Electrophysiological evaluation of symmetrical analogues of the known maxi-K opener NS-004 (1) led to the discovery of bisphenols 2a, 3a and 4a as openers of cloned maxi-K channels expressed in oocytes.
This paper addresses knowledge-based authentication systems in self-service technology, presenting the design and evaluation of the Visual Identification Protocol (VIP). The basic idea behind it is to use pictures instead of numbers as a means for user authentication. Three different authentication systems based on images and visual memory were designed and… (More)
This paper presents a preliminary evaluation of Alice, a chatterbot designed in order to elicit anthropomorphic attributions and emotional reactions from those who chat to 'her'. The analysis is based on both transcripts of the interaction and user comments collected in a focus group. Results suggest that the introduction of explicit anthropomorphism in… (More)
The preparation and binding affinity of a series of tetrahydroisoquinoline carboxylic acids at the N-methyl-D-aspartate (NMDA) subtype of the glutamate receptor is described, together with a molecular modeling analysis of NMDA agonists and antagonists. Using published NMDA ligands, the active analogue mapping approach was employed in the generation of an… (More)
Our research investigated whether the presence of an interface agent – or virtual assistant (VA) – in a self-service checkout context has behavioural effects on the transaction process during particular tasks. While many participants claimed to have not noticed a VA within the self-service interface, behaviour was still affected, i.e. fewer people made… (More)
This panel discusses biometric technologies from different perspectives in HCI in order to arrive at a coherent response that the community can give in this area. The challenges of doing this will also be of interest in terms of HCI's general influence on topical issues.
