Study shows iPhone on-screen keypad is twice as slow for texting as QWERTY keypad phones

One of the largest complaints posed by new iPhone users is the efficiency of the onscreen keyboard. According to a new study potential iPhone users can now at least quantify that complaint.

User Centric, a usability study group, unveiled the results of its iPhone study today conducted with 20 participants aimed at determining if the iPhone’s touch sensitive onscreen keyboard was as effective as traditional QWERTY keyboard or multitap messaging phones.

The study participants had never used an iPhone and were considered to be heavy text message senders defined as sending at least 15 text messages per week. Out of the twenty participants, ten owned phones with QWERTY keypads and ten owned phones with numeric keypads that used multitap to get the correct characters.

User Centric brought participants in for one-on-one time with a moderator for each of the tests. The test consisted of sending 12 standard text messages created for use in the study with each of the messages being between 104 and 106 characters long. Six of the messages contained instances of proper capitalization, while six had no capitalization and used some abbreviations.

Since none of the participants were iPhone owners, they were each given one minute to get familiar with the touch keypad. This study intended to show the decrease in productivity a new iPhone owner would see if they went from their current phone to the iPhone.

The study concluded that participants that normally used a phone with a QWERTY keypad took almost twice as long to enter the same text messages with the iPhone as they did with their normal phone. Participants who normally used a numeric multitap phone took nearly the same length of time to enter text messages on the iPhone.

“For QWERTY users, texting was fast and accurate. But when they switched to the iPhone, they were frustrated with the touch sensitive keyboard," said Jen Allen, Usability Specialist, User Centric.

Also noted in the study is the fact that many participants hit the wrong keys on the iPhone’s onscreen keyboard and the errors were typically corrected by using the backspace key to delete characters one at a time because of difficulty getting the cursor inserted correctly in the middle of text. Only seven study participants figured out how to use the iPhone’s corrective text feature on their own. Improvement with accuracy while using the iPhone after 30 minutes was noted, but the difference in speed between QWERTY phones and the iPhone persisted.

I have used the iPhone for about as long as the study participants while fiddling with a friends iPhone and using it at the Apple store. I fully agree with the inaccuracy of the keyboard. My fingers were too large and the keys were to close together for me to hit them accurately at any speed. I wished more than once for a stylus to hit the keys with.

"It's important to consider the changes a person has to make when they switch to the iPhone," said Gavin Lew, Managing Director at User Centric. "It should be easy for people to do common tasks, such as text messaging, using the iPhone's less traditional touch interface."

"everybody who is surprised that a flat greasy screen is slower than an actual keypad please raise your hand. nobody? that's what i thought."

Exactly... If you are an email or text addict, or just need to use those functions heavily for your job, you didn't buy an iPhone, it wasn't made for you, and it doesn't interface with MS Exchange, or Blackberry servers (which rules out 99% of companies out there). If you did buy it expecting a touch screen (even a really great touch screen) to be the same speed as a real tactile keyboard you are not too bright.

I think that the iPhone target market is the heavy email and text user.

I didn't mean to imply Apple wasn't going for that market, surely they are. I just meant that anyone that heavily relies on typing long or many messages (email or text) on their phone would be using a Qwerty keyboard model like Treo, Blackberry, Q or one of many others. A touch screen cannot compete.

iPhone was marketed towards the trendy dumbass phone user. You know, the kind that likes to pay a lot of money for a mediocre phone.

Don't tell me it's not mediocre. All the iPhone is, is an iPod with crappy phone capabilities, while at the same time, not implementing many features of other cellphones on the market. Hello!?! Camera anyone? Ya, we all know cellphone cameras, for the most part suck, but that doesn't mean we don't use them at all.
