The Mundane Computer: Non-Technical Design Challenges Facing Ubiquitous Computing and Ambient Intelligence
No full textInterdisciplinary collaboration, to include those who are not natural scientists, engineers and computer scientists, is inherent in the idea of ubiquitous computing, as formulated by Mark Weiser in the late 1980s and early 1990s. However, ubiquitous computing has remained largely a computer science and engineering concept, and its non-technical side remains relatively underdeveloped.
The aim of the article is, first, to clarify the kind of interdisciplinary collaboration envisaged by Weiser. Second, the difficulties of understanding the everyday and weaving ubiquitous technologies into the fabric of everyday life until they are indistinguishable from it, as conceived by Weiser, are explored. The contributions of Anne Galloway, Paul Dourish and Philip Agre to creating an understanding of everyday life relevant to the development of ubiquitous computing are discussed, focusing on the notions of performative practice, embodied interaction and contextualisation. Third, it is argued that with the shift to the notion of ambient intelligence, the larger scale socio-economic and socio-political dimensions of context become more explicit, in contrast to the focus on the smaller scale anthropological study of social (mainly workplace) practices inherent in the concept of ubiquitous computing. This can be seen in the adoption of the concept of ambient intelligence within the European Union and in the focus on rebalancing (personal) privacy protection and (state) security in the wake of 11 September 2001. Fourth, the importance of adopting a futures-oriented approach to discussing the issues arising from the notions of ubiquitous computing and ambient intelligence is stressed, while the difficulty of trying to achieve societal foresight is acknowledged
Mark Weiser and the Origins of Ubiquitous Computing
No full textIn today’s world, technology seems to touch every aspect of our lives. Our processes for so many things have become automated and digitalized. The use of networked computational devices by both end users and corporations has become, in a word, ubiquitous. In many ways, the era of rapid technological growth we find ourselves in currently can be traced back to the work of the pioneering computer scientist, Mark Weiser. It is widely accepted among technologists today that his original vision of “ubiquitous computing” played a large part in setting these events into motion in the first place. Yet the emergence of our technologies and the ways we use them has turned out to be something radically different from what Weiser had in mind.
As John Tinnell carefully explains in The Philosopher of Palo Alto, Weiser had in fact hoped for a future that would place computation all around us. Devices would perform specialized tasks regularly to enhance and improve our quality of life. The goal, however, according to Weiser’s view, was for these technologies to function always on the periphery of human perception. They were never meant to place any unreasonable demand on our attention. Operating in this manner, the devices designed to support human affairs could do so, and at the same time leave space for us to connect with the world and each other in essentially human ways
Hydraulophone design considerations : absement, displacement, and velocity-sensitive music keyboard in which each key is a water jet
No full textWe present a musical keyboard that is not only velocity-sensitive, but in fact responds to absement (presement), displacement (placement), velocity, acceleration, jerk, jounce, etc. (i.e. to all the derivatives, as well as the integral, of displacement). Moreover, unlike a piano keyboard in which the keys reach a point of maximal displacement, our keys are essentially infinite in length, and thus never reach an end to their key travel. Our infinite length keys are achieved by using water jet streams that continue to flow past the fingers of a person playing the instrument. The instrument takes the form of a pipe with a row of holes, in which water flows out of each hole, while a user is invited to play the instrument by interfering with the flow of water coming out of the holes. The instrument resembles a large flute, but, unlike a flute, there is no complicated fingering pattern. Instead, each hole (each water jet) corresponds to one note (as with a piano or pipe organ). Therefore, unlike a flute, chords can be played by blocking more than one water jet hole at the same time. Because each note corresponds to only one hole, different fingers of the musician can be inserted into, onto, around, or near several of the instrument’s many water jet holes, in a variety of different ways, resulting in an ability to independently control the way in which each note in a chord sounds. Thus the hydraulophone combines the intricate embouchure control of woodwind instruments with the polyphony of keyboard instruments. Various forms of our instrument include totally acoustic, totally electronic, as well as hybrid instruments that are acoustic but also include an interface to a multimedia computer to produce a mixture of sounds that are produced by the acoustic properties of water screeching through orific plates, as well as synthesized sounds
Das Ding namens Computer : eine kritische Neulektüre von Vilém Flusser und Mark Weiser
No full textComputer gelten als prägende Faktoren unserer Gesellschaft, ohne dass die ihnen zugesprochene Gestaltungsmacht systematisch hinterfragt würde. Gemeinhin werden sie als Rechenmaschine, Medium oder Notationssystem adressiert. Unklar bleibt, welcher Status Computern als Ding überhaupt zukommt. Mit ihrer kritischen Neulektüre von Vilém Flusser und Mark Weiser legt die Autorin zwei symptomatische Computerkonzepte im Diskurs des Digitalen frei. Sie zeigt, dass eine Reflexion der Gestaltungsmacht von Computern neben typischen Gebrauchsweisen gerade auch auf ihre potenzielle Widerständigkeit als Dinge abheben muss, um ihre Medialität angemessen erfassen zu können
