The physicality of digital-physical devices is an essential part of our interaction and understanding of information appliances. This paper draws on the findings of an empirical study investigating the effect of physical fidelity on a series of user trials. Three prototypes of a single design intent were built, the standard of their construction dictated by the time imposed on the designer. In ...
The purpose of this study was to compare the effects of a differently designed functional appliance (the R-appliance) with a twin-block (TB)-treated group. Thirty patients (18 girls and 12 boys) with a mean age of 10.5±0.7 years were treated with the R-appliance for 16.2±0.3 months and 25 (11 boys and 14 girls) with a mean age of 11.2±1.3 years with a TB for 16.1±1.4 months (control). All had a...
The aim of this study was to evaluate the change in mandibular position during a two-phase orthodontic treatment of skeletal Class II malocclusion. Thirty consecutively treated Chinese male adolescents who had undergone two-phase treatment with Herbst appliance and fixed appliance and fulfilled the specific selection criteria were sampled. Cephalograms taken at T0 (before treatment), T1 (at the...
