We describe the design of modules in the current version of the TINA stereo based 3D vision system responsible for the recovery of geometric descriptions and their subsequent integration into partial wire frame models. The approach differs considerably from that described in an earlier version of the TINA system [2, 3]. Our strategy for the construction of partial wire frame descriptions is bro...

How do things come to embody meaning? In much anthropological and sociological writings, things have mainly been considered in two ways: either as commodities or as gifts. Correspondingly, people’s relationships to things and to other people seem to fall in two broad categories, often regarded as mutually exclusive: either as impersonal, economic or market relationships with strangers, or as pe...

Today, in 1996, my fascination with these problems is undiminished. But I've developed a certain angst over the intervening thirtysomething years—a constant, nagging feeling that our field spends a lot of time spinning its wheels without really making all that much progress. This problem shows up in obvious ways—for instance, in the regularity with which findings seem not to replicate. It also ...

-This paper develops a novel spectrum enhancement method to simplify the spectrum representation. It uses a forward synchronous transform to convert three phase current signals into the two current signals in the synchronous reference frame. The spectrum obtained by applying Fast Fourier Transform (FFT) to one of the transformed current signals is then maximized by varying the initial phase in ...

Several workshops use toolkits to engage children in the design of smart things, that is, everyday things like toys enhanced with computing devices and capabilities. In general, focus on one stage or another, e.g., ideation programming. Few are created guide through an entire process. This paper presents a toolkit for smart-thing children. It revolves around SNaP, card-based board game The serv...
