Colorblind people or people with a color vision deficiency have to face many challenges in their daily activities. Their disadvantage to perceive colors incorrectly leads to frustration when determining the freshness of fruits and the rawness of meat as well as the problem to distinguish clothes with confusing colors. With the rise of the smartphone, numerous mobile applications are developed to overcome those problems, improving the quality of live. However, smartphones also have some limitations in certain use cases. Especially activities where both hands are needed do not suit well for smartphone applications. Furthermore, there exist tasks in which a continuous use of a smartphone is not possible or even not legally allowed such as driving a car. In recent years, fairly new devices called smart glasses become increasingly popular, which offer great potential for several use cases. One of the most famous representatives of smart glasses is Google Glass, a head-mounted display that is worn like normal eyeglasses produced by Google. This paper introduces an experimental prototype of a Google Glass application for colorblind people or people with a color vision deficiency, called OmniColor and meets the challenge if Google Glass is able to improve the color perception of those people. To show the benefits of OmniColor, an Ishihara color plate test is performed by a group of 14 participants either with, or without the use of OmniColor.

Smart Glasses

Observation of surgical procedures performed by experts is extremely important for acquisition and improvement of surgical skills. Smart glasses are small computers, which comprise a head-mounted monitor and video camera, and can be connected to the internet. They can be used for remote observation of surgeries by video streaming. Although Google Glass is the most commonly used smart glasses for medical purposes, it is still unavailable commercially and has some limitations. This article reports the use of a different type of smart glasses, InfoLinker, for surgical video streaming. InfoLinker has been commercially available in Japan for industrial purposes for more than 2 years. It is connected to a video server via wireless internet directly, and streaming video can be seen anywhere an internet connection is available. We have attempted live video streaming of knee arthroplasty operations that were viewed at several different locations, including foreign countries, on a common web browser. Although the quality of video images depended on the resolution and dynamic range of the video camera, speed of internet connection, and the wearer’s attention to minimize image shaking, video streaming could be easily performed throughout the procedure. The wearer could confirm the quality of the video as the video was being shot by the head-mounted display. The time and cost for observation of surgical procedures can be reduced by InfoLinker, and further improvement of hardware as well as the wearer’s video shooting technique is expected. We believe that this can be used in other medical settings.

About 250 million people in the world suffer from color vision deficiency (CVD). Contact lenses and glasses with a color filter are available to partially improve the vision of people with CVD. Tinted glasses uniformly change the colors in a user’s field of view (FoV), which can improve the contrast of certain colors while making others hard to identify. On the other hand, an optical see-through head-mounted display (OST-HMD) provides a new alternative by applying a controllable overlay to a user’s FoV. The method of color calibration for people with CVD, such as the Daltonization process, needs to make the calibrated color darker, which has not yet been featured on recent commercial OST-HMDs. We propose a new approach to realize light subtraction on OST-HMDs using a transmissive LCD panel, a prototype system, named ALCC-glasses, to validate and demonstrate the new arriving light chroma controllable augmented reality technology for CVD compensation.

Abstract Progressively, smartphones have become the pocket Swiss army knife for everyone. They support their users needs to accomplish tasks in numerous contexts. However, the applications executing those tasks are regularly not performing as they should, and the user-perceived experience is altered. In this paper, we present our approach to model and predict the Quality of Experience (QoE) of mobile applications used over WiFi or cellular network. We aimed to create predictive QoE models and to derive recommendations for mobile application developers to create QoE aware applications. Previous works on smartphone applications’ QoE prediction only focus on qualitative or quantitative data. We collected both qualitative and quantitative data “in the wild“ through our living lab. We ran a 4-week-long study with 38 Android phone users. We focused on frequently used and highly interactive applications. The participants rated their mobile applications’ expectation and QoE and in various contexts resulting in a total of 6086 ratings. Simultaneously, our smartphone logger (mQoL-Log) collected background information such as network information, user physical activity, battery statistics, and more. We apply various data aggregation approaches and features selection processes to train multiple predictive QoE models. We obtain better model performances using ratings acquired within 14.85 minutes after the application usage. Additionally, we boost our models’ performance with the users expectation as a new feature. We create an on-device prediction model with on-smartphone only features. We compare its performance metrics against the previous model. The on-device model performs below the full features models. Surprisingly, among the following top three features: the intended task to accomplish with the app, application’s name (e.g., WhatsApp, Spotify), and network Quality of Service (QoS), the user physical activity is the most important feature (e.g., if walking). Finally, we share our recommendations with the application developers, and we discuss the implications of QoE and expectations in mobile application design.

BACKGROUND There are an increasing number of mobile applications that provide dietary guidance in supporting healthy lifestyle and disease management. However, the characteristics of these nutrition-related apps are not well analyzed. OBJECTIVE This study aimed to evaluate the functionality and quality of nutrition-related apps in China. METHODS Mobile apps providing dietary guidance were screened in Chinese iOS and android app stores using stepwise searching criteria in November 2017. Primary review was conducted by extracting information from the description of apps. Free apps that contain all the information of diet and nutrition, with the last update after 1st Jan 2016 were downloaded for further analysis on the nutritional functionality features based on the framework of Chinese Dietary Guidelines and on the market related features as well. The user version of the Mobile Application Rating Scale (uMARS) was used to assess the quality of apps. RESULTS Among the 44 downloaded nutrition-related apps screened from 628 apps with dietary guidance content, only 11(25%) were aimed exclusively for dietary guidance, the others were aimed for fitness guidance (17, 39%), disease management (11, 25%) and maternal health (5, 11%) respectively. The nutritional functionalities of the 44 apps included nutritional information enquiry (40, 91%), nutrition education (35, 80%), food record (34, 77%), diet analysis (34, 77%), and personalized recipes (21, 48%). Twelve out of 44 apps contained all of the above five nutrition related functionalities. The diet analysis and suggestions were mainly focused on energy (33/44, 75%), less on other factors like dietary structure (10/44, 23%). About 96% (42/44) of the apps provided social communication functionality and 59% (26/44) of the apps supported user incentives. Eight out of 44 apps (18%) also applied intelligent recognition technology. Using 5-point uMARS as scales of quality, the median scores of the 44 apps was 3.6 (IQR = 0.7). CONCLUSIONS Most nutrition-related apps are developed in the service of health management other than for dietary guidance exclusively. Although basic energy balance theory was generally applied, the nutritional functionality of the nutrition-related apps is relatively limited and not individualized. More efforts should be taken to integrate with the scientific nutritional knowledge and innovative technology in developing an app followed with complete and personalized dietary guidance.

Major Public Health Problem

BACKGROUND Diabetes mellitus is currently a major public health problem worldwide. It is traditionally approached in a clinical inpatient relationship between the patient and the healthcare professional. However, the rise of new technologies, particularly mobile applications, is revolutionizing the traditional healthcare model through the introduction of telehealthcare. OBJECTIVE (1) To assess the effects of mobile applications for improving healthy lifestyles on the quality of life and metabolic control of diabetes mellitus in adult patients. (2) To describe the characteristics of the mobile applications used, identify the healthy lifestyles they target, and describe any adverse effects their use may have. METHODS Review of systematic reviews and meta-analysis, following the guidelines of the Cochrane Collaboration and the Joanna Briggs Institute. We included studies that used any mobile application aimed at helping patients improve self-management of diabetes mellitus by focusing on healthy lifestyles. Studies needed to include a control group receiving regular care without the use of mobile devices. In May 2018, a search was conducted in Medline, Embase, Cochrane, LILACS, PsychINFO, Cinahl and Science Direct, updated in May 2019. The methodological quality of the studies was assessed using the Amstar-2 tool. RESULTS Seven systematic reviews of 798 articles were initially selected for analysis. The interventions had a duration of between 1 and 12 months. Mobile applications focused singly or simultaneously on different lifestyles aspects (diet, physical exercise, motivation, blood glucose levels, etc.). There are significant changes in HbA1c values, body weight and BMI, although in others, such as lipid profile, quality of life, or blood pressure, there is no clear improvement. CONCLUSIONS There is clear evidence that the use of mobile applications improves glycemic control in diabetic patients in the short term. There is a lack of evidence in its long-term benefits. It is thus necessary to carry out further studies to learn about the long-term effectiveness of mobile applications aimed at promoting the healthy lifestyles of diabetic patients.

Attempts to optimize monitoring of brace adherence prescribed to adolescents with idiopathic scoliosis (IS) have generally relied on sensors. Sensors, however, are intrusive and do not allow the assessment of psychological and physical consequences of brace use that might underlie poor adherence. Mobile applications have emerged as alternatives to monitor brace compliance. However, the feasibility and utility of these app-based systems to assess key psychological and physical domains associated with non-adherence remain unexplored. This feasibility study aims to test the usability, acceptability, and clinical utility of an app-based system that monitors brace use and related psychological and physical factors. Forty adolescents with IS daily respond to the app for 90 days. The patient responses may generate clinical alarms (e.g., brace non-adherence, discomfort, or distress) that will be sent daily to the medical team. Primary outcomes will be app usability, acceptability, and response rates. Secondary outcomes will include brace adherence, the number of side effects reported, number and type of clinical alarms, stress, quality of life, perceived health status, and mood. If accepted by patients and clinicians, apps may allow rapid detection and response to undesired events in adolescents undergoing brace treatment.
