To allow for producing high quality tactile graphics, the involvement of blind users in the production process can be a very vital approach. In this paper, we describe a col-laborative tactile graphic workstation. Thereby, a sighted user works with a conventional vector graphic production software while a blind user can edit the same graphic on a(More)
Differential cross sections of charged particles in inelastic pp collisions as a function of p T have been measured at √ s = 0.9, 2.76 and 7 TeV at the LHC. The p T spectra are compared to NLO-pQCD calculations. Though the differential cross section for an individual √ s cannot be described by NLO-pQCD, the relative increase of cross section with √ s is in(More)
The ALICE measurement of K(S)(0) and Λ production at midrapidity in Pb-Pb collisions at √(s(NN))=2.76 TeV is presented. The transverse momentum (p(T)) spectra are shown for several collision centrality intervals and in the p(T) range from 0.4 GeV/c (0.6 GeV/c for Λ) to 12 GeV/c. The p(T) dependence of the Λ/K(S)(0) ratios exhibits maxima in the vicinity of(More)
The Tangram Workstation is a collaborative system for creating tactile graphics. A transcriber composing a tactile graphic from a visual source is supported by a non-visual reviewer on a two-dimensional tactile pin-matrix device on which he can observe and adapt the work of his sighted team member. We present the results of an evaluation with eight teams,(More)
