- Ein interessantes Interview mit Luca Passani dem Entwickler hinter wurfl, der freien Endgeräte Datenbank:
auf mobileopen.org

- Dev Tips zu mobilen Widgets oder generell mobilen Websites von Opara:

GENERAL

- Keep the user interface simple

- Keep the technical solution simple

NETWORK

- Optimize client/server network communication

- Minimize amount of data transferred
- prefer JSON over XML

- Batch requests to the server, use HTTP pipelining

- Let the server return HTTP 304 when data has not been updated on
server

DOM AND DATASTRUCTURES

- Keep your DOM short, simple and shallow

- Store data in Javascript variables and create DOM elements only for
the current view.

- Avoid hiding large number of elements with CSS display: none;
instead remove the elements from the DOM and store data in
Javascript variables

PAGE LAYOUT

- Avoid reflows. Examples of things that may cause reflows:

- Change of class names

- Change of element dimensions and positions

- Insertions of elements into the DOM; insert completed
document fragments; don’t add element by element

USEABILITY

- Follow the steps of user centered design:

- Understand the needs of your users

- Understand the environment where the widget will be used
- device characteristics
- context where the widget will be used, e.g. mobility, light,
attention

- Create scenarios and use-cases

- Wireframes, prototype and test

- Inputing data on mobile devices is generally difficult, let the user
make selections instead of typing

- Desktop services to be presented as mobile widgets must be
redesigned to work

- Use CSS style sheets to adapt the visual presentation of the widget
for devices with different characteristics
