“…Consequently, the users perceived much small variations in interaction under the DP strategy. We derived the DP strategy from a SP strategy [3]. The SP strategy resolves conflicting interactive commands by using a pre-defined and non-changeable priority corresponding to a pre-assigned interactive role of each user, assuming that each user has a unique role.…”

“…Basically, FCFS promotes "winner-takes-all" for the most agile user to take control of interaction with a shared object and thus to prevent the less agile users from taking part in collaboration. An improved version of the FCFS strategy, called the SP strategy, assigns each user a priority based upon his/her predefined role in the interaction [3]. For example, the user who functions as a presenter has a higher priority than other users who play a role of audience.…”

“…On one hand, the strategies of conflict avoidance often restrict each user to interact with an object within a distinctive region and impose the rule of non-simultaneous interaction with an object in a specific shared region. The distinctive region is either statically pre-defined before commencing collaboration [3] [4] or dynamically changeable during undertaking collaboration [5]. When the conflict of interactive commands is inevitable in the shared region, the users should follow specific 'social protocols' -a set of behavioral rules imposed among the users -to handle the conflict [5] [6].…”

“…Nevertheless, the 'social protocols' are in general useless due to the overhead of imposing the rules and cause dissatisfaction among the users [5]. Many studies have employed the strategies of conflict avoidance in applications of multi-touch tabletops and large tiled-displays [3] [4] [6] [7].…”

“…On another hand, the strategies of conflict resolution cope with the conflict of interactive commands by granting one of the users an exclusive access to a shared object. The exclusive access arises when the user has a pre-defined static priority (SP) higher than the other users [3]; or when the user issues an interactive command at the earliest instant among the users with the same priority. The latter is referred as first-come-first-serve (FCFS) and depends dynamically upon each user's agility of issuing an interactive command.…”

Multi-user collaborative virtual environments (VEs) need strategies of conflict resolution to handle simultaneous interaction with shared objects. Current strategies are first-comefirst-serve (FCFS) and predefined static priority of each user. These strategies cannot provide each user with a perceived equal opportunity of interaction and often lead to perceived unfairness to abandon collaboration. To offer an equal opportunity, we created a dynamic priority (DP) strategy and compared the strategy with the FCFS strategy based upon subjective perception of multiple users. Visual or haptic (pertinent to the sense of touch) cues assisted each user to perceive his/her gaining of interaction. We observed that the DP strategy yielded significantly an equal opportunity of interaction. The haptic cue offered lower variations in perceiving the equality than the visual cue under the DP strategy. These observations imply a potential application of the DP strategy in a VE, where various experts require equal opportunities in collaboration.
