Smart glasses are autonomous and efficient computers that can perform complex tasks through mobile applications. This paper focuses on text input for mobile context. We present a new connected fabric to smart glasses as a device for text entry. This device, integrated into clothing, provides a new interaction technique called TEXTile. It allows typing without requiring users to hold a device. Users can put fingers anywhere on the fabric surface and release them, without needing to look at the fabric or using markers on the fabric. The text entry technique is based on eight combinations of fingers in contact or released, identified as pleasant among 15 in a survey involving 74 participants. A first user's study with 20 participants establishes that the eight combinations for TEXTile were significantly reliable (98.95% recognition rate). A second study with nine participants evaluates the learning curve of TEXTile. Users achieved a mean typing of 8.11 WPM at the end of ten 12-minute sessions, which can be slow, but sufficient with short text compared to other advantages of the technique. Results show low error rates for tasks completed and good usability (76% in SUS questionnaire). The NASA-TLX questionnaire establishes there is no important mental or physical workload to accomplish the task.
Abstract-With the evolution of mobile technology, many devices are introduced with very limited screen sizes like smart glasses. This technology must be accompanied with new visualization techniques. A classic interface can't meet the expectations of the user who becomes increasingly hard to please. The challenge is to display information and allow the user a better navigation with less effort especially in situation of mobility. This paper explores a fisheye view on tiled user interfaces for smart glasses that uses the semantic relationships of items of information contained in the tiles. We propose a reformulation of the degree of interest function and a semantic model for tiled interfaces that supports this reformulation. We developed a prototype to demonstrate the feasibility of our approach and to improve our design approach in our future work.

The focus of this research is to develop and test a new smart glasses application for use in the medical intensive care unit (MICU) to support workflow, patient care, and overall clinical decision-making. The application prototype, mCARE glass, provides clinicians mobility, portability, and hands-free access to real-time patient electronic medical records and bedside data on demand. Five MICU physician volunteers participated in a study consisting of two parts: 1) a usability test with two tasks, and 2) an interview. Part one included usability testing with the use of the tracking pad, followed by the NASA Task Load Index Test and System Usability Scale test. Our findings suggest that mCARE glass has the potential to enhance clinical workflow in the ICU, and that besides providing easy access to patient data, it would improve patient monitoring and surveillance. Participants concurred that for mCARE glass to optimize clinical workflow, it must be well-integrated into one’s daily work as part of decision-making and observation.
Dans ce papier, nous proposons un espace de conception à huit dimensions afin de fournir un cadre pour guider les futurs concepteurs d'applications permettant d'accéder au dossier d'un patient. Les dimensions de notre espace de conception sont tirées de la méthode 5W1H utilisée pour la collecte des informations. Quelques systèmes existants sont ensuite analysés à travers notre espace de conception afin de montrer les manques dans la visualisation des dossiers des patients comme potentiel de nos futurs travaux. ___________________________
