobile end became more and more popular recently; however, the control over user interface became more intricate or flexible. The clustering of editing objects could give users not only a clear document organization, but also a smart management of operation authority. In this paper we presents an adapted clustering algorithm based on maximal spanning...
Collaborative graphics editing systems in ubiquitous environment support users to join and leave the collaboration dynamically at any time. The shared workspace state of these users will be inconsistent for the modification of the other session members. It is therefore necessary to initialize the application instance of the latecomer with the current state. In this paper, we propose a rejoining scheme...
Video-based channel that can transmit people's facial expression information is designed to support real-time interaction between collaborators. Yet exchanging facial video in ubiquitous environment is confined by the low bandwidth and limited computational resources on mobile embedded devices. In this paper, we present a novel two dimensional (2D) facial animation communication system which enables...
The proliferation of computer devices and wireless networks allows users to access pattern information and collaborative edit graphics with others in ubiquitous environment. However, the limitation of display size and unreliable network of these embedded devices makes it hard for mobile users to browse grouped complicated pattern objects efficiently. We propose semantic group mapping that enable group...
Tracing the movement of telepointer is one of the most efficient ways to aware remote collaborators' drawing actions in real-time Internet based collaborative graphics editing systems. However, delay jitter may occur, which will make the presence of telepointer jumpy and lead to semantic misunderstanding or operation conflicting in collaboration. This paper presents a novel algorithm that predicts...
With heterogeneous devices proliferating, there is a need for collaborative graphics editing systems that are tailored to the capabilities of their current computing and communications environment. Mobile network and device capabilities constrain the application implementation, which implies that the storage space and computing power is limited and network is unreliable. This paper presents a semi-replicated...
This paper proposes a novel late join approach for dynamic locking mechanism (DLM) in Internet-based real-time collaborative editing systems. The main idea is that: in the process of late join, four cases are classified according to the situations of whether the user has enabled the DLM or not and whether the user is in the session or not. And different transmission steps are adopted for each case...
