Introduction
The analysis of the Palm Banking client (see analysis report) is further developed in this second report and a redesigned system is proposed, addressing
most user interface problems discovered in the prototype. Further suggestions
from real Piloteers influenced the iterative design process.
The user interface (UI) design philosophy is to create a fast application as well
as to match use frequency and accessibility, which includes the ability to:
• Execute key commands quickly.
• Navigate to key screens quickly.
• Find key data quickly.
The menu-centric navigation is replaced by functional connections, where the
user first selects an object and then applies an appropriate action. This proposal
is in contrast to the previous behavior, where certain operations required a list
selection before the corresponding data was presented. With the new approach
less or equal stylus tabs are necessary to perform most functions, resulting in a
grand usability enhancement.
This paper discusses only the “front-end” of the Palm Banking system. I assume that the technical implementation is feasible like the secure, wireless
communication for domestic customers. The analysis of the existing mock-ups
proofed as a good starting point for gathering requirements. Additional alternatives have been considered from early feedback and studying the built-in Palm
software.
