Symbian DevZone - Siemens SX1 Developer Opportunities
by Richard Bloor, June 30, 2003

The transition of the mobile phone from dumb to smart has also been accompanied by some interesting rethinking of the tried and true phone design paradigms. While the Nokia 7650 and Nokia 3650 bent the rules the Siemens SX1 breaks them completely but at the same time opens some interesting possibilities for application control. - Printer Friendly Version

Siemens SX1 - New keyboard layout offers new control options
Message from Sponsor

Series 60, with its contacts database and call logging features means that dialing a number from the keypad should now be an infrequent activity. As a result it is likely that the keyboard on a Series 60 phone will be used far more for text entry than number dialing. The control of Series 60 is primarily through the joystick and soft menu keys, which almost certainly influenced the design of the Nokia 7650 with its shy little hideaway keyboard. As we have already noted in an earlier article (reference) the Nokia 3650 keyboard was designed around the Series 60 navigation buttons that resulted in the circular numeric keypad. Siemens with its SX1 have gone even further and thrown away the rulebook to create a radical new layout that sees the keyboard moved up to sit either side of the phone’s display.

Siemens SX1

According to Oliver "Oz" Zechlin, Global Marketing Manager for Application and Services for smartphones the SX1 is positioned as an aspirational flagship product within Siemens mobile phone portfolio. "It is the very first Siemens phone to combine built-in camera, video player/recorder, 65k TFT color display, MP3 player and FM radio with an unique natural loudspeaker in one," Oliver said. "We hope that the SX1 will be a fashionable object of desire. It's aura is powerful and we believe that in design terms SX1 is outstanding and offers a highly innovative side-key concept which increases the speed and convenience of use."

Creating a new design has its pitfalls, the obvious one being that of user acceptance. New keyboard designs, particularly given the experience in the PC world where several attempts have been made to offer better alternatives to the QWERTY keyboard, have been largely unsuccessful in the past. Siemens are aware of this as a possible issue. "We have conducted extensive tests on the user interface," Oliver said. "The first thing our tests illustrated was that people are curious about the design and they want to handle SX1 to try it out. Our test results have shown that people easily get used to the new concept and there is a high acceptance for the new keypad design. Of course not everyone likes the design but overall we believe we have achieved that all important ease of use for our customers."

The side keys also open up some new possibilities for developers. The majority of the keys are adjacent to the screen creating the possibility of using the number keys in a direct way to control applications something which would have been impossible with a standard keyboard. This rather obvious usage unsurprisingly has not been lost on Siemens.

To ensure that side key controls are not as obscure as standard keyboard shortcuts there is an obvious need to incorporate some form of label into the screen display. Doing so however would obscure a significant portion of the screen, reducing the space available for the application, not necessarily a desirable thing to do on the 176 x 208 Series 60 screen (the SX1 screen is actually 176 x 220 as Siemens have added a permanent status bar to the standard Series 60 layout). Siemens addressed this issue by devising three alternative models for labeling the keys.

The first is permanently displayed labels. This model has the labels always displayed, with the application space being narrowed to the center of the screen. As the active application space is reduced this approach will work best where the key label information integrates with the application. This is the approach Siemens has taken in providing controls for the SX1’s FM radio where the side keys provide access to preset radio stations, in a similar fashion to the preset buttons on a conventional radio.

The second approach is to have a temporary layer that displays the key labels, activated by the user. In this model the labels obscure the underlying screen temporarily while they are displayed. This approach will allow the application to continue to use the full screen but provide the user with the key labels when they need them, either while they are learning the shortcuts or when reminding themselves of ones they don’t use that frequently. This option reduces the number of available shortcut keys as one will need to be reserved to show the labels. Siemens are recommending that the activation key is the 8 key. The final option is to use a semi-transparent layer where the key labels permanently overlay the screen but the application is still visible below. The key label background would need to be visually identifiable and clearly associated with the label so as to ensure that the application background and key label were not confused by the user. This option may well be the hardest to implement because of the graphic design needed to ensure that the application in background and label in the foreground do not clash, otherwise neither key label or the underlying application will be readable.

The design of the SX1 also means that where keys need to be labeled the application will not be able to use all 10 number keys for shortcuts. This is due to the fact that the 1, 2, 6 and 7 keys are adjacent to or above the status panel at the top of the screen. However for games, which can use the whole screen (except for Siemens’ own status panel) only the 1 and 6 keys are adjacent to the status information.

Creation of the key labels will be a manual coding exercise as there are no additional APIs to create button labels.

"At first sight, I thought that the arrangement of the sidekeys was just a unique part of the product design." Said David Mannl, who works as a freelance consultant on Series 60 interface design. "But when I started to work on concept interfaces and applications for the SX1 I realized, that the use of the sidekeys as hotkeys gives me new possibilities for creating applications that otherwise would have been to difficult for the user to navigate through. The arrangement of the sidekeys allows me to design applications with a much more effective user experience, as there is a strong visual connection between screen content and user interaction."

The design of the SX1 offers developers the flexibility to add additional control to their applications that will be easily accessible to the user. It will be interesting to see how widely this option is used. Games developers are likely to be the main users as games often use the number keys to provide game control. Also games probably won’t need to use the labels extensively (they don’t at the moment) meaning that all 10 keys could be used and little additional development effort will be required, particularly if the game already includes a key mapping function. The use of the side keys to control other types of application will in many ways be a barometer of the SX1 popularity as effective use of the side keys will require a slightly different approach to the applications interface design. They do however offer the possibility of improving the user experience by making regularly used functions more accessible.

One of the strengths of Series 60 is its ability to provide the consumer choice in hardware while providing a common platform for developers. The SX1 will be able to run Series 60 applications without any need to consider using the side keys but developers now have an option that could be used to improve their applications usability. It will be interesting to see how many rise to the challenge.

Siemens are planning to publish a white paper describing the use of the side keys in more detail on their developer web site (http://www.siemens-mobile.com/developer) by the end of July

Cool, das ist genau das, was ich im Thread

SX1 Tastatur Praxistauglich

meinte: es eröffnet sich die Möglichkeit einer sehr effektiven Steuerung, wenn das Konzept konsequent und intelligent umgesetzt wird.
Betrachtet man das ganze oberflächlich, so kommt dabei oft das bekannte "iiih, die Tastatur des SX1 ist ja total scheisse" heraus. Denkt man über dieses Konzept etwas nach, so kommt man schnell auf die Möglichkeiten, die in diesem Artikel dargestellt werden.
Manchmal ist es sinnvoll, etwas Arbeit aufzuwenden, und neues zu lernen, um schliesslich viel Arbeit zu sparen oder gewisse Dinge überhaupt erst möglich zu machen.

Da hast du völlig recht! :top:

Threads zusammengeführt.

ich denke auch, dass es kein problem ist, mit zwei daumen zu schreiben.
ich habe allerdings festgestellt, dass sehr viele frauen dazu neigen, mit einer hand zu schreiben, während männer mit zwei händen schreiben.
(ich hatte mal in meinem bekanntenkreis gezählt...fast 90% der frauen schreiben nur mit einer hand)

demnach ist das sx1 wohl "frauenfeindlich"

Nicht nur deswegen -

"Machomodus an":

Es ist von den ganzen Features her einfach zu komplex für das schwache Geschlecht!

"Machomodus aus"

Gruss, marks

Also für mich ist die Tastatur definitiv nicht Praxistauglich, ich möchte ein Handy möglichst schnell mit einer Hand bedienen können und eine Telefonnummer mit dieser Tastatur einhändig einzugeben ist eine Qual wie ich selber auf der Cebit testen konnte. Naja ich gehöre wahrscheinlich nicht zur Siemens Wunschkundschaft die eine Handy hauptsächlich zum SMS schreiben und andere Fun Dinge benutzen. Auch wenn sich mit der Tastatur noch soviele Möglichkeiten der Belegung rund ums Display anbieten, es meistens mit zwei Händen bedienen zu müssen macht es Praxisuntauglich.

wikki
also das frauen überwiegend mit nur einer hand schreibt kann ich auch nur bestätigen-gibts da vielleicht ne (online)umfrage die das bestätigt?!
ist echt schon irgendwie komisch-wie kommt das,dass man das geschlechterspezifisch differenzieren kann...

ciao OLI!!
