Context-Aware Notification for Mobile Police Officers

Abstract

To minimize unwanted interruption and information overload during surveillance, mobile police officers need to be supported by a mobile, contextaware notification system. This system adapts message presentation to message priority and context of use. A prototype is designed and evaluated in a simulated surveillance task, requiring users to attend to videos while handling messages on a mobile device. Adaptive notification led to better performance and less intrusive messages than non-adaptive notification, especially in high workload situations. Subjective judgments showed a positive user experience with the adaptive notification system. These empirical findings are used to improve the design of mobile notification support systems for police officers.

Balancing Awareness and Interruption in Mobile Patrol using Context-Aware Notification

“…the sound conveys the priority of the message (Streefkerk et al, 2007). Presentation timing is either direct (when message becomes available) or postponed (until a change in officer activity).…”

Context-Aware Team Task Allocation to Support Mobile Police Surveillance

“…"John and Mary can handle the burglary incident best"). As in previous work [4], the presentation style of these messages (information density and auditory salience) is adapted to limit unwanted interruptions. The prototype uses the following decision rules:…”

“…In this study, a support system is designed that provides advice on task allocation (which team member can handle which incident best) based on officer availability, task priority and officer proximity to the incident location. Selected team members are notified using appropriate notification styles (timing and presentation of notifications) to limit interruptiveness of notifications [4]. This team task allocation support is evaluated in a surveillance task with police teams, addressing the following questions: 1) how can user availability, task priority and proximity be used for team task allocation support and 2) what are the effects of this support on police team task performance, workload and subjective judgments?…”

Usability of an Adaptive Computer Assistant that Improves Self-care and Health Literacy of Older Adults

“…In addition, given that the adaptive computer assistant's feedback style is designed for the patient's health situation, the adaptive assistant might lead to a higher level of usability [16]. Because the fixed assistant will continuously keep coaching, advising and educating the subjects, it might lead to a higher level of diabetes knowledge.…”
