Spin box The combination of one (and usually more) controls plus the system response is called a widget. Widgets are the building blocks of any application or device. An MP3 player, for instance, is made of widgets: one for controlling volume, one for controlling the playing of music files, one for organizing files, one for exporting files, and so on. In each case, the user uses controls to perform an action, and the system responds. All applications and devices are made up of widgets. 6.7. Non-traditional Inputs controls We are arriving at a time when keyboards, mice, and styluses aren't the only-and possibly not even the primary-way we interact with the digital world. With the dawn of ubiquitous computing, interactive environments, and sensor-enabled devices, people will engage with many different sorts of objects that have microprocessors and sensors built into them, from rooms to appliances to bicycles. The controls for these faceless interfaces are the human body: our voices, our movements, and simply our presence.(9) 6.7.1. Voice: Widespread implementation of voice-controlled systems has been on the horizon for at least a decade now. For now, voice-controlled interfaces are most prevalent (naturally) on phone systems and mobile phones. For example, people call their banks and perform transactions or dial their mobile phones with just their voices. Voice commands typically control limited functionality, and the device typically has to be ready to receive voice commands, either because it only functions via voice commands (as with automated phone systems and some voice-controlled devicessee or because it has been prepared to receive voice commands, as with mobile phones that allow voice-dialing. 6.7.2. Gestures in space: To most computers and devices, people consist of two things: hands and eyes. The rest of the human body is ignored. But as our devices gain more awareness of the movement of the human body through sensors such as cameras, the better able they will be to respond to the complete human body, including gestures. Devices like the Wii and
