| == General Touch Interaction Guidelines == The minimum area for touch activation, to address the general population, is a square 3/8” on each side (10 mm). When possible, use larger target areas. Important targets should be larger than others. There is no distinct preference for vertical or horizontal finger touch areas. All touch can be assumed to be a circle, though the actual input item may be shaped as needed to fit the space, or express a preconceived notion (e.g. button). {{attachment:GICintro-Sizec.png|The caption is up to you!}} |
== Getting Started == You now have a general sense of the types of input and output that will be discussed in this part. The following chapters will provide you specific information on theory, tactics, and illustrate examples of appropriate design patterns you can apply to specific situations in the mobile space. |
| Line 91: | Line 39: |
| === Targets === The visual target is not always the same as the touch area. However the touch area may never be smaller than the visual target. When practical (i.e. there is no adjacent interctive item) the touch area should be notably larger than the visual target. See the example to the right; the orange dotted line is the touch area. It is notably larger than the visual target, so a missed touch (as shown) still functions as expected. {{attachment:GICintro-Targetd.png|The caption is up to you!}} |
|
| Line 99: | Line 41: |
| === Touch area and the centroid of contact === The point activated by a touch (on capacitive touch devices) is the centroid of the touched area; that area where the user’s finger is flat against the screen. The centroid is the center of area whose coordinates are the average (arithmetic mean) of the co-ordinates of all the points of the shape. This may be sensed directly (the highest change in local capacitance for projected-capacitive screens) or calculated (center of the obscured area for beam-sensors). A larger area will typically be perceived to be touched by the user, due to parallax (advanced users may become aware of the centroid phenomenon, and expect this). {{attachment:GICintro-Centroidb.png|The caption is up to you!}} |
|
| Line 108: | Line 43: |
| === Bezels, edges and size cheats === Buttons on the edges of screens with flat bezels may take advantage of this to use smaller target sizes. The user may place their finger so that part of the touch is on the bezel (off the sensing area of the screen). This will effectively reduce the size of their finger, and allow smaller input areas. |

| This effective size reduction can only be about 60% of normal (so no smaller than 0.225 in or 6 mm) and only in the dimension with the edge condition. This is practically most useful to give high priority items a large target size without increasing the apparent or on-screen size of the target or touch area. | == Examples == If you want to add examples (and we occasionally do also) add them here. |

The varying ways people prefer to interact with their devices is highly dependent upon their natural tendencies, comfort levels, and the context of use. As designers and developers, we need to understand these influences and offer user interfaces that appeal to these needs.
User preferences may range from inputting data using physical keys, natural handwriting, or other gestural behaviors. Some users may prefer to receive information with an eyes-off screen approach relying on haptics or audible notifications.
This section, Input & Output, will discuss in detail the different mobile methods and controls users can interact with to access and receive information.
The types of input and output that will be discussed here are subdivided into the following chapters:
Chapter 9, Text and Character Input
Chapter 10, General Interactive Controls
Chapter 11, Input and Selection
Chapter 12, Audio and Vibration
Chapter 13, Screens, Lights and Sensors
Types of Input & Output
Text & Character Input
Whether the reason is sending an email, SMS, searching, or filling out forms, users require ways to input both text and characters. Such methods may be through keyboards and keypads, by hardware keys, touch screens and pen-based writing. Regardless of the method, they must each allow rapid input, while reducing input errors and providing methods of correction. This chapter will explain research based frameworks, tactical examples, and descriptive mobile patterns to use for text and character input.
General Interactive Controls
Functions on the device, and in the interface, are influenced by a series of controls. They may be keys arrayed around the periphery of the device, or be controlled by gestural behaviors. Users must be able to find, understand, and easily learn these control types. This chapter will explain research based frameworks, tactical examples, and descriptive mobile patterns to use for general interactive controls.
Input & Selection
Users require methods to enter and remove text and other character-based information without restriction. Many times users are filling out forms or selecting information from lists. At any time, they may also need to make quick, easy changes to remove contents from these fields or entire forms. This chapter will explain research based frameworks, tactical examples, and descriptive mobile patterns to use for input and selection.
Audio & Vibration
Our mobile devices are not always in plain sight. They may across the room, or placed deep in our pockets. When important notifications occur, users need to be alerted. Using audio and vibration as notifiers and forms of feedback can be very effective. This chapter will explain research based frameworks, tactical examples, and descriptive mobile patterns to use for audio and vibration.
Screens, Lights & Sensors
Mobile devices today are equipped with a range of technologies meant to improve our interactive experiences. These devices may be equipped with advanced display technology to improve viewability while offering better battery life, and incorporate location base services integrated within other applications. This chapter will explain research based frameworks, tactical examples, and descriptive mobile patterns to use for screens, lights, and sensors.
