There are so many devices that are based on touch technology. There is the iphone/ipod touch, blackberry's and even some computers have this technology. However it is still preferable to use standard physical objects to control media and use a phone or computer. There is now a way to combine the two technolgies. It seems that researchers at RWTH Aachen University in Germany in conjunction with UC San Diego have created the SLAP (Sillicone Illuminated Active Peripherals). These widgets are plastic and sillicone objects that are used in conjunction with a multi-touch table that lets users to control interface values through physical push buttons, sliders, knobs, keypads and keyboards. The way this all works is very interesting, when a widget is placed atop the surface, a camera can read markers that are underneath it in order to identify and locate the widget. The user can manipulate movable parts such as a moving a slider knob or spinning a dial. This is best used for tasks that require precision, like locating a specific frame in a video. This is because it is better handled through physical input devices than through virtual ones. As someone who will be working on video editing as a career this is very helpful. As convenient as it can be to use touch technology on some devices like an ipod, some things dont require it and it is nice to know that there are other technological options out there.
