We describe the design of a low temperature scanning Hall probe microscope (SHPM) for a dilution refrigerator system. A detachable SHPM head with 25.4 mm OD and 200 mm length is integrated at the end of the mixing chamber base plate of the dilution refrigerator insert (Oxford Instruments, Kelvinox MX-400) by means of a dedicated docking station. It is also possible to use this detachable SHPM h...

Head coupled perspective is often considered to be an essential aspect of stereoscopic desktop virtual reality (VR) systems. Such systems use a tracking device to determine the user’s head pose in up to six degrees of freedom (DOF). Users of desktop VR systems perform their task while sitting down and therefore the extent of head movements is limited. This paper investigates the validity of usi...

Children with autism have specific difficulties understanding complex mental states like thought, belief, and false belief and their effects on behaviour. Such children benefit from focused teaching, where beliefs are likened to photographs-in-the-head. Here two studies, one with seven participants and one with 10, tested a picturein-the-head strategy for dealing with thoughts and behaviour by ...

Posturographic measurements using a piezoelectric platform were made in normal subjects while wearing a combination of spectacle and contact lens providing partial stabilisation of the retinal image (RIS). The amount of postural sway seen while wearing the device at rest is intermediate between the "normal vision" and "eyes closed" conditions, and increases with increasing amounts of RIS. Howev...

In telexistence master–slave systems, it is important to transmit visual information from remote places to the operator. Conventional imaging devices in head-mounted displays (HMDs) can only express the three-axis rotation of the neck. However, humans can obtain broader visual fields and motion parallax information from the translational motion of their necks. We have proposed a system that can...

Computer interfaces such as mouse, track balls, and light pens etc. provide users with a way of controlling and manipulating the display of information on a computer screen. Although a mouse is popular and effective it has disadvantages typically in the circumstances where; ⇛ The user wants to use hands for other purpose, e.g., the user wants to use keyboard for typing simultaneously. ⇛ The use...

Augmented Reality systems overlay computer generated information onto a user’s natural senses. Where this additional information is visual, the information is overlaid on the user’s natural visual field of view through a head mounted (or “head-up”) display device. Integrated Home Systems provides a network that links every electrical device in the home which provides to a user both control and ...

The emerging station-free bike sharing schemes create large quantities of spatiotemporal data and provide opportunities for urban and transportation studies. These schemes are different from traditional city rental schemes (they have no docking stations, etc.). They have at their core a continuous GPS system and generate large amounts of spatially located data for each bike. This study proposes...

The assessment of nociceptive thresholds is employed in animals and humans to evaluate changes in sensitivity potentially arising from tissue damage. Its application on the intact pig tail might represent a suitable method to assess changes in nociceptive thresholds arising from tail injury, such as tail docking or tail biting. The Pressure Application Measurement (PAM) device is used here for ...
