Designing Bespoke VR Input Devices for People With Physical Disability
No full textVirtual Reality (VR) promises to immerse users in virtual environments, but access barriers for people with mobility disability that are related to the body-centricity of the technology remain. While existing research has begun to develop software solutions, there is a lack of accessible VR input devices with dedicated interaction paradigms for people with mobility disability. In this work, we present two complementary Research through Design (RtD) case studies creating bespoke VR solutions: We designed unobtrusive VR gloves for a manual wheelchair user to allow complex interactions while simultaneously operating the wheelchair, as well as a VR gamepad with a personalized button layout as an alternative to conventional handheld input devices for a powered wheelchair user. Our results show the potential of employing RtD for experience-focused VR accessibility research. We provide recommendations for designing accessible VR input devices and interaction paradigms, and reflect on the challenge of achieving scalable, bespoke V
Intertwined orders in a quantum-entangled metal
No full textEntanglement underpins quantum computing and information processing, yet its quantitative characterization in correlated materials remains an outstanding challenge. Here we report a highly entangled electronic phase near a quantum metal–insulator transition identified by resonant inelastic X-ray scattering interferometry. Entanglement extending across atomic sites generates distinct interference patterns that are accurately captured by theoretical modelling, enabling quantitative reconstruction of the entanglement spectrum and microscopic resolution of the underlying quantum states. In the pyrochlore iridate NdIrO, pronounced quantum fluctuations of spin, orbital and charge persist within the long-range ‘all-in-all-out’ antiferromagnetic order. The observed entanglement signatures indicate the coexistence of multiple symmetry-breaking orders, supported by complementary Raman spectroscopy investigations. A two-magnon bound state appears below the lowest single-magnon excitation energy, which together with split phonon modes indicates a cubic symmetry breaking of magnetic origin coexisting with the all-in-all-out order. These findings establish a quantitative framework linking quantum entanglement to emergent unconventional orders

No full textRenewable energy powered membrane technology: Design of a photovoltaic hybrid ultra- and nanofiltration membrane mobile laboratory
No full textThe design, construction, and performance testing of a mobile, photovoltaic-powered, hybrid filtration system, equipped with both micro-filters and nanofiltration (NF) membranes is described. This ‘mobile lab’ enables autonomous research with a wide range of water sources – from desalination of brackish water to treatment of contaminated low salinity groundwater. Firstly, the system performance was investigated as a function of five different NF membranes and feedwater salinity (1–20 g/L). The importance of choosing the correct set-point in operating pressure for experiments is discussed in order to map out the safe operating window (SOW) of different system configurations (membranes, feed waters). Secondly, a case study was conducted using real water contaminated with naturally-occurring uranium, where the system was able to treat the water to achieve the World Health Organization guideline values at a specific energy consumption of 1 kWh/m3. The benefit of using supercapacitor energy storage for buffering solar power fluctuations was explored. Despite testing a wide salinity range, the system was observed to achieve drinking water standards at salinities as low as 5 g/L with the NF90 membrane, clearly defining a SOW for treating primarily brackish water. Three membranes exhibited limited salt retention and only achieved satisfactory performance at the lowest NaCl salinity (1 g/L), Overall, this work helps pave the way for the design of photovoltaic-powered membrane filtration systems for both mobile (disaster relief) and stationary (drinking water provision in remote areas) scenarios supported by research that enables field work and excellent research training opportunities to contribute to solving global challenges
