    Sentient Computing For Innovation Sentient Computing For Innovation Presentation Transcript

    • Mobisys Seminar 02.12.08 Sentient Computing for Innovation Understanding Organisational Behaviour through Pervasive Technology Irene Lopez de Vallejo, PhD Candidate i.vallejo@ucl.ac.uk The Bartlett, Faculty of the Built Environment UCL University College London
    • Mobisys Seminar 02.12.08 Initial considerations • Sentient computing is the proposition that applications can be made more responsive and useful by observing and reacting to the physical world Andy Hopper, The Royal Society Clifford Paterson Lecture,1999 – Built Environment – Inhabitants • Innovation key form of organisational knowledge creation, organisations create and define problems and actively develop new knowledge to solve them Nonaka 1994 – Individual and collective employees expertise – Building design
    • Mobisys Seminar 02.12.08 Key question • How can location tracking systems contribute to the understanding of informal face-to-face interaction in the workplace?
    • Mobisys Seminar 02.12.08 Interaction, Knowledge Management and Innovation • Physical interaction key issues for today’s firms • To create and transfer knowledge individuals need to interact • Informal face-to-face interactions essential for – Trust building – Flow of ideas – Social relationships original context on the page: www.ikiw.org/category/interdisciplinary/
    • Mobisys Seminar 02.12.08 The other side of the coin: Solo work • Get work done! • Concentration vs communication – Fluctuating desired levels of privacy and interaction – Individual creativity • Interruptions – Stress levels – Time famine • Paradox of knowledge management – Best transfers serendipitous, personal and private – Best insights need periods of intense reflection combined exposure
    • Mobisys Seminar 02.12.08 Organisational and Design considerations • Work context intense, fast, novel and collaborative • Create processes, structures and environments that allow and encourage individuals to interact to promote informal knowledge transfer • Face-to-face interaction is a mechanism • Design a strategic tool to support emergent organisational forms – Adequate time and space for interaction – Open spaces are more favourable
    • Mobisys Seminar 02.12.08 Pervasive technologies to measure interaction • Current methods – Static picture – Self assesment and observations • A new tool – Indoor location tracking technologies – Dynamic and long term view • A real life deployment: – Ultra-wideband RF technology: Nationwide pilot project
    • Mobisys Seminar 02.12.08 Pervasive technologies to measure interaction If you cannot measure it, you cannot manage it • Current methods – Static picture – Self assessments and observations • A new tool – Indoor location tracking technologies – Dynamic and long term view • A real life deployment: – Ultra-wideband RF technology – Nationwide pilot project
    • Mobisys Seminar 02.12.08 A New Method to study interaction: background • L-T system calculate position accuracy 15 cm, 48% time • Spatial and social challenges • Raw location dataset – Noise – Assumptions – Definitions – Mathematical Manipulation
    • Mobisys Seminar 02.12.08 A New Method to study interaction: background Can interaction be measured, understood and managed? • L-T system calculate position accuracy 15 cm, 48% time • Spatial and social challenges • Raw location dataset – Noise – Assumptions – Definitions – Mathematical Manipulation
    • Mobisys Seminar 02.12.08 Dealing with noise • No noise free location technology • Kalman filter • Delete all XYZ = 0 • Delete entries Z < 0.5, > 2 metres • Delete entries negative X and Y data points
    • Mobisys Seminar 02.12.08 Preliminary assumptions • Set of events that exclude each other • Each event has two states: ON and OFF • Time line – Organisation • Spatial setting – Deployment area
    • Mobisys Seminar 02.12.08 Definitions: events • Solo • Interaction • Other • Threshold value
    • Mobisys Seminar 02.12.08 Definitions: temporal factors • Occurrence • Recurrence • Duration • Interval • Cycle • Rhythms
    • Mobisys Seminar 02.12.08 Definitions: Spatial factors • Cartesian coordinates • Pre-allocarted zones • Configuration of office space
    • Mobisys Seminar 02.12.08 Summary defintions and unit of analysis Behaviour Measures SOLO INTERACTION OTHER PERSONAL  1 individual  2,3,4,5 and 6 individuals  Outside SPACE  Aggregation of workforce  Aggregation of workforce deployment  No trespassing personal  Overlapping of personal  Aggregation bubble of 1.5 feet radius or bubbles for a minimum of workforce overlapping of personal duration threshold value bubbles of under 30 seconds of 30 seconds TEMPORAL  Occurrence, recurrence, duration, period or cycle, interval and rhythm. FACTORS LOCATION  Cartesian coordinates (XYZ) FACTORS  Pre-allocated zones1  Configuration of office space
