  1. USING CONTEXT-AWARE COMPUTING TO SUPPORT ENGINEERING COLLABORATION Dr Zeeshan Aziz Center for Innovative Collaborative Engineering, Loughborough University, UK.

  2. Presentation Outline • Need for Context-Awareness in Collaborative Working • Service Delivery Framework • Case studies of Service Delivery Framework Implementation • Transportation • Learning Environment • Construction Site Operations

  3. Issues in Collaborative Working

  4. Reasons for Contractor Re-Work (Source: ICE, 1998)

  5. Issues in Collaborative Working • “the cost of construction can be reduced by 25% through the efficient transfer of information”. ICE Publication • “BP Exploration estimates that reducing the time needed to locate and acquire information would increase efficiency and result in annual savings of between US$10 million and US$20 million”

  6. Project Collaboration Management

  7. Site-Based Personnel The Problem Q.S. Contractor Project Collaboration Client Eng. Arch.

  8. Collaborative Needs of Mobile Workers • The need to address the collaboration needs of mobile workers have long been understood • To exploit the potential of emerging mobile communication technologies, many recent research projects have focused on the application of these technologies to support mobile engineers

  9. Limitations of the Existing Approaches • Existing mobile ICT deployments see support for mobile engineers as a “simple” delivery of static information using asynchronous or synchronous communications • There is no consideration of user context and dynamic conditions of a project or changing user requirements

  10. CONTEXT-AWARENESS Need for Context-Awareness THE DIGITAL WORLD THE REAL WORLD

  11. Key Benefits of Context Aware Information Delivery • Reduction in distractions related to the volume and level of information; • Improved Usability via reduced user interaction; • Improved decision making.

  12. Feedback Decision Making Environment Context Awareness Performance Perception Interpretation Projection Improved Decision Making via Context Awareness • Perception – the basic perception of important information • Comprehension – the integration of multiple pieces of information and a determination of their relevance to the person’s goals • Projection – the ability to forecast future situation events and dynamics

  35. Rail Timetables

  36. Access to Time-table web-service – Details of the station of origin is automatically captured

  37. The Findings • Overall Positive Response • Ergonomic Issues - “Not enough hands” • The wow factor – “the shiny new gadget” • Demands on user attention

  38. Context-aware data delivery in an Education Pilot

  39. Key objective: Context-Aware Access to Learning Material • Pushing class notes / presentations • Questionnaires / Surveys • Delivery of applications Location Specific ( x2,y2,z2) ( x1,y1,z1) Device & User Specific Time Specific
