When typing on a computer, keying in a phone number on a telephone, or a PI Number on an ATM or POS, isn't tactile feedback just as relevant as it is for other applications? Absolutely yes. That's why you can't (reliably) use your touchscreen smartphone if you can't look at it. I used to write SMSs doing something else because muscle memory did all the ...

Advantages A touch screen has the advantage of greater context sensitivity. The sizes, shapes, colors, and labels of controls can change during operation to reflect what is needed for a particular step of a process. Non-touch devices often simulate this by placing a control next to the bottom or side of the screen and displaying a label next to that ...

One less device We use touch screens because it removes the device that acts as a proxy for our hands. Humans act on the physical world haptically—through touch and pressure. A mouse, or other pointing device, lets the user move a pointer that represents a finger. Touch removes the need for the proxy device. It also enables multi-touch in a way that ...

I have a critical view on touchscreen usage, but their huge advantage is the flexibility of dynamic interaction and representations. It is not related strictly with money -- you simply can't create some complex transitions with physical controls. Another reason is direct manipulation. It is still not perfect because of lack of tactile feedback and some ...

Try using a modified version of the first one, perhaps like so: What this essentially is is the first one, but with a box above to give an elegant preview of what you are currently pointing at. It will be above the user's fingers, and therefore out of their way. The reason I chose the first slider is because it has a bar, which is definitely the best way ...

ACM Digital Library (dl.acm.org) is really helpful when doing focused literature review. For more general research you can access Google Scholar search engine. I also recommend a great tool called Mendeley, that keeps track of your research and uploads all your material to the cloud (also generates the citations...) There are a number of papers on ...

A little about touchscreen POSes in a service industry environment. They are actually enormously advantageous over tactile buttons for a few reasons. Button assignments change frequentlyIn the older registers with tactile buttons, the function of the button would have to be reprogrammed when an item changed. Not only would the price, item categories, ...

Scrolling pattern and navigation largely depends on the information architecture and content strategy of your website. The page scroll UI pattern has been largely used to showcase features of a product and I think it has been misused in this way. In most cases, the features are not peers but are related/dependent on each other. It seems page section ...

Apple has published couple of guidelines. With regards to 3D Touch, they seem to be taking hands-off approach on the discoverability because its usage patterns can be quite varied. https://developer.apple.com/library/prerelease/ios/documentation/UserExperience/Conceptual/Adopting3DTouchOniPhone/ Indication of peek availability With a light press, ...

Touchscreens are great for when you can take your eyes off the road. Which, while driving, is a vanishingly small part of the time. Most of the commonly used functions in a car remain with knobs (NOT sliders which are horrible in a bouncing vehicle) buttons and stalks because you can reach in the right direction, grasp the proper control by feel, and actuate ...

I don't think you can rely on it and should always check if the hardware is present. My best estimate would be that this is, in most cases, true, albeit the devices that are "smart" and powerful enough to run said application. That being said, have you considered the usability part of such an idea, like, how can they discover this gesture? Will they have to ...

It is never really safe to assume anything along these lines. No not all touch devices in the past 5 years will have gyroscopic technology (the feature that registers tilt). I have had quite a few lower end cell phones with touch input but no gyroscope (or other related features like accelerometer). Even if the device did have a gyroscope maybe it will be ...

What are the advantages to using a touch screen for a user interface in a computing device or a thermostat, compared to an input device that provides tactile feedback? Since you are asking for advantages I will try to just list the advantages here I see: State can be saved and restored quite simple. A physical slider would require to be motor driven ...

Touchscreens offer almost infinite possibilities for variable user interfaces, but tactile buttons offer accuracy, speed, motor memory and safer operation in a moving vehicle. There seems to be a an almost stalemate between the desire to offer a flexible UI and the need for physical buttons in a moving vehicle. But there may be a solution... Why not offer ...

A map pin denotes a location, it doesn't give you info about what that location is in order for the user to make the decision that "Yes, I'm interested in this location". So something like this may make sense download bmml source – Wireframes created with Balsamiq Mockups When user clicks/taps on the pin, display a popover with details about ...

Is there a reason why the user needs to see the Saturday menu on Tuesday? If not, present options only for that day (default always to today on opening) and if the user needs to select for another day she can choose the day and then see the options for that day. This will also allow more room for the options because the type would have to be pretty small ...

long-press - for first item selection touch - for subsequent selections According to Google https://www.google.com/design/spec/patterns/selection.html# The global gesture to select data is a long-press, a touch or mousedown that’s held in the same position for a moment. A two-finger touch may also trigger selection on touch devices. Item ...

I believe you are referring to arabic speaking countries in the middle eastern region. While most commonly left to right is the swipe direction, It would need to be in reverse in this case, i.e. swiping right to left, just as the way they read from right to left as well as books also start at the opposite end compared to western books.

What kind of risks or concerns should I know about? When I completed my first kiosk project I neglected to think about the uptime requirements and the boot process. Specifically: what hours will the kiosk run? who will start/stop the kiosk? what happens if the power goes out? It is critical to pick a platform that you can write an automated boot ...

As said in Wikipedia, TLM is an addition to GOMS family, a mutation of a sorts of KLM (keystroke level model). They both use a method of splicing user tasks into ever smaller pieces of action, all the way down to, as name suggests, keystroke level. In KLM these actions has durations that have been obtained empirically. When you know the sequence of actions ...

Ouch! No matter why this happened you have to deal with your frustrated users. It doesn’t matter if you didn’t read the terms properly or if Apple change something along the way – you have a serious usability issue. What you can do is to explain that this happened. It may ease the pressure some of your users feel, and the one topic to grasp that users ...

Touch screens are not in and of themselves good or bad at any given application. As someone who designs, builds and tests kiosk and kiosk software for a living it might be surprising to hear that I think physical interfaces are better (currently) at all kinds of tasks, especially in the car. One of the problems is that touch screens are relatively new tech ...

There is one clear advantage to use touch screens. Its not really a UX question though. Touchscreens are cheaper for the manufacturer to design for. Designing the buttons and fixing the interaction is a costly process requiring mechanical engineering and sourcing. A touch screen is essentially easy to place in. It is also easy to developers of the ...

Author of the original TLM paper here. I just now saw this question and wanted to respond. The answer from @locationunknown above is pretty spot on, but I did want to comment on FLM and the status of TLM. FLM and TLM do appear fairly similar (I haven't read the FLM paper, I'll try to get access and update this answer once I've had a chance to look at it), ...

Either tablet or desktop, this combination has been problematic forever. It's used a lot in video editing software. You have to zoom the timeline in, which in turn, enlarges the task. This enables you to grab the left or right edge and extend. I like how Apple solves this, although it's a slightly different use case. When you select text, you'll get the two ...

The normal practice is to let the keyboard hide the bottom content. Reasons: Users are used to this convention , they are familiar with touching on the screen to hide the keyboard and touching the keyboard icon ( or any text field , if they are in the middle of some data entry ). The user is used to not seeing the bottom part and bringing it up using the ...

There's something known as a Selection Mode in Mobile devices that can be triggered by long pressing one row/ item/ element. This mode brings different actions on the screen as well as allowing to select multiple items or single row/ item/ element with just one tap as long as you are in that mode. This avoids you to have visible check boxes on either ...

Should we be considering taking interface cues from the physical world instead of older generations of computers? I think this question is setting up a false premise that it's one or the other. I'd argue it's likely neither. The best practice these day is to consider 'mobile first' to accommodate the very real fact that more and more people are using ...
