Purpose – Modelling users’ interactions online is envisaged to allow developers to increase the usability of online systems and will aid system developers in building better systems to meet users’ needs, hereby creating better system design processes. Design/methodology/approach – The normative task model that was developed in this paper was created through an expert review of 14 online grocery...

We tested if post-decisional emotions of regret, guilt, shame, anger, and disgust can account for individuals' choices in moral dilemmas depicting the choice of letting some people die (non-utilitarian option) or sacrificing one person to save them (utilitarian option). We collected participants' choices and post-decisional emotional ratings for each option using Footbridge-type dilemmas, in wh...

Methods and apparatuses for reducing the oscillatory motion of rotary crane payloads during operator-commanded or computer-controlled maneuvers. An Input-shaping filter receives input signals from multiple operator input devices and converts them into output signals readable by the crane controller to dampen the payload tangential and radial sway associated with rotation of the jib. The input s...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

There are available a number of mobile shopping aids and recommender systems, but none of which can be easily used for a weekly shop at a local supermarket. We present a minimalistic, mobile and fully functional lambent display that clips onto any shopping trolley, intended to nudge people when choosing what to buy. It provided salient information about the food-miles for various food items rep...

Three reported episodes of anaphylaxis, where 1:1000 adrenaline was not immediately obtainable, triggered us to assess its availability on all adult wards. We found adrenaline was unavailable on 50% of audited wards. A questionnaire for doctors and nurses revealed lack of knowledge on both the management of anaphylaxis and location of emergency drugs. Given that anaphylaxis is a treatable but p...
