Discussion of interface design caused by the iphone 4 day line problem

If you hold the lower left-hand corner of your phone, the IPhone 4G doesn't respond. http://www.aliyun.com/zixun/aggregation/10820.html, >steve Jobs, says there are two solutions to the problem: either "don't hold the phone like that" or wrap the phone with an iphone accessory. This is not a big problem, but it raises a debate about how to balance the relationship between technology and the user interface that uses it. Although no one has mentioned it, it's easy to think that having a higher resolution iPhone4 makes control difficult, and it's hard for someone with a big finger to operate precisely on the screen.

Hardware engineers are still adding more processing power to small devices, but the persistent obstacles are the same. This problem is particularly noticeable on mobile phones. Patrick Baudisch, from Hasso Plattner Cato, earlier this year at Microsoft, said:

There is now a real computing platform for the public, not a PC, not one Laptop per child, but a mobile phone, which has a high occupancy rate of several orders of magnitude. We need to do design work for this exciting and promising platform.

Interface problems not only interfere with the antenna of the larger fingers and skin conductance, some things can not even use, such as touch input, touch control is even lower than the accuracy of the mouse, in some environments even can not use the interface (for example, when the car is not able to use touch function).

Some of the problems and possible solutions are listed below: (Excerpts from the ACM Communications Conference of February this year)

Larger fingers. Baudisch is developing a technology called Nanotouch that allows the mobile device to display a translucent state and put the touch interface behind the device, which prevents the fingertip from blocking the interface. Baudisch is also working on a project called Ridgepad, which detects input areas and fingers in the area for more accurate input, and says the project "can increase the accuracy of the current touch technology to more than twice times." Limited surface area. Chris Harrison, a graduate of Carnegie Mellon University, is trying to use surface areas on mobile devices to improve input efficiency (he calls this technology scratch input). By using a small acoustic microphone in the device, the vibrations generated by the user tapping or tapping on the screen can be detected and used as an input signal. For example, you can tap your finger on your desktop to improve or lower the volume of your media player. Harrison also works with others to explore the use of deformable interfaces to create multi-touch buttons, scrollbars, and keyboards. Touch input. This is still the fastest way of data entry. Several commercial products now offer an external keyboard, or even a virtual keyboard projector, that can be projected onto any flat interface. Low precision of touch screen. Ilya Rosenberg and Ken Perlin of New York University have developed a force-sensitive impedance Technology (ISFR) that can sample overlapping areas on the touchscreen, with precision up to 25 times times the number of sensor arrays.

In the future, the interface may be completely detached from the device and put into our bodies. Visual displays include the human retina, the conductivity of the "speaker" to the human ear, and the tactile sensor in the finger.

Fundamentally, the "impedance mismatch" problem between the technical interface and the human user needs to be solved by the user rather than the technical expert. Like inventing a "new" language to circumvent the phone number/letter plate restrictions, users will find a solution. Technical experts need to take into account the impact of user creativity and culture, every day to experience the design of the constraints and inspiration of the spark, which will benefit them. The IPhone 4G has been in development for so many months, but no engineer has ever taken the bottom left-hand corner of the phone to see if the signal is broken, which is incredible. It is also inconceivable that Apple engineers and designers did not expect so many users to get used to the phone. The antenna design did not take into account the fact that it eventually led to this incredible thing or happened. Yi.
