The purpose of this study was to gather usability data on a new flight deck concept in which pilots are shown certified and uncertified information concurrently on installed avionics. Specifically, we wanted to examine perceptions on the concepts of concurrent use and differentiation for electronic flight bag (EFB) applications that show ownship position. We presented an uncertified electronic chart on either a portable electronic device (PED) alone (off to the pilot’s side) or on both a PED and an installed flight deck display. The uncertified electronic chart was always shown concurrently with an approved navigation source. We differentiated the electronic chart from the navigation information via display medium (portable vs. installed) and a header labeled “EFB,” drawn at the top of the uncertified electronic chart on the installed display. Thirteen flightcrews flew eight scenarios using the flight deck concept. Pilots liked the concurrent display of the electronic chart, and the repeated display functionality, in particular, because they could control the presentation of information on the forward display using the touch screen on the side display. Our method of differentiation—a header—was less successful and suggests a need to consider the potential for stimulus habituation when evaluating these techniques.

Instrumented usability analysis involves the use of sensors during a usability study which provide observations from which the evaluator can infer details of the context of use, specific activities, or disturbances. This is particularly useful for the evaluation of mobile and wearable devices which are currently difficult to test realistically without constraining users in unnatural ways. To illustrate the benefits of such an approach, a study of touch-screen selection of on-screen targets is presented whilst walking and sitting, using a PocketPC instrumented with an accelerometer. From the accelerometer data, the user’s gait behaviour is inferred, allowing linking performance to gait phase angle, showing there were phase regions with significantly lower error and variability. The chapter provides examples of how information acquired via sensors gives quantitatively measurable information about the detailed interactions taking place when mobile, allowing designers to test and revise design decisions, based on realistic user activity.

Background Certolizumab pegol (CZP) is an anti-tumor necrosis factor drug approved for the treatment of multiple moderate to severe chronic inflammatory diseases. In the European Union, CZP is approved for administration by subcutaneous self-injection using a prefilled syringe, prefilled pen, or reusable electromechanical auto-injector (electronic device). CimplyMe is a companion app for use alongside CZP self-injection devices, designed to support CZP-treated patients self-managing their treatment and disease. Objective This study aimed to validate the usability of the companion app by demonstrating that tasks required for use can be performed successfully by intended end users. Methods We recruited 15 patients with moderate to severe rheumatoid arthritis, currently prescribed biologic treatment, and using apps on a smart phone. Patients were assessed on their ability to use the companion app in a setting designed to simulate a location where patients regularly administer biologic treatment. To assess the usability of the key features of the app, 8 critical and 3 noncritical tasks were designed. Patients’ success on each task was recorded through observations or knowledge-based questions. Successes with difficulty and use errors were also recorded. If a patient made a use error at the first attempt, a second attempt was allowed. Second-attempt use errors were recorded as a task failure. Results A total of 207 first attempts at the 14 components of the 8 critical tasks were evaluated (3 patients failed to complete one component); 178 (86.0%) critical tasks were successfully completed at the first attempt. The remaining first attempts comprised 16 (7.7%) successes with difficulty and 13 (6.3%) use errors, which had to be repeated. One critical task was not re-attempted by one patient due to time constraints; however, there were no use errors in the 12 completed second attempts. A total of 107 first attempts at the 3 noncritical tasks were made, all of which (107/107, 100.0%) were completed without use errors. Conclusions In simulated testing, patients were able to successfully use the companion app without formal training. This study suggests the companion app is easy to use and could help patients prescribed CZP better manage their treatment and disease.

Abstract The paper presents an analysis of the operation process of the selected electronic device (ED) like tablet type X. The damage of ED is caused by environmental exposure or use contrary to the applicable operating instructions. The damage initiates the process of changing many or one of the usable features of a specific ED. This usually leads to damage, i.e. changes in the properties of components of a specific ED (e.g. touch screen, compact systems, resistors, capacitors, battery cells, etc.). The basic operational indicators of the ED were determined based on the analysis of the type of damage to all devices that were reported to the service center – 2 391 notifications. The research was carried out on the company’s website, and the duration was 15 months from the time of the introduction of the ED to the market.

Introduction: The current work probes the effectiveness of multimodal touch screen tablet electronic devices in conveying science, technology, engineering, and mathematics graphics via vibrations and sounds to individuals who are visually impaired (i.e., blind or low vision) and compares it with similar graphics presented in an embossed format. Method: A volunteer sample of 22 participants who are visually impaired, selected from a summer camp and local schools for blind students, were recruited for the current study. Participants were first briefly (∼30 min) trained on how to explore graphics via a multimodal touch screen tablet. They then explored six graphic types (number line, table, pie chart, bar chart, line graph, and map) displayed via embossed paper and tablet. Participants answered three content questions per graphic type following exploration. Results: Participants were only 6% more accurate when answering questions regarding an embossed graphic as opposed to a tablet graphic. A paired-samples t test indicated that this difference was not significant, t(14) = 1.91, p = .07. Follow-up analyses indicated that presentation medium did not interact with graphic type, F(5, 50) = 0.43, p = .83, nor visual ability, F(1, 13) = 0.00, p = .96. Discussion: The findings demonstrate that multimodal touch screen tablets may be comparable to embossed graphics in conveying iconographic science and mathematics content to individuals with visual impairments, regardless of the severity of impairment. The relative equivalence in response accuracy between mediums was unexpected, given that most students who participated were braille readers and had experience reading embossed graphics, whereas they were introduced to the tablet the day of testing. Implications for practitioners: This work illustrates that multimodal touch screen tablets may be an effective option for general education teachers or teachers of students with visual impairments to use in their educational practices. Currently, preparation of accessible graphics is time consuming and requires significant preparation, but such tablets provide solutions for offering “real-time” displays of these graphics for presentation in class.
