Design Criteria Low Cost User Friendly Low Power Can be Replicated Low Maintenance
Conceptual Designs - Software Linux (Ubuntu) MDM (Multi-seat Display Manager) GDM (GNOME Display Manager) Userful (Commercial Software)
Multi-seat Display Manager Specifically designed for multiple seats Runs nested, virtual sessions Pros Free Currently being used in Tanzania Cons Less support Easy for users to make mistakes
GNOME Display Manager Current Ubuntu configuration Multiple user system Pros Inexpensive Common display manager Cons Not currently used in Tanzania Not designed for more than two seats
Userful Commercial software Designed for up to 10 seats Pros It does everything! Solves audio problem Solves automation problem Cons Cannot alter configuration files More expensive (roughly 35% per seat)
Conceptual Designs - Hardware Automated USB Hub Device will perform automatic registration for Keyboard, Mouse and Sound May require additional custom software Will not be needed with Userful solution
AUDRI - Automatic USB Device Registration Interface
Cost Analysis - Per Seat Software USB audio USB hub Enclosure Total Software USB hub with audio Total = $69 MDMUserful - Free - $20 - $5 = $45
Cost Savings Comparing MDM and Userful $24 saved per seat x 6 seats per school = $144 3 schools x $144 = $432 If implemented in 100 schools (600 seats) Savings of $14,400
