Operational ConceptsOperational Concepts• Email and Instant

Messenger are static in space and time

• Spatial Note– Digital and virtual– Dynamic in time and

space– Similar to a human

reminder

• Utilization of mobile devices and GPS

System Requirements (1)System Requirements (1)• What do we need to create it?

– Mobile client• Pocket PC or Pocket PC Phone edition• Wireless Network Access: WiFi, cell phone

data carrier

– Server• Web service• SQL server

System Requirements (2)System Requirements (2)• What does it do for us?

– Leave virtual notes for yourself and others that are location based

– Notes can be used as reminders, greetings, and much more

– Keep a personalized list of locations for fast access and ease of use

• Location Awareness– Abstraction for location based services. Keeps

Spacial Note adaptable to future location based technologies

• Client– Holds other components together

• Server– Stores notes and information about users.

Communicates with client via webservices.

Lifecycle plan (1)Lifecycle plan (1)• Schedule

– Phase 1: preparation– Phase 2: intensive development– Phase 3: finalization

• Task assignment– Server development/ Database – Dung– Client development / Graphics – Chris– Client development / Location API – Thinh

Lifecycle Plan (2)Lifecycle Plan (2)

Lifecycle Plan (3)Lifecycle Plan (3)• Customers:

– College students– Young children– Businessmen– Customer services– Everyone

• Support:– Our team– School’s database– PDA manufacturers

FeasibilityFeasibility• The structure is simple.• Hardware support & simulator are

available.• Many people will love it.• Some security issues and risks might

arise.
