Wow!: objects

Nowadays computers have advanced beyond the desktop into many parts of everyday life and objects. To achieve this we have to make the computer invisible, and making a computer invisible is not a matter of size of the hardware, it’s all about how the human perceives the computer. To make this possible, the interaction with the computer has to be done in an alternative way, such that the user doesn’t notice the usual computer interfaces (mouse and keyboard) when using it. Therefore this thesis focuses on physical objects that are interactive to achieve various purposes like persuasive objects for stress relief, persuasive objects to help the process of teaching, persuasive objects for fun, persuasive objects to display internet information and persuasive objects to make people feel more in community (exchange virtual emotions), persuasive objects are going to be created and evaluated to see if they have the power to simplify and turn our lives better. The persuasive objects developed employ technology like sensors, actuators, microcontrollers, and computer/web services’ communication. This Master thesis starts by presenting a comprehensive introduction of what are persuasive objects and some general information about several areas that are related to our persuasive objects like stress relief, work experience, multimedia education and other major aspects. It continues by describing related work done in this area. Then we have a detailed view of each persuasive object and finally this thesis finishes with a general conclusion and notion of future work.

Motivating the use of public transit through a mobile glanceable display

With increasing concerns about the impact of global warming on human life, policy makers around the world and researchers have sought for technological solutions that have the potential to attenuate this process. This thesis describes the design and evaluation of an information appliance that aims to increase the use of public transportation. We developed a mobile glanceable display that, being aware of the user’s transportation routines, provides awareness cues about bus arrival time, grounded upon the vision of Ambient Intelligence. We present the design process we followed, from ideation to building a prototype and conducting a field study, and conclude with a set of guidelines for the design of relevant personal information systems. More specifically we seek to test the following hypotheses: 1) That the tangible prototype that provides ambient cues will be used more frequently than a similar purpose mobile app, 2) That the tangible prototype will reduce the waiting time at the bus stop, 3) That the tangible prototype will result to reduced anxiety on passengers, 4) That the tangible prototype will result to an increase in the perceived reliability of the transit service, 5) That the tangible prototype will enhance users’ efficiency in reading the bus schedules and 6) That the tangible prototype will make individuals more likely to use public transit. In a field study, we compare the tangible prototype against the mobile app and a control condition where participants were given no external support in obtaining bus arrival information, other than their existing routines. Using qualitative and quantitative data, we test the aforementioned hypotheses and explore users’ reactions to the prototype we developed.
