Mobile crossover in TxtPert

I posted a few months ago about a PC keyboard that uses a Bell keypad and predictive text. Now Carlo Longino at MobHappy spotted this in USA Today:

Shredding on a Keyboard

ishot-2 JamLegend, a Guitar Hero / Rock Band service for the PC, piqued my interest just because of the illustration that showed how you can play along with your keyboard by holding it guitar-style. It spurred the thought: how can we hold ordinary objects in different ways so that they become different things entirely?

Text input fields deconstructed

Morten Hjerde has taken a long hard look at text input field design.

“Edit-in-place is preferable in most cases. A person can see the context, and the visuals is consistent. Full screen editing is preferable when the user is likely to enter a large amount of text. Predictive text (T9, etc) may only be available in full screen edit.”

Predictive text input for PCs

What’s new is old. Cre8txt has made a keyboard for PCs that uses a Bell Keypad-based predictive text input system that is “designed to capture the texting skills that so many young people have and allow those skills to be used to input words onto a computer”.

Design challenges for mobile UI

“The single most important concept to master when designing mobile device interfaces is “context”. The context in which an application is used and the context of how information is input are both key issues; each must be understood before a well crafted design may be implemented. When these two notions of context are explored, it becomes clear that designing for a mobile device can lead to a solution that is worlds different than its desktop equivalent.”

One handed or two?

iPhone input-related articles keep rolling on in – this one from CNET is an interesting discussion on one-handed vs two-handed operation.

“The smart phones that most people are familiar with—the Nokias, BlackBerrys and Treos—only require one hand for basic operation. Obviously, typing on the QWERTY keyboards used by most of those devices is a two-handed operation, but navigating through the menu, looking up a contact, and using countless other functions only requires a single hand. “Everyone is still trying to make a one-handed product,” Rolston said. “It’s the easiest way to distinguish a truly portable device from a workstation. Handhelds are about doing something else (while using the handheld), they fit within the context of people’s active lives.””

The iPhone’s lack of haptic feedback

“If there is a billion-dollar gamble underlying Apple’s iPhone, it lies in what this smart cellphone does not have: a mechanical keyboard. As the clearest expression yet of the Apple chief executive’s spartan design aesthetic, the iPhone sports only one mechanical button, to return a user to the home screen. It echoes Steven P. Jobs’s decree two decades ago that a computer mouse should have a single button. (Most computer mice these days have two.) His argument was that one button ensured that it would be impossible to push the wrong button.”

Puttings small screens next to keys

I’m not sure whether to be excited or terrified by NeoKeys. They’ve removed the labels from the keypad and placed several rows of LCDs above an enlarged keyset. The benefit is that the key behaviors can adapt to context through very specific labeling (fantastic!). The problem is that the keypad layout is fixed for every interaction, and is severely lacking in visual cues to help interpret the context and controls. Looking at some of the product shots and demos makes me feel like I’m looking at an ATM on steroids; there’s just so much to process and so little helping me focus.

The only benefit NeoKeys offers above a dual screen configuration is the haptic response of the keys and the ability to easier target the buttons (but haptic technology is not far away from becoming a reality on touchscreen consumer goods). They’ve done a good job showcasing the invention on the site that boldly claims the system is “a new way to do everything”.

Text input, upside down

A design for texting with the device orientation inverted. This is just a patent application, and not a real product. It’s an interesting idea, though, because it doesn’t ask people to learn new input systems but rather just change the orientation of the device.

“Typing text messages in this manner is awkward, as the mobile is merely held pinched between the middle finger and the palm, while most of the handset extends unstably beyond the user’s palm. Furthermore, the thumb’s range of movement is restricted by the lower orientation of the keypad.”

Text input methods, again

Little Springs Design has put together a nice summary of different text input methods for mobile devices, including different hardware and software solutions.

“We have categorized various text input mechanisms for mobile devices based on usage scenario. We count not just the number of hands needed to press keys on the device, but also the number of hands and surfaces needed to control the device. Hence, a full-sized QWERTY keyboard is a two-handed device that requires a surface. We’ve included voice (speech recognition) as a separate category here.”

Fitt’s Law for mobile devices

Little Springs Design have published a couple of short pieces on applying Fitt’s Law to mobile devices.

“Fitt’s Law (circa 1954) states that the time to acquire a target is a function of the distance to the target and the size of the target. The further the target is away from the user’s current position, the longer it takes to move to the target. The smaller the target, the more the user has to use fine muscle control and hence take more time to move.”

Mobile game design process review

A post-mortem of the creation of the mobile game “Tower Bloxx”.

“As we discussed earlier, the original idea came from a mock-up image which was later turned into a prototype, which led to our core mechanics. After production started, we also needed something to fill the long-term gameplay demand, so we had several ideas of how the rules of the city mode could work, and we prototyped those using both pen-and-paper and Excel. In this way, we could test and tweak our ideas without the need for programming time, which helped us getting the game done faster.”

The next generation mobile UI

“Many of these issues are about solving the complexity problem: enabling lots of different features for lots of different users in lots of different cultures. Will tomorrows intuitive interfaces use RFID to allow us to interact with our environment in a more tangible manner, in a way similar to how people in cities like London or Helsinki already use touch-cards to pay for public transport? Probably. Will they have speech-to-text and text-to-speech functionality to enable varied, fast, and context-sensitive input and output? Probably. Will they use motion sensors to allow us to input data in new ways, using movement rather than key presses? Possibly. Will they have different modes, allowing users to prioritise different things depending on context (work / entertainment / personal / social / static / mobile)? Maybe. Will they require a clear understanding of user needs and behaviour in order to be successful? Definitely.”
