Abstract This paper develops a physical model of an inertial/magnetic measurement unit by effectively integrating an accelerometer, a magnetometer, and two gyroscopes for low-g motion tracking applications. The proposed model breaks down the errors contributed by individual components, then determines error elimination methods based on sensor behavior and characteristics, and finally constructs a feedback loop for continuous self-calibration.

Abstract The elderly represent a valid group of users who can potentially benefit greatly from engaging with technology, such as healthcare systems or playing digital games. Yet, less attention has been given to the significance of senior citizens as technology users, as compared to the common younger population. In an effort to fill in the gap, this workshop aims to investigate the design of technology for senior citizens.

ABSTRACT We have demonstrated that balance disturbance induced by scene motion can be reduced using an independent visual background (IVB). It has been theorized that the human vision system can divided into two functional systems, and that the visual periphery mediates spatial orientaiton Therefore, we hypothesized that an IVB located in the peripheral field would be more effective than one located centrally.

Abstract A conceptual model of product emotion was developed considering the pre-purchase context. The main proposition of this model is that affect generated in the pre-purchase context is a result of product evaluation using consumergenerated criteria. The process starts when a consumer becomes interested in the distinctive, integrative and interactive features of a product. A survey was conducted to determine the criteria used by consumers when buying clothes, watches, and electronic products.

Abstract Although Augmented Reality technology was first developed over forty years ago, there has been little survey work giving an overview of recent research in the field. This paper reviews the ten-year development of the work presented at the ISMAR conference and its predecessors with a particular focus on tracking, interaction and display research.

Abstract We propose a novel mobile AR (Augmented Reality) application that uses a microscopic interaction prototype called NanoAR. A user can view the AR content using a USB or an iPhone microscope via NanoAR. The objects that the user can view using this application are related to the magnification rate; in other words, the application resembles a microscope in the real world. This indicates that a user can view two different objects on the same spot of the paper.

Abstract This paper presents a new sensing system for home-based rehabilitation based on optical linear encoder (OLE), in which the motion of an optical encoder on a code strip is converted to the limb joints' goniometric data. A body sensing module was designed, integrating the OLE and an accelerometer. A sensor network of three sensing modules was established via controller area network bus to capture human arm motion.

Abstract In this paper we explore the motion control of a robotic puppet through motion capture data. A motion mapping technique is investigated to map the human motion into marionette motion, and from that calculate the rotation of the servo motors to achieve desired marionette motions. A software was developed to capture human motions utilizing a bend-twist sensor system, and use the motion data to control the robotic marionette by either offline control method or online control method (real-time).

Simulator sickness (SS)-virtual environment (VE) sickness is expected to become increasingly troublesome as VE technology evolves. This paper investigated using an independent visual background (IVB) to reduce SS and VE sickness. The IVB is a visual scene component that provides visual motion and orientation cues that match those from the vestibular receptors. In this study, the IVB was stationary, fixed with respect to inertial space. Two experiments were conducted. The first experiment examined the differences in visual ...

This study aims to characterize the communication patterns of Filipino pilots in the cockpit and assess its adherence to CRM principles of assertiveness, openness, conflict resolution, and communication effectiveness. A survey was administered to 88 participants who are mostly captains and first officers. Filipino captains and first officers generally have the same attitude that corresponds to the principles learned in CRM training on communication and coordination. However, a detailed comparison of the groups' responses showed ...

The Pre-purchase Affect Model (PAM) was developed. It predicts how product criteria for purchase may engender affect. A field survey was conducted to determine what criteria consumers use to purchase electronic products and items of clothing. A total of 23 and 21 criteria were identified for buying clothing and electronic products, respectively. There were 11 types of criteria for clothes and nine for electronic products. The criteria were compared with the product attributes. If there was a match pre-purchase affect resulted. The use of ...

Abstract The present study investigated the role of encoding perspective in mental representation for the spatial layout learned via the route, leaning and aerial perspectives which are different with respect to the height taken. Two experiments with the same procedures were carried out in two different virtual rooms. The results showed that the direction judgment, especially the vertical angle judgment, was changed as the perspectives varied along the vertical dimension of space. In addition, the room geometry can also ...

Abstract Massive Multiplayer Online Games (MMOG) allows a large number of players to cooperate, compete and interact meaningfully in the online environment. Gamers are able to form social network with fellow gamers and create a unique virtual community. Although research has discussed the importance of social interaction in MMOG, it fails to articulate how social interaction takes place in the game. The current chapter aims to depict how gamers interact and socialize with each other in a popular MMOG, World of Warcraft. ...

Subjects in the experiment reported observed the same spatial layout in the rectangular room and the cylindrical room from the exocentric (45 ) perspective first and then the egocentric (0 ) perspective. The mental representations of space were testified by the judgment of relative direction between objects. The results showed that subjects represented the spatial horizontal relation more accurately along the imagined direction that paralleled to the wall in the rectangular room but along the imagined direction that was ...

Abstract Postural disturbance following virtual environment (VE) exposure has been reported in many studies. Some suggest that postural disturbance could be a pre-cursor of or highly related to simulator sickness (SS). Few studies have addressed long duration exposure and multi-sessions in SS and postural disturbance. This study investigated effects of long duration and repeated exposure to an immersive VE on postural disturbance. The results suggested larger postural disturbance 24 hours and 48 hours after the first VE ...
