Abstract Manual palpation (MP) is commonly used for the assessment of patients with neuromusculoskeletal dysfunction. During assessment of lumbo-pelvic disorders in particular, it may be used not ...only to explore pain and resistance in the region, but also to evaluate the symmetry and movement quality of the area. Whilst reliability of MP has been extensively investigated, its validity remains relatively under researched. The aim of this study was to explore the accuracy of MP of lumbo-pelvic bony points. Ultrasound images of three bony landmarks 4th lumbar spinous process (L4), left and right posterior superior iliac spines (PSIS) were acquired from models ( n = 3) in the prone position and the points marked with an ultra-violet (UV) pen. Nine musculoskeletal physiotherapists were asked to identify the bony landmarks using MP. Measurements (mms) were taken between the UV marks and the palpators’ marks. The mean error (standard deviation) (mm) for MP of L4, LPSIS, RPSIS were 15.63 (3.89), 20.07 (4.60), 20.59 (2.79) respectively. Bland and Altman analysis gave a mean value of 0.173, with 95% limits of agreement ranging from −27.8 to 26.3. This study suggests that MP of specific lumbo-pelvic bony points has limited validity.

On Monday, 15 July 1991, prior to the Ninth National Conference on Artificial Intelligence (AAAI‐91) in Anaheim, California, over 50 scientists and engineers attended the AAAI‐91 Workshop on ...Intelligent Multimedia Interfaces. The purpose of the workshop was threefold: (1) bring together researchers and practitioners to report on current advances in intelligent multimedia interface systems and their underlying theories, (2) foster scientific interchange among these individuals, and (3) evaluate current efforts and make recommendations for future investigations.

This article summarizes the main results of a joint endeavor towards a standard reference model (SRM) for intelligent multimedia presentation systems (IMMPSs). After a brief motivation, we give basic ...definitions for
media terms and
presentation systems. The core of this contribution is a generic reference architecture that reflects an implementation-independent view of the processes required for the generation of multimedia presentations. The reference architecture is described in terms of
layers, components, and
knowledge servers. Our SRM focuses on the
functions assigned to the layers and components, rather than on the methods or communication protocols that may be employed to realize this functionality. Finally, we point to some possible extensions of the reference model.

Broadcast news sources and newspapers provide society with the vast majority of real-time information. Unfortunately, cost efficiencies and real-time pressures demand that producers, editors, and ...writers select and organize content for stereotypical audiences. In this article we illustrate how content understanding, user modeling, and tailored presentation generation promise personalcasts on demand. Specifically, we report on the design and implementation of a personalized version of a broadcast news understanding system, MITRE's Broadcast News Navigator (BNN), that tracks and infers user content interests and media preferences. We report on the incorporation of Local Context Analysis to both expand the user's original query to the most related terms in the corpus, as well as to allow the user to provide interactive feedback to enhance the relevance of selected newsstories. We describe an empirical study of the search for stories on ten topics from a video corpus. By personalizing both the selection of stories and the form in which they are delivered, we provide users with tailored broadcast news. This individual news personalization provides more fine-grained content tailoring than current personalized television program level recommenders and does not rely on externally provided program metadata.

Aviation systems represent a rich, difficult, and critical environment for usability. The life critical importance of aviation systems complemented by with their complexity and the diversity and ...uncertainty of environments in which they operate, place them necessarily on the avant-guard of usability. We describe the broad range of aviation missions, operators, and operating environments and relate these to key dimensions of usability and visual interfaces. We illustrate this concretely with two case examples: ground control stations for remotely piloted aircraft and air traffic management systems. We explore how in both these cases advances in machine autonomy and human control promise to enhance operator situational awareness and control, however, not without challenges. We share guidelines to ensure effective usability to include: require usability as a key performance parameter, architect and design systems and operations that incorporate affordances and fault tolerance, employ standards to increase learnability and interoperability, instrument environments to tailor usability, and assess effects (Maybury 2012). Finally, remaining challenges and future directions are discussed.
