- Spatial Augmented Reality has shown promising results to support the industrial design process, this paper explores improvements by incorporating tangible buttons to allow dynamically positioned controls with a wearable glove sensor system for simulating prototype design functionality. We present a system to support the low cost development of an active user interface that is not restricted to the two-dimensional surface of a traditional computer display.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Reliability of intraoral quantitative sensory testing (QST) in patients with atypical odontalgia and healthy controls – a multicenter study The reliability of a comprehensive intraoral quantitative sensory testing (QST) protocol has not been examined systematically in patients with chronic orofacial pain. Also, the reliability of QST z-scores has not been reported. Aim of Investigation: The aim of the present multi-center study was to examine test-retest and inter-examiner reliability of intraoral QST measures in terms of absolute values and z-scores as well as within-session coefficients of variation (CV) values in patients with atypical odontalgia (AO) and healthy pain-free controls. Methods: Fourty-five AO patients and 68 healthy controls were subjected to bilateral intraoral gingival QST and unilateral extraoral QST (thenar) on three occasions (twice on one day by two different examiners and once approximately one week later by one of the examiners). Interclass correlation coefficients and kappa values for inter-examiner and test-retest reliability were computed. Results: Most of the standardized intraoral QST measures (absolute values and z-scores) showed fair to excellent inter-examiner (9-12 of 13 measures) and test-retest (7-11 of 13 measures) reliability. Furthermore, no robust differences in reliability measures or within-session variability (CV) were detected between AO patients and the healthy reference group. Conclusions: These reliability results in chronic orofacial pain patients support earlier suggestions based on data from healthy subjects that intraoral QST (absolute values as well as z-scores) is sufficiently reliable for use as a part of a comprehensive evaluation of patients with somatosensory disturbances or neuropathic pain in the trigeminal region.

Konferensbidrag (refereegranskat)abstract
- An ultra-relativistic electron beam passing through a thick, high-Z solid target triggers an electromagnetic cascade, whereby a large number of high energy photons and electron-positron pairs are produced. By exploiting this physical process, we present here the first experimental evidence of the generation of ultra-short, highly collimated and ultra-relativistic positron beams following the interaction of a laser-wakefield accelerated electron beam with high-Z solid targets. Clear evidence has also been obtained of the generation of GeV electron-positron jets with variable composition depending on the solid target material and thickness. The percentage of positrons in the overall leptonic beam has been observed to vary from a few per cent up to almost fifty per cent, implying a quasi-neutral electron-positron beam. We anticipate that these beams will be of direct relevance to the laboratory study of astrophysical leptonic jets and their interaction with the interstellar medium
