Research Description
Throughout 80’s and 90’s, my research focus was on theories, algorithms, architectures and tools for building real-time systems.
Those decades saw great advances in technologies for building time-critical systems from commodity components and validating
rigorously their timing behavior. PERTS (Prototyping Environment for Real-Time Systems) built by my students and me in the
mid-90's is a part of our contribution. This system of schedulers and tools puts theorems and algorithms for scheduling, resource
management, and validation into a ready-for-use form so that developers may validate, simulate and evaluate design alternatives of
time-critical systems. PERTS was subsequently commercialized. We also developed the underlying principle of an open architecture
for real-time applications. The architecture makes it possible to tune and validate in an open environment the timing behavior of a
real-time component independently and thus enables independently developed real-time and non-real-time applications to run
together. Our approach was convincingly demonstrated by Windows and Linux prototypes of kernel-level CPU and disk bandwidth
reservations.
When I rst joined Institute of Information Science, my research focused on system architecture, components, platforms and tools
for building easy to use, customizable and safe user-centric automation and assistive devices and systems devices at low-cost. Some
of the devices aim to enhance the quality of life and self-reliance of users, especially elderly individuals. Other devices can serve as
point-of-care or automation tools for use at home or within care-providing institutions. Publications on this work and links to open
source software prototypes can be found at the SISARL homepage http://sisarl.iis.sinica.edu.tw.
My recent work concerns technologies for disaster preparedness and response. This work was supported by the thematic projects
OpenISDM(Open Information Systems for Disaster Management) and DRBoaST (Disaster Resilience through Big open Data and
Smart Things) in the Academia Sinica Sustainability Science Research Program. The major thrust of the OpenISDM project was
toward providing a framework for building open and sustainable disaster management information systems. Building blocks of the
framework include trustworthy information brokerage services for responsive information access during emergencies and methods
and tools for synergetic use of data from human sensors and physical sensors. Proof of concept prototypes and publications can be
found at the OpenISDM homepage http://openisdm.iis. sinica.edu.tw.
Project DRBoaST further emphasizes the generation and use of data and smart things. Signi cant contributions of this work include
active devices, mobile applications and services/systems that can automatically process alerts from authorized senders and initiate
location-speci c preparedness and response actions to reduce risks when disasters strike. Our prototypes have demonstrated the
feasibility of active smart devices/applications and the effectiveness of active emergency response systems containing them. To
enable their pervasive use in smart buildings and environments, we designed and built a platform called the Building/environment
Data and Information system (BeDIS). Structured as a fog, BeDIS is scalable and responsive under overload. When triggered by a
disaster/emergency alert from responsible government agencies or the building safety system, BeDIS functions as a system of
micro data servers for delivering location- and situation-speci c emergency response instructions to people and decision support
data to active devices and applications. During normal times, it functions as an indoor positioning system, enabling people to
locate themselves and navigate amidst dense crowd and moving objects indoors via their mobile phones. BeDIS also support
applications and services for locating objects and people indoors and tracking their movements with location accuracy of 3-5 m or
6-10 m and nominal response time of 2-3 seconds. BeDIS is being productized along with families of indoor positioning and indoor
navigation and real-time object tracking and geo-fence applications. These future products are undergoing eld trials in which their
e ectiveness and usability are assessed by targeted end users in hospitals and elderly care facilities.
