Review GSM-phone Siemens SX1. Text input test

Review Siemens SX1. Summary>>

An ability to input the text on-the-fly plays a big role for smartphones, since answering an e-mail, typing an URL in the browser or simply answer SMS is vital. The user needs ability for fast and convenient text input.

We’ve selected a group of five volunteers and asked them to type one and the same text. In the first experiment they were typing an e-mail, and SMS in the second one with T9, and SMS without T9 in the third one. The process of text inputting started at once; the appropriate applications were already launched. We gave the volunteers three tries to enter the text, plus the users had ability to familiarize with punctuation marks input technology since this phone was earlier unknown for them.

The volunteers were chosen according to their experience, we had two experienced users (who write SMS often and have Pocket PC with sensor screens) and three newcomers (those who had a few mobile phones and didn’t use smartphones). All users knew English well and use it in their daily life, that’s why we offered them to input the text in English. Typing proper capital or non-capital letters wasn’t required, entering the whole text and keeping the punctuation marks was the only thing that was. Some more testing was made for entering text in Russian; however the results were pretty similar this is why they’re not shown in this review. Average results are shown in the table below, there are some more tables that show results for the same test being made for other devices. We weren’t asking the volunteers to hurry up, the users were typing the text in their usual and common manner.

Example of SMS:

Do you have wholesale customers for mobile phones? We are looking for buyer in Russia. We are exporters of mobile phones based in the UK. Await your news Thanks

Example of e-mail:

The feedback for SX1’s keyboard was different, everyone was pointing out its unusual outlook and unpracticality for fast text input. The users often encountered a fuss while trying to find the right button; this affected the text input speed negatively.

Such keys placement will fit those who didn’t have any experience in working with cellular phones that have “normal” keyboard. We believe that there will not be much of them among the SX1’s consumers. Unfortunately we weren’t unable to provide the volunteers with these devices for a long term in order to see if they can get used to it or no. But I can tell you from my experience that getting used to this keyboard placement is rather hard, and this process lasts for a few weeks. However the text input speed increases after that, but it’s still 2x times slower than if I use “normal” mobiles. This is the main disadvantage for this phone and affects all features. The results speak for themselves, and if you send us your results for the same test – we will be happy to look at them. Perhaps they will be better, but who knows.
