The Mobile Application Space CS 160 Discussion Section January 31, 2006

Agenda  Mobile application examples  Mobile input techniques  Mobile output techniques

Mobile Device Case Studies (current applications)

Agriculture  Problem: Pistachios must go from tree to huller quickly to maximize quality Use PDAs to scan barcodes on individual bins and to update data records  Problem: In managing artificial insemination of cattle, it’s essential to know where samples come from Record activities on a custom mobile application, rather than on paper forms (save 25% on data management costs)

Education  Problem: School administrators need access to student information outside of the office and classroom (e.g., roaming the halls or at events) Mobile access to schedules, contact and medical information  Problem: Laptop PCs take up too much space in lab and create a barrier between teachers and students in the classroom PDAs with special sensors as lab tools and data records Interactive surveys in the classroom

Law Enforcement  Problem: It’s inefficient for police officers to conduct vehicle and person checks over walkie- talkies Allow queries from mobile devices  Problem: Analysis of potential racial profiling requires specific data about police encounters Give officers a questionnaire to fill out every time they make a stop

Health Care  Problem: Paper medical records are difficult to manage and maintain Provide mobile devices for the electronic dictation and review of medical records  Problem: Thousands of deaths each year are caused by administration of the wrong medication Scan medication upon administration and electronically for a valid physician order

Real Estate  Problem: Real estate agents are frequently showing property to clients and need to access information back at the office Provide mobile access to property and customer profile information

Transportation  Problem: Truckers need up-to-date information about pickup and delivery destinations, especially with increasingly real-time shipping needs Combine GPS tracking and navigation with automated dispatching  Problem: Dispatching taxi cabs to the closest customers is a difficult process Use GPS-enabled mobile devices to track and send jobs to a fleet of taxis
