“…Much of the previous work on developing wearable technology has focused on 'job aids', i.e., presentation of a list of task steps together with the necessary documentation and images needed to complete a procedure, and the opportunity to enter data related to that procedure 14 . Some studies have shown that using a wearable computer to provide such information leads to faster, more efficient performance than using paper 1,2,3 ; whilst other studies have suggested the opposite 18,4 .…”

T he MsSAM project focuses on forensic practice, from the perspective of distributed cognition 6 and its application to crime scene investigation. The research analyses the process of completing crime scene tasks and objectives, the supporting framework within which the practitioner is required to perform, and the human factor elements that affect the Crime Scene Investigator (CSI). Through understanding and analysing the process of crime scene investigation, a theory of technological support has been produced. The theory of technological support to crime scene investigation supports the design and development of novel wearable technology.The following paper outlines the potential capabilities of wearable technology and its application to crime scene investigation. Beginning with the methods used to gather data on the work of the CSI, it will focus on the data capture, recording and disseminative requirements, and also look at how specific research into wearable applications has been utilised to create a multifaceted system that conforms to the requirements of the forensic practitioner. Understanding integration requirementsThe specific application of novel technology needs to provide the necessary capabilities to complete the desired tasks. Therefore, prior to novel technological integration a full understanding of existing practice and of the system, within which integration is to be made, is required. The tasks and objectives of the CSI are varied, requiring the correct methods of search, recovery and preservation of forensic evidence at a variety of scenes.The CSI employs a range of skills that, under usual circumstances, incorporates the search and recording of the scene's physical appearance, correct methods of forensic recovery and finally a fingerprint examination. In conjunction with this, the scene needs to be appropriately recorded and the origin of recovered evidence needs to be fully accounted for. The importance of scene recording is further necessitated by the demands of the Law Courts. Much of the information acquired by the CSI is further utilised by an array of specialist teams, both internal police departments and external organisations, who require the information to complete their specific tasks.

“…Additionally, the presentation of such cues are often associated as representing characteristics of importance and reliability (Berg, 1990;Montgomery & Sorkin, 1996). In the design of augmented reality displays, there is evidence that the compellingness of an information source can be induced by: (1) superimposing information at the same location (Fadden, Ververs, & Wickens, 1998;McCann, Foyle, & Johnston, 1992;National Research Council, 1997;Wickens & Long, 1995), (2) presenting highly accurate attentional guidance (cueing) information (Yeh, Wickens, & Seagull, 1998;Ockerman & Pritchett, 1998), and (3) increasing the apparent realism of the imagery by presenting information using an immersed perspective (Olmos, Wickens, & Chudy, 1997;. We consider each of these potential sources of increased compellingness below and examine their effects on the calibration of attention.…”

“…In the field of medical imaging, doctors can view a virtual image of their patient's internal organs superimposed on the patient's body using an HMD (Rolland, Biocca, Barlow, & Kancerla, 1995) and in the field of aircraft inspection, HMDs provide hands free operation for a mobile operator performing tasks requiring high information content (Ockerman & Pritchett, 1998).…”

“…When a cue (e.g., an arrow pointing the location of a target) is used to orient attention, operators may inappropriately allocate attention to the cued location and fail to attend to sources of information that while uncued, are still relevant (Ockerman & Pritchett, 1998;Yeh, Wickens, & Seagull, 1998). This is a display enhancement we now examine in greater detail.…”

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number. ABSTRACTThis experiment seeks to examine the relationship between three advanced technology features (presentation of target cueing -and the reliability of that data, image reality, and interactivity) and the attention and trust provided to that information. In particular, we investigate the nature of two sorts of biases: an attention bias, in which the operator focuses attention to an area highlighted by the automation at the expense of other areas of the visual scene, and a trust bias, in which unwarranted attention is given to the guidance information.Sixteen military personnel searched for targets camouflaged in terrain, presented at two levels of scene detail (manipulated by varying the number of polygons with which the scene was generated and the level of the detail with which the scene was textured) while performing a terrain association task. Half the subjects actively navigated through the terrain; the other half passively viewed the control path of an active navigator. Cueing was presented for some of the targets, and the reliability of this information was manipulated at two levels (100% and 75%). More importantly, there were objects in the environment that were of high priority and uncued, and detection of these targets provided an assessment as to the degree of an operator's reliance on the cueing information. To assess trust in the terrain simulation, subjects were asked to perform terrain association given a hand-held paper map and report any inconsistencies between the visualization and the map.The results showed that the presence of cueing aided the target detection task for expected targets but drew attention away from the presence of unexpected targets in the environment. Cueing benefits and attentional tunneling were both reduced when cueing became less reliable. Unfortunately, despite knowing that the cue was only partially reliable, subjects still trusted the cue more than was warranted as evidenced by an increased false alarm rate, a drop in sensitivity, and a risky criterion shift. The degree of this change in sensitivity was so great that the loss of reliability in the cue eliminated the benefits of cueing.Finally, neither image reality nor interactivity directly influenced trust...

“…Alternately, MIThril, a complete wearable platform [11], has been developed to facilitate the development of distributed real-time multimodal and context-aware applications. Used in conjunction with the WearARM [12], a wearable computing core, researchers are trying to build a high-performance wearable system that is truly wearable and unobtrusive. For every wearable implementation, one must always choose a tradeoff between bulkiness and performance.…”

Abstract. Disorientation induced by G-forces during aerobatic flight generates difficulties for the pilots to perfectly align their aerobatic maneuver. This paper presents a modular wearable system for enhancing training of aerobatic pilots. A combination of accelerometers and a gyroscope is used to detect possible deviations compared to the optimum trajectory. The wearable system informs the user in real time about the corrections to apply via vibrotactile actuators and speech synthesis. This publication presents a work in progress in order to validate the system in simulation.
