The temporal dimension of acceptance is under-researched in technology acceptance research. Yet, people’s perceptions on technology use may change over time when gaining user experiences. Our 6-month home study deploying an interactive robot provides insight into the long-term use of use interactive technology in a domestic environment. We present a phased framework for the acceptance of interactive technology in domestic environments. Based on 97 interviews obtained from 21 participants living in different household types, the results provide an initial validation of our phased framework for long-term acceptance showing that acceptance phases are linked to certain user experiences which evolve over time when people gain experience with the technology. Involving end users in the early stages of development helps researchers understand the cultural and social contexts of acceptance and enables developers to apply this gained knowledge into their future designs.
This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity is analysed. The annual energy yield of a micro wind turbine is estimated and compared using data from a micro-wind turbine wind tunnel experiment and field data. Electrical energy costs are discussed as well as structural integration cost reduction and the potential energy yield could decrease costs. It was found that instantaneous wind direction towards the barrier and the height of observation play an influential role for the results. Wind speed increases in perpendicular flows while decreases in parallel flow, by +35% down to −20% from the reference. The azimuth of the noise barrier expressed in wind field rotation angles was found to be influential resulted in 50%–130% changes with respect to annual energy yield. A micro wind turbine (0.375 kW) would produce between 100 and 600 kWh annually. Finally, cost analysis with cost reductions due to integration and the energy yield changes due to the barrier, show a LCOE reduction at 60%–90% of the reference value. https://doi.org/10.1016/j.jweia.2020.104206
Door klimaatverandering worden in stedelijke gebieden steeds vaker normen en/of acceptatiegrenzen voor neerslag, hitte en droogte overschreden. Gemeenten en waterschappen hebben de taak om te zorgen voor een klimaatbestendige inrichting. Daarbij is de samenwerking met bewoners voor hen essentieel. Om de stap naar uitvoering te kunnen maken hebben professionals van gemeenten en waterschappen behoefte aan inzicht in effecten op microniveau (straten/gebouwen), lokale ervaringen en beleving door burgers, en hoe burgers betrokken kunnen worden bij maatregelen. Eén van de manieren om samen te werken met burgers is door hen te betrekken bij het in kaart brengen van risico's en maatregelen: burgerwetenschap. Burgerwetenschap en in het bijzonder participatieve monitoring is een vakgebied dat sterk in opkomst is. Het is een methode waarbij onderzoekers, professionals en maatschappelijke actoren zoals vrijwilligers en bewoners samenwerken om in lokale projecten data te verzamelen en te duiden.
