Use of a sonification system for science learning by people who are blind

Purpose The purpose of this paper is to examine a central need of students who are blind: the ability to access science curriculum content. Design/methodology/approach Agent-based modeling is a relatively new computational modeling paradigm that models complex dynamic systems. NetLogo is a widely used agent-based modeling language that enables exploration and construction of models of complex systems by programming and running the rules and behaviors. Sonification of variables and events in an agent-based NetLogo computer model of gas in a container is used to convey phenomena information. This study examined mainly two research topics: the scientific conceptual knowledge and systems reasoning that were learned as a result of interaction with the listen-to-complexity (L2C) environment as appeared in answers to the pre- and post-tests and the learning topics of kinetic molecular theory of gas in chemistry that was learned as a result of interaction with the L2C environment. The case study research focused on A., a woman who is adventitiously blind, for eight sessions. Findings The participant successfully completed all curricular assignments; her scientific conceptual knowledge and systems reasoning became more specific and aligned with scientific knowledge. Practical implications A practical implication of further studies is that they are likely to have an impact on the accessibility of learning materials, especially in science education for students who are blind, as equal access to low-cost learning environments that are equivalent to those used by sighted users would support their inclusion in the K-12 academic curriculum. Originality/value The innovative and low-cost learning system that is used in this research is based on transmittal of visual information of dynamic and complex systems, providing perceptual compensation by harnessing auditory feedback. For the first time the L2C system is based on sound that represents a dynamic rather than a static array. In this study, the authors explore how a combination of several auditory representations may affect cognitive learning ability.

Acceptance of seniors towards automatic in home fall detection devices

Purpose Senior citizen falls are one of the highest-cost factors of healthcare within this population group. Various approaches for automatic fall detection exist. However, little is known about the seniors’ acceptance of these systems. The purpose of this paper is to investigate the acceptance of automatic fall detection devices as well as the technological commitment and the health status in community-dwelling adults with a predefined risk of falling. Design/methodology/approach Seniors with a risk of falling were equipped with either an accelerometer or an accelerometer with an additional visual and optical fall detection system in a sub-group of the study population for a period of eight weeks. Pre- and post-study questionnaires were used to assess attitudes and acceptance toward technology. Findings In total, 14 subjects with a mean age of 75.1 years completed the study. Acceptance toward all sensors was high and subjects were confident in their ability to handle technology. Medical assessments showed only very mild physical and no mental impairments. Measures that assured subjects privacy protection were welcomed. Sensor technology should be as unobtrusive as possible. Originality/value Privacy protection and uncomplicated use of the fall detection equipment led to high acceptance in seniors with high-technical commitment and good health status. Issues to further improve acceptance could be identified. Future research on different populations is necessary.

Virtual reality and robots for autism: moving beyond the screen

Purpose This short paper reports on the fourth seminar in a seven-seminar series entitled, “Innovative Technologies for Autism: Critical Reflections on Digital Bubbles”, funded by the UK Economic and Social Research Council. The purpose of this paper is to consider in more depth the technologies being developed and used in the autism field, and to critically reflect on their relative benefits and potential pitfalls. Design/methodology/approach Presentations from key researchers and practitioners are reviewed, highlighting contemporary issues in the area of autism and technology. The presentations include descriptions of cutting-edge technologies as well as the role of technology in human-human interaction. Findings Despite its potential, technology for autism is regarded by many with some caution: technology per se cannot provide solutions to key issues in the field. However, by looking in more depth at the features of new technologies and the interactions that take place with and around them, we can begin to build up a picture of best practice around technology for autism. Originality/value This paper offers up-to-date insights from leading academics on the benefits and challenges of innovative technologies in the field of autism research and practice. Specifically, it highlights the importance of including a breadth of expertise in the design of such tools, and the need to consider technology as a means to an end, rather than an end in itself.

PROCEE: a PROstate Cancer Evaluation and Education serious game for African Caribbean men

Purpose Prostate cancer is the most common cancer diagnosed in men in the UK. Black men are in a higher prostate cancer risk group possibly due to inherent genetic factors. The purpose of this paper is to introduce PROstate Cancer Evaluation and Education (PROCEE), an innovative serious game aimed at providing prostate cancer information and risk evaluation to black African-Caribbean men. Design/methodology/approach PROCEE has been carefully co-designed with prostate cancer experts, prostate cancer patients and members of the black African-Caribbean community in order to ensure that it meets the real needs and expectations of the target audience. Findings During the co-design process, the users defined an easy to use and entertaining game which can effectively raise awareness, inform users about prostate cancer and their risk, and encourage symptomatic men to seek medical attention in a timely manner. Originality/value During focus group evaluations, users embraced the game and emphasised that it can potentially have a positive impact on changing user behaviour among high risk men who are experiencing symptoms and who are reluctant to visit their doctor.

Towards full digital inclusion: the ENTELIS manifesto against the digital divide

Purpose The purpose of this paper is to present the work of the European Network for Technology Enhanced Learning in an Inclusive Society project, which addresses the challenges of the digital divide for people with disabilities of all ages. Design/methodology/approach The project employs a number of activities and approaches which involve people with disabilities and other stakeholders, in order collect scientific knowledge, views, suggestions and experiences that will help in bridging the digital divide. These include literature review and qualitative methodologies of data collection, such as interviews with stakeholders, focus groups and living labs. Findings The benefits of (assistive) technology in the lives of people with disabilities are highly appreciated. However, a number of barriers, including lack of digital skills are identified. Thus the development of (assistive) technology competencies programmes is suggested. In addition, there is evidence of the need to further involve all stakeholders and increase awareness. Social implications The most important implication of the project is the production of the manifesto against the digital divide. With this document the project consortium justifies for action on raising awareness regarding the rights of persons with disabilities of all ages to be digitally included. Originality/value The value of the project lies upon the publication of the manifesto against the digital divide, which has already been endorsed by a number of organisations in Europe and elsewhere, with the aspiration of influencing policy makers and practitioners to collaborate in order to bridge the digital divide.

Recognizing voice: the child with autism spectrum disorder

Purpose This paper assesses the ability of the minimally verbal child with autism to recognise their own voice. The rationale for this study rests in recent advances in technology aimed at making the voice of speech generating devices (SGDs) sound more like the child using them (van Santen and Black, 2009). The purpose of this paper is to investigate the child’s ability to actually recognise the sound of their own voice in a series of short experiments using computer-based methodology. Design/methodology/approach Using a voice-face matching computerised paradigm, the performance of 33 children with autism was compared to that of 27 children with developmental delay (DD), and 33 typically developing (TD) children. The children were matched for verbal and non-verbal ability and a training period was conducted prior to the main test to ensure children’s understanding of what was expected of them. Findings The findings of this study suggest that the child with autism recognise the sound of their own voice at test, but with much greater difficulty than age-and-ability matched comparison groups. The implications of this finding are useful for researchers in the field of speech mimicry technology and manufacturers of SGD software packages. The paper also provides empirical insights about how the child with autism may process voice in their everyday social interactions. Research limitations/implications Some limitations to this study exist, for instance, there were only a small number of presentations involving self-voice in this task. This may have over simplified the process for the young TD children and the children with DD. Nevertheless, it is striking that despite being matched for non-verbal mental age, the children with autism performed significantly less well than either of the other two groups of children. However, future studies would benefit from adjusting the number of presentations of voice and face accordingly. It is also important to note that for some children with autism the simultaneous presentation of faces and voices may act more as an interference effect (Cook and Wilding, 1997; Joassin et al., 2004) than a facilitation effect (Molholm et al., 2002). Future studies may wish to test a subgroup on voice recognition without the aid of visual prompts. Practical implications The paper includes implications for the type of voice children with autism may prefer to use when communicating via a SGD. The authors suggest that if the child does not recognise or prefer the sound of their own natural voice on such devices, partial or complete abandonment of the SGD may occur. Originality/value This paper fulfils an identified need to research how children’s abilities and preferences can be taken into account at the point of decision making for particular communication tools.

An instrument to measure mobile shower commode usability: the eMAST 1.0

Purpose The purpose of this paper is to present a preliminary psychometric evaluation of the electronic mobile shower commode assessment tool (eMAST) 1.0. Design/methodology/approach A cross-sectional validation study was undertaken with 32 adults with spinal cord injury (SCI), aged 18 years or older, who use mobile shower commodes for toileting and/or showering. The eMAST 1.0, Quebec user evaluation of satisfaction with assistive technology, Version 2.0 (QUEST 2.0), and modified system usability scale (SUS) were administered online via SurveyMonkey. The eMAST 1.0 was re-administered approximately seven days later. Psychometric properties of internal consistency, test-retest reliability, and convergent validity were assessed. Findings As hypothesised, the eMAST 1.0 demonstrated strong internal consistency (Cronbach’s α=0.73, N=32); acceptable test-retest reliability (intra-class coefficient (3, 1)=0.75 (0.53-0.88, 95 per cent confidence interval) (n=27)); and strong, positive correlations with the QUEST 2.0’s devices subscale and modified SUS (Pearson’s correlation coefficients 0.70 and 0.63, respectively). Research limitations/implications The sample was not fully representative of Australian data in terms of gender, or state of residence, but was representative in terms of SCI level. Age data were not assessed. The sample size was small but adequate for a preliminary psychometric evaluation. Originality/value The preliminary psychometric evaluation indicates the eMAST 1.0 is a valid and reliable instrument that measures usability of MSCs for adults with SCI. It may be useful for exploring relationships between usability and satisfaction of MSCs.

Indoor navigation with smart phone IMU for the visually impaired in university buildings

Purpose The purpose of this paper is to design and test effective indoor navigation solutions for visually impaired people in situations where GPS, bluetooth or Wi-Fi signals are unavailable. The authors use the inertial measurement units (IMU), the compass and the barometer of a smart phone. Design/methodology/approach The authors have used commercial Android smart phones with IMU, compass and barometer to record a path and to give navigation instructions in an adapted way using a mobility-specific vocabulary. The method proposed is to save paths taking into account different indoor waypoints such as the stairs (change from one floor to another) and the change of direction of the trajectory of the path (e.g. one-fourth turn right or left), recording data from the IMU sensor’s, compass and barometer of the smart phone. Having this information and the characteristics of the each segment (distance, azimuth to the north and pressure) of the path, it is possible to provide functional navigation guidance to the visually impaired subject. Three different visually impaired people (one partially sighted and two fully blind) and three sighted people have tested the paths. The efficiency of the navigation is analyzed in terms of distance and time using the comparison between blind and sighted people. Findings The main finding is that it is possible to guide visually impaired people some hundreds of meters just using the sensors of a smart phone under certain conditions: the visually impaired person has to understand the guidance instructions and respect some strategies (e.g. not to walk diagonally across vast spaces). Additionally it is observed that the visually impaired participants walked distances, which are not much different to the optimal values. On the other hand; because of their hesitations using their white cane to find free paths, they take in some cases 50 percent more time to arrive (for a few minutes path, this time is not critical and even more efficient than looking for a guide). One thing to highlight is that even with this hesitation, the subjects arrived to the final destination. Originality/value This paper demonstrates how an IMU coupled to a compass and a barometer from a Smart Phone employing a spoken mobility language (e.g. next corridor to the left; at the end of the stairs turn right, turn left, etc.) can guide visually impaired people inside buildings.

Evaluating Unity created teaching simulations within occupational therapy

Purpose The purpose of this paper is to describe the evaluation of an educational occupational therapy home visit simulation newly built in Unity, compared with a previously created simulation based in the Open Sim platform. The evaluation is based on students’ preferences. Design/methodology/approach A simulation was built in Unity in which the academic content was identical to the previous Open Sim-based simulation. Student groups used the simulations then completed a questionnaire. Numerical data and descriptive comments were analysed. Findings Students preferred the simulation built in Unity to the Open Sim simulation. Improvements with the Unity simulation include; reduced time to gain competence to use, ease of use and fewer negative physiological experiences. The small percentage of students experiencing motion sickness is an ongoing concern and warrants further investigation. The Unity simulation may also be useful as an academic assessment tool. Research limitations/implications Findings are limited by short time usage of the simulations in 3D virtual worlds with confined spaces and no requirement for in-world group interaction, and by some methodological limitations including the research being based within a single higher education institution, and with a profession-specific group of students. Originality/value This paper highlights student preference for using a purpose built simulation created with Unity over a simulation built in Open Sim, showing where best to spend future development time and funding. Similar comparison research is scarce.
