- We present LabDesignAR, an augmented reality application to support the planning, setup, and reconfiguration of marker-based motion capture systems with multiple cameras. LabDesignAR runs on the Microsoft HoloLens and allows the user to place an arbitrary number of virtual "holographic" motion capture cameras into an arbitrary space, in situ. The holographic cameras can be arbitrarily positioned, and different lens configurations can be selected to visualize the resulting fields of view and their intersections. LabDesignAR also demonstrates a hybrid natural gestural interaction technique, implemented through a fusion of the vision-based hand tracking capabilities of an augmented reality headset and instrumented gesture recognition with an electromyography armband. The source code for LabDesignAR and its supporting components can be found online.

- BACKGROUND: Patients with cleft lip and/or palate can undergo numerous procedures to improve appearance, speech, dentition and hearing. We developed a cleft-specific patientreported outcome instrument to facilitate rigorous international measurement and benchmarking. METHODS: Data were collected from patients aged 8-29 years with cleft lip and/or palate at 30 hospitals in 12 countries between October 2014 and November 2016. Rasch measurement theory analysis was used to refine the scales and to examine reliability and validity. Normative CLEFT-Q values were computed for age, sex and cleft type. RESULTS: Analysis led to the refinement of an eating and drinking checklist and 12 scales measuring appearance (of the face, nose, nostrils, teeth, lips, jaws and cleft lip scar), health-related quality of life (psychological, social, school, speech distress) and speech function. All scales met the requirements of the Rasch model. Analysis to explore differential item functioning by age, sex and country provided evidence to support the use of a common scoring algorithm for each scale for international use. Lower (worse) scores on CLEFT-Q scales were associated with having a speech problem, being unhappy with facial appearance, and needing future cleft-related treatments, providing evidence of construct validity. Normative values for age, sex and cleft type showed poorer outcomes associated with older age, female sex and having a visible cleft. INTERPRETATION: The CLEFT-Q represents a rigorously developed instrument that can be used internationally to collect and compare evidence-based outcomes data from patients aged 8-29 years of age with cleft lip and/or palate.

Translation and cultural adaptation of the CLEFT-Q into Arabic, Dutch, Hindi, Swedish, and Turkish

Journal article (peer-reviewed)abstract
- Background: Treatment for cleft lip and/or palate (CL/P) involves a multidisciplinary team of experts who aim to improve ones’ appearance, health-related quality of life, and speech function. To appropriately measure outcomes in CL/P from the patient perspective, a CL/P-specific patient-reported outcome (PRO) instrument is needed. The CLEFT-Q is a self-report PRO instrument developed to evaluate treatment outcomes in patients with CL/P. The aim of this study was to translate and culturally adapt the CLEFT-Q. Methods: The CLEFT-Q was translated and culturally adapted from English into Arabic, Dutch, Hindi, Swedish, and Turkish using guidelines set forth by the International Society for Pharmacoeconomics and Outcomes Research. For each language, two forward translations, one back translation, and cognitive debriefing interviews with patients were conducted. Results: The field test version of the CLEFT-Q consisted of 154 items across 13 scales. Forward translations for each language revealed few items that were difficult to translate into the various languages. Comparison of each back translation to the English version identified that a change in the meaning of an item was more common in the Turkish (n = 40, 26%) and Arabic (n = 17, 11%) translations, and required re-translation. Cognitive debriefing interviews involved 41 participants from plastic surgery centers in India, Qatar, Sweden, the Netherlands, and Turkey. Participants reported few difficulties in understanding the items, instructions, and response options in each CLEFT-Q translation. Conclusions: Semantic, idiomatic, experiential, and conceptual equivalence of the CLEFT-Q was achieved for all language versions, thus providing evidence of the CLEFT-Q’s transferability to other languages and cultures. Level of Evidence: Not ratable
