In this paper, we describe an industrial experience with the creation of a new product for collaboratively navigating and reviewing 3D engineering models, applied to the oil industry. Together with professional oil industry engineers from a large oil company, a team of HCI researchers performed task analysis and storyboards, designed, implemented and(More)
T-cell malignancies in Brazil have a high seroprevalence rate of HTLV-I antibodies. We have analyzed the disease features in 188 Brazilian patients with a T-cell disorder. These included 40 with T-lymphoblastic leukaemia or lymphoma (T-ALL/T-LbLy) and 148 with mature T-cell diseases: 5 T-prolymphocytic leukaemia, 53 adult T-cell leukaemia/lymphoma (ATLL),(More)
Combination chemotherapy has had a low impact on survival of blast crises in chronic myelogeneous leukaemia (CML) which may be due to drug resistance. This work attempted to correlate the clinical response and some experimental evidence for the MDR phenotype. Blast cells were positive for P-glycoprotein using APAAP assay. In vitro tests showed that(More)
Alternative therapy for refractory leukemic patients is being increasingly adopted. Circumvention of multidrug resistance represents a strategy that has been taken into account when conventional chemotherapy failed. In this work a group of 15 refractory, heavily pretreated, patients was enrolled in a circumvention protocol including etoposide (ETO) and(More)
Human work interaction design is an emerging discipline that aims to encourage empirical studies and conceptualizations of the interaction among humans, their variegated social contexts and the technology they use both within and across these contexts. In this paper the authors present a virtual reality system for visualization, navigation and reviewing of(More)
The usage of multimodal user interfaces has revolutionized many different activities. However, most of the interactive technologies deployed in real world engineering contexts are still difficult to use, especially when engineering teams need to collaboratively visualize and review large-scale 3D CAD (Computer-Aided Design) models. This is the case of the(More)
This paper tries to identify increases in user frustration when using Eye-Tracking devices as compared to common interfacing devices like a standard mouse. For this, we used an electroencephalograph (EEG) to measure frustration levels while users navigated within a maze using each of the referred devices. Results from the analysis performed on the EEG data(More)
