  • Figure 3 shows steps that are passed in executing the method according to an embodiment of the invention.
  • An HDML or WML document may contain several interactive 'forms' with data to be submitted to origin servers.

  • $showlf allows the user to see information which is familiar as a radio button or checkbox; one of the following two options, clearly indicating selection:
  • Selecting any of the enumerated-value options on the list should perform a 'task' in HDML, which should swap or rotate the variables, and then go back to the same card. By repeatedly selecting the same option, each of the values is visited in rotation.
  • the list of enumerated options should be followed by an option or soft-key setting to allow the user to exit the card offering the choices, and move on to another. This is important as all of the enumerated options merely change the settings and return to the same page.
  • a submission to the origin server might occur with a link like the following:
  • HDML devices typically return values for all of their unique variables, which may be on or off, and can hold only one value under each name.
  • embodiments of this invention can provide an almost perfect emulation of an HTML checkbox by placing both the HTML input name and value into the submit value.
  • the fragment '%3D' represents an equals sign -' and remains as such if passed back to the origin server as $(lf:noesc) which prevents the browser device from using the '%' notation for the variable $lf.
  • icon 62 is a cross
  • icon 73 is a tick
  • the methods presented here are for adding selection of multiple options from lists in a way not normally supported on the devices in question such as mobile phones.
  • the values for the options should be enumerated by a designer in advance, each of the options having two or more possible values.
  • the user is able to select a value for each option from the enumerated list, to review their choices, and to submit these to a server which is unaware of the method described here (indeed, which may be unaware of the capabilities and limitations of the device submitting the information).
  • Embodiments of this invention are therefore particularly useful when attempting to display options normally seen in HTML web pages, on the less-capable mobile browsers.

Abstract

L'invention concerne un procédé et un appareil permettant d'améliorer automatiquement l'interactivité du navigateur. Les modes de réalisation de l'invention concernent l'affichage d'options normalement visibles sur les pages Web HTML, au moyen de navigateurs mobiles moins performants. En utilisant les files d'attente circulaires pour stocker les variables correspondant aux valeurs potentielles d'options sélectionnables, l'utilisateur peut parcourir les différentes options avant de faire son choix. Ce système est particulièrement utile pour représenter l'équivalent des cases à cocher HTML ainsi que les listes à sélection multiples telles que celles que l'on rencontre sur les sites Web interactifs en langage de balisage mobile.
