Current HAL Research Projects Research in the Humans and Automation Lab (HAL) focuses on the multifaceted interactions of human and computer decision-making in complex sociotechnical systems. • Time-Sensitive Operations for Distributed Teams • Measurement of Display Complexity • Collaborative Human Computer Decision Making • Integrated Sensor Decision Support • Reduced Manning for Unmanned Vehicle Teams • Single Operator Control of Multiple Unmanned Aerial Vehicles
Supervisory Control & Teams Supporting Supervisors of Teams of HSC Operators Supporting the Control of Teams of Heterogeneous Unmanned Vehicles
Inverting Current UAV Control Schemes • How do operators manage multiple supervisory control processes? • What effects do human performance limitations have on the overall system? • Reduced Manning • Combining Shadow positions • Multiple UV control for a single operator • Distributed control Multi-Modal Watch Station
Collaborative Decision Making • Tomahawk Strike Planning: missions and missiles • Determine how humans and computer optimization algorithmscan complement each other • Cognitive strategies
Aiding Human-Computer Path Planning • Decision Support for Planetary Exploration • Astronaut traversal replanning task • Path replanning with increasingly complex constraints • Affect of level of automated decision support
Goal of this Research Project To identify or develop technologies to facilitate collaborative decision-making in the time-sensitive targeting task domain
Teamwork in Network-Centric Operations • Highly connected operators, often working remotely • Heavy reliance on commercially available collaboration technologies • email • instant messaging (‘chat’) • video & desktop conferencing
Benefits of Collaboration Technologies • Facilitate collaboration with remote colleagues • Facilitate sharing of and access to digital media during group work (in both co-located and distributed settings) • Provide opportunity and support for casual interactions • Promote ad hoc collaboration & communication • Enhance team cohesion
Disadvantages of Collaboration Technologies • Require explicit effort to access / share information • implicit or more subtle communication / interaction is often missing • lack of non-verbal cues • Typically convey information about completed activities, ongoing progress/status information is also important: • Has anyone seen my request for help? • Is someone working on the problem? What’s their status? • Associated costs with using collaboration technologies: • distraction • time & mental effort of asking for or sharing information
Enhancing Teamwork in Non-Military Domains • Research in the CSCW domain has been focused on providing technological support for teamwork in many collaborative settings: • corporate, educational, research • Reviews of the CSCW literature has revealed common threads across many new approaches to CTs: • Minimizing overhead costs of sharing information about remote collaborators • Increased use of automation to help provide this information • Many approaches are aimed at supporting the shared activity process
Virtual School Project Timeline (Carroll et al., 2003) IBM’s Activity Explorer (Millen et al., 2005) Supporting the Shared Activity Process • Focused on providing team member’s activity awareness (Carroll et al., 2003): • awareness of project work that supports group performance in complex tasks • implies an awareness of other people’s plans and understandings Project View IM (Scupelli et al., 2005)
Supporting the Shared Activity Process (cont’d) Approaches for supporting activity awareness: • Feedthrough of action • Visibility of action Project View IM (Scupelli et al., 2005) Scupelli, P., Kiesler, S., Fussell, S.R., & Chen, C.

Supporting the Shared Activity Process (cont’d) Approaches for supporting activity awareness: • Feedthrough of action • Visibility of action • Important to situate this information within the context of the shared activity process Virtual School Project Timeline (Carroll et al., 2003) Carroll, J.M., Neale, D.C., Isenhour, P.L., Rosson, M.B. & McCrickard, D.S.

Challenges Introduced by the TST Domain • Determining what constitutes relevant activities when ‘shared objects’ are not necessarily ‘files’ • Reducing the cost of providing activity-related information to team members • Balancing awareness and information overload • Balancing individual performance and team performance
Methodology for Developing Activity Awareness Support for Collaborative TST Operations • Develop representative collaborative TST task scenario • Conduct task analysis on scenario to develop collaborative technology requirements, focusing on the shared activity process • Develop initial team display designs for collaborative TST scenario incorporating CT requirements • Implement team display designs • Develop evaluation protocol and teamwork metrics for evaluation of team displays • Design and build team testing environment • Evaluate team displays • Iterate team display designs based on study results
Representative Task Scenario: GTT Task Generalized Team TST (GTT) Task • A convoy is scheduled to passthrough a hostile region • Team of UAV operators must protect convoy until convoy exits region • Stakeholders: • Convoy • UAV Operations Team + UAVs • Strike Team • Intelligence • Enemy

Activity Awareness Requirements for the GTT Task Scenario • Types of intra-team shared activity information • relevance to current tasks / team member • available task resources • priority of current task activity • operators’ availability (progress, workload, tasking availability) • operators’ interruptibility (status, cognitive availability) • This information helps team members address the questions: • when / how can I help somebody else? • when / how can I be helped? • how do my actions impact others’ activities?
Relevant Activity Awareness Information is Role Dependent • COM and mCDR need status and workload information of the UAV Ops to ensure individuals and team are not overwhelmed • mCDR can help UAV Ops prioritize task activities or request support from external resources • helps COM distributed TST and BDA assignments among UAV Ops • UAV Ops need operator & resource availability and interruptibility information • helps minimize disruptions when someone is involved in critical tasking • helps operators know who can feasibly help them, or who might need their help
