The increasing use of touchscreen interfaces in vehicles poses challenges to designers in terms of optimizing safety, usability and affective response. It is thought that the application of haptic feedback to the touchscreen interface will help to improve the user experience in all of these areas. This paper describes the initial outcomes of a study to(More)

Touchscreen interfaces are increasingly used on a daily basis in both mobile devices and in cars. The majority of vehicles use resistive touchscreens which, while reliable and inexpensive, may not perform as well as alternative touchscreen technologies. A simulator-based user-centred study was conducted to compare the User Experience of resistive(More)
Fundamental to any ballistic armour standard is the reference projectile to be defeated. Typically, for certification purposes, a consistent and symmetrical bullet geometry is assumed, however variations in bullet jacket dimensions can have far reaching consequences. Traditionally, characteristics and internal dimensions have been analysed by physically(More)
Fundamental to any ballistic armour standard is the reference projectile that is to be defeated. Typically, for certification, consistency of bullet geometry is assumed. Therefore, practical variations in bullet jacket dimensions can have far reaching consequences. Traditionally, internal dimensions have been analysed by physically sectioning bullets – an(More)
Fundamental to any ballistic armour standard is the reference projectile that is to be defeated. Typically, for certification, consistency of bullets is assumed. Therefore, practical variations in bullet jacket dimensions can have far reaching consequences. Traditionally, internal dimensions could only be analysed by cutting bullets which rules out any(More)
It is well known that yaw can affect the penetrative power of armour piercing rounds. To investigate this effect purely experimentally is difficult because the typical ballistic set up does not allow control over the yaw angle of the projectile. In this study, a numerical model is used complementing ballistic experiments for a range of yaw angles. For the(More)
In 1503, two ships part of Vasco da Gamas second armada to India were lost at sea. Archaeologists followed the historical trail that led them to the wreck site in Ghubbat ar Rahib Bay off Al Hallaniyah Island, Oman. The excavation found over 2800 artefacts including a ships bell and a concretion of silver coins. In this study the use of X-ray Computed(More)
