Communication and Interaction in Machine Mediated Multimodal LearningSystems: Some Design IssuesRoger HartleyUniversity of Leeds UK, LS2 9JTj.r.hartley@AbstractCommunication in learning systems not only involves structured content but affect and empathy to assist the delivery of meaning and to sustain engagement. In multimodal presentations gestures canbe used to reinforce these attributes and provide semantic integration of the visual and verbal modalities. We report on comparative studies between different presentation formats employing gestures, and their influence on learning comprehension. In contrast, for online multimodal simulations, computing systems have to take more active and knowledgeable roles to support interactions in ways that provide an adaptive framework for engagement and reflective discussion. A simulation project directed at decision making skills is used to focus on these design issues.1. Communication in Multimodal PresentationsM uch multimedia research has considered how learning materials should be assigned to the visual/verbal modalities since these are cognitively processed in different ways (cf [6]). In the assignmentof material to these modalities by [5], their recommendations were concerned with redundancy and with the reduction of cognitive load [7]. These principles suggest students learn better when verbal information is presented as speech rather than as on-screen text, when the materials do not require a split attention between mutually referring information, and when visual and verbal modalities are carefully synchronized. Hence, in M ultimodal Presentations where there has to be a semantic integration of visual/verbal modalities if the communication is to be effective [4], we believe gestures assist in fulfilling this function. We describe gestures under a semiotic framework noting the gesture icon (e.g. pointing finger, open, cupped, or flat hand), its trajectory/dynamics and its referent (e.g. a visual, a mental model, or as an empathic indicator). But gestures are closely coordinated with speech, with what is said and how that content is expressed through pace, emphasis, and intonation.In our experiments with multimodal presentationsin science, some gestures take on a locative function; some are illustrative of process (e.g.expansions and contractions); some illustrated abstract knowledge, e.g. pulling gestures to indicate force, or equilibrium, with the speech pausing to focus attention on these actions. Rhythmic beating gestures often reinforced the cadence and structure of the speech. Hence, gestures—through their choreography—elaborate communication, bringing in affect and empathy and, through their coordination with speech and visuals, the boundaries between perception, cognition and affect are merged.Our comparative experiments are using presentational forms, some of which curtail or limit the scope of gestures in order to judge the contributions of gestures to comprehension and learning and how they are effective. Preliminary results will be discussed, and [1] note that even telepointing experiments have learning benefits in retention and in time-on task measures. But do gestures lessen the cognitive/ affective/empathic load in comprehension, and/or do gestures help presenters to access thoughts and words more readily, and so dynamically assist the structuringof material as it is being presented? [These results are limited and must be treated with caution, but there is sufficient evidence to suggest that the communicative roles of gestures in M3C are underplayed and deserve greater research attention.]2. Communication in Multimodal SimulationsIn simulations, knowledge building typically comes about through hypothesis testing and decision-making. The task requires an integration of the modalities, and the interactions usually involve teachers, students and the computing systems. Hence, knowledge is distributed between these participants and communicated through their interactions. The computer has to manage the simulation environmentbut also support these interactions in ways that providean implicit framework for developing conceptualization and for reflective discussion.A collaborative project undertaken with the M etropolitan Police illustrates these design issues. It concerned the training of Senior Police Officers in the tactical and strategic management of large incidents or events, such as demonstrations/marches where public order may be at risk. The computer has to present a visual scenario, namely a digitized map of central London, on which the trainer can mark the designated route of a march, the group icons of demonstrators (typically fifty groups of forty) members, and significant buildings that might attract unwelcome attention en route. In brief, the computing system hasto enable trainers to design different scenarios, in different locations, and of different sizes and complexities to suit the training objectives.The computer treats the crowd icons as agents with autonomous behaviours operating as a probabilistic network for each group, which allows behaviours to escalate and de-escalate in plausible ways, dependingon what the groups sense: e.g. the state of adjacent groups, the tactics of nearby police groups, the presence of hostile groups, and ‘significant’ buildings. Their behaviours are recalculated every 15 seconds and determine the behavioural state of each group as the demonstration proceeds. The groups march on the route in pseudo real-time but can be wayward, e.g.ifthe march slows then groups become congested and unrest is more likely to occur: if the pace is uneven and gaps appear, break-out is more likely. The trainee hasto ensure the groups are able to exercise their right to demonstrate, but this aim can be disturbed by hostile groups (black icons) placed by the trainer which can gravitate on the map from their entry points, e.g. Tube Stations, towards the march.For their part, trainees decide on the number, type and placing of police units (blue icons) and resources. These can navigate the map in real-time when given a destination, and can report on their status, position, and the status of surrounding crowd and hostile groups. These low level monitoring behaviours are carried out autonomously, but tactical and strategic actions are required from the trainee to control the march/demonstration in response to incidents and other contingencies which arise. These operational instructions are communicated by radio to a facilitator who completes the text templates that go to named unit(s) for action, and are then displayed as text on the computer screen (in bold) in a communication log. Afull range of tactical commands are at the disposal of trainees. The units carry out these operations and give (computer generated) reports. The computer acts as referee, determining the consequences from its rule set (see [2] and [3]). The simulation operates under time-line control and keeps full records so that the simulation can be reconstituted by the trainer for any indicated time and, if appropriate, can be re-run under different tactics to deal with a particular incident. So the simulation proceeds dynamically taking two-three hours.Several design issues are noteworthy. For example, the nature of the task and the interactions require an integration of modalities (visual, text, speech). Also, the system had to be dynamically adaptive,e.g. the trainer could introduce more hostile groups, crowd behaviours if a latent weakness in a trainee’s tactics needed to be tested. And the system built-up frameworks to support critical discussion at the tactical level (was a tactic appropriate, timely in its response, adequately resourced, and properly prioritized?), and also at the strategic level (i.e. management of march, deployment of resources, treatment of hostile groups, information gathering)? The experience was well received by both trainers and trainees, and will be discussed in more detail at the Workshop.References[1] Adams, J, Rogers, B, Hayne, S, Nash, J, and Leifer,J; 2005.
