conclusions the study showed that elevator buttons could lead to transmission of pathogenic bacteria. it is necessary to clean and disinfect elevator buttons daily, especially in departments with high contamination potential such as laboratories, particularly in biological laboratories and pilot plant rooms. methods the study was a across sectional research. samples were taken from elevator but...

Smartwatches are a promising new interactive platform, but their small size makes even basic actions cumbersome. Hence, there is a great need for approaches that expand the interactive envelope around smartwatches, allowing human input to escape the small physical confines of the device. We propose using tiny projectors integrated into the smartwatch to render icons on the user’s skin. These ic...

PURPOSE To develop an in vitro model of infectious crystalline keratopathy using human corneal buttons and to test the hypothesis that the compactness of the corneal stroma determines the pattern of microbial spread. METHODS Twenty human corneal buttons obtained after penetrating keratoplasty for keratoconus (KC) and eight human corneal buttons obtained from eye bank (EB) donor eyes were main...

An experiment was conducted to compare the recognition accuracy for static and animated buttons. Static and animated buttons were designed for 28 computer tasks. The tasks were categorized into low, medium, and high levels of complexity. Subjects identified the correct tasks of the animated buttons (78.6%) more often than for the static buttons (64.3%). The data were also analyzed for the numbe...

Graphical buttons are common to almost all interfaces but they are not without problems. One common difficulty is slipping off a button by mistake and not noticing. Sonically-enhanced buttons were designed to overcome this problem and were experimentally evaluated. Timing, error rates and workload measures were used. Error recovery was significantly faster and required fewer keystrokes with the...

Abstract We present a new interaction space for wearables by inlaying interactive elements, in the form of buttons, into outdoor clothing, specifically jackets and coats. Interactive buttons, or iButtons, allow users to perform specific tasks using inconspicuous gesture...

In order to conduct many desirable functions, service robots will need to actuate buttons and switches that are designed for humans. This paper presents the design of a robot named SwitchIt that is small, relatively inexpensive, easily mounted on a mobile robot, and actuates buttons reliably. Its operating characteristics were developed after conducting a systematic study of buttons and switche...
