the evolution of the computer on the farm

The evolution of the computer on the farm

The best place to start, is with:

problems

Problems:

Heavy

Awkward to use

Not “rugged” enough!

slide6

To overcome problems of the portable computer, “ruggedized” portables were developed with various data collection tools.

problems9

Problems:

Expensive!

Often limited capacity/capability

Screen usually downsized

Heavier than user “liked”

problems12

Problems:

Really limited in capabilities

Keyboard became too small for users

Not small enough to be truly “bound” to the user

to overcome keyboard problems increase screen size improve data entry pen based computers developed

To overcome keyboard problems, increase screen size, improve data entry, pen based computers developed

evaluation

Evaluation:

Very rugged

User like

Powerful (386/486/Pentium)

Big display

Pen writing somewhat awkward

A little big to be “bound” to the user

slide16

To improve the usefulness of the computer, size was decreased, and less flexible pen writing recognition adopted

evaluation19

Evaluation:

Computer is tightly bound to the user

Most software well “linked” to desktop PC

Light weight, battery life very long

Programmable

pen computing works best if

Pen ComputingWorks bestif.....

Used mainly as reader of data, not collector of data

Think of “shopping lists” when designing software for the pen environment

pen computing works best if22

Pen ComputingWorks bestif.....

Limited CPU is not “stressed” into intense numeric calculations

Most input is check boxes, buttons, or pick lists

Limit “freeform” input to a minimum

examples

Examples:

Cow/Calf herd management.

“Cowboy” has a PalmPilot loaded with herd data. As they ride around the herd, all breeding/calving information is at their fingertips.

examples25

Examples:

Operations:

All maintenance records for equipment and building is recorded in a central database, that is downloaded into the PalmPilots. Maintenance crews have history in their pockets.

examples26

Examples:

Swine Farrowing barns:

As piglets are born, their weights, and sex are recorded, then uploaded to a central database.

examples27

Examples:

DNR Compliance:

Location of wells, lagoons, spray fields, and other disposal sites have been geolocated, and maps downloaded so manure wagon operators know where to operate
