Despite the wide availability of body-sensing technologies, the design of control gestures that feel natural and that can be intuitively "guessed" by the users is still an embodied interaction challenge. This is especially true for systems that require a <i>set</i> of complementary control gestures. Part of the problem lies in the separation between the(More)
Museums are increasingly embracing technologies that provide highly-individualized and highly-interactive experiences to visitors. With embodied interaction experiences, increased localization accuracy supports greater nuance in interaction design, but there is usually a tradeoff between fast, accurate tracking and the ability to preserve the identity of(More)
As data rather than physical artifacts become more commonly the product of modern scientific endeavor, we must attend to humandata interactions as people reason about and with representations of data increasingly being presented in museum settings. Complex data sets can be impenetrable for novices, so the exhibit presented here was designed to give visitors(More)
Many factors are known to mediate museum visitors' learning during their interactions with exhibits, including designed elements of the exhibit itself, the other visitors present in the space, and visitors' own backgrounds and prior knowledge. Research indicates that learners' use of a first-person <i>Actor</i> perspective may confer agency to the learner(More)
The "Uncanny Valley" theory explains the counter-intuitive phenomenon where people may get suddenly uncomfortable with an artificial entity when it becomes very similar to humans. We propose the existence of an "uncanny valley" for embodied interaction, when a user's body motions in the physical space (the locus of interaction) are incompletely mapped into(More)
RFID is usually used for <i>identification</i> but with some post-processing it can also be used for <i>localization</i>. These properties expand the typical range of possible interactions with digital displays in museums. Our goal is to encourage the collaborative investigation of a rich information space presented on an Ambient Display in a museum(More)
The adaptation and use of advanced technologies is an effective and encouraging way to efficiently and reliably characterise crops and plants. Additionally advances in these technologies will improve the information available for agronomists, breeders and plant physiologists in order to develop best management practices in the process and commercialization(More)
Maintaining appropriate exposure times is challenging in applications that involve continuous capturing and processing of images in an environment of dynamically changing light. This problem is typically solved by post processing the captured images and adapting the exposure time for the next image based on some brightness metric derived from a previous(More)
α-Conotoxin MII (α-CTxMII) is a 16-residue peptide with the sequence GCCSNPVCHLEHSNLC, containing Cys2-Cys8 and Cys3-Cys16 disulfide bonds. This peptide, isolated from the venom of the marine cone snail Conus magus, is a potent and selective antagonist of neuronal nicotinic acetylcholine receptors (nAChRs). To evaluate the impact of channel-ligand(More)
