- This paper presents the process and results of a set of studies within the ABBI EU project, with the general aim to co-design wearable technology (an audio bracelet) together with visually impaired children, starting at a young age. The authors discuss user preferences related to sounds and tactile materials and present the results of a focus group with very young visually-impaired children under the age of 5, together with their parents. They find that multisensory feedback (visual, tactile/haptic, auditory) is useful and that preferences vary - also the drastic and potentially unpleasant sounds and materials may have a role. Further studies investigate the possibilities of using the ABBI wearable technology for social contexts and games. In a series of game workshops children with and without visual impairments created games with wearable technology employing very simple interactivity. The authors report the created games, and note that even with this simple interactivity it is possible to create fun, inclusive and rich socially co-located games.

How Valid Are the Rates of Down Syndrome Internationally? : Findings from the International Clearinghouse for Birth Defects Surveillance and Research

Tidskriftsartikel (refereegranskat)abstract
- Rates of Down syndrome (DS) show considerable international variation, but a systematic assessment of this variation is lacking. The goal of this study was to develop and test a method to assess the validity of DS rates in surveillance programs, as an indicator of quality of ascertainment. The proposed method compares the observed number of cases with DS (livebirths plus elective pregnancy terminations, adjusted for spontaneous fetal losses that would have occurred if the pregnancy had been allowed to continue) in each single year of maternal age, with the expected number of cases based on the best-published data on rates by year of maternal age. To test this method we used data from birth years 2000 to 2005 from 32 surveillance programs of the International Clearinghouse for Birth Defects Surveillance and Research. We computed the adjusted observed versus expected ratio (aOE) of DS birth prevalence among women 25-44 years old. The aOE ratio was close to unity in 13 programs (the 95% confidence interval included 1), above 1 in 2 programs and below 1 in 18 programs (P < 0.05). These findings suggest that DS rates internationally can be evaluated simply and systematically, and underscores how adjusting for spontaneous fetal loss is crucial and feasible. The aOE ratio can help better interpret and compare the reported rates, measure the degree of under- or over-registration, and promote quality improvement in surveillance programs that will ultimately provide better data for research, service planning, and public health programs.

Interaction gestures for a wearable device defined by visually impaired children

Konferensbidrag (refereegranskat)abstract
- This paper reports results from two workshops organized with children with visual impairments ranging from blindness to low vision. The aim of the workshops was to suggest gestures for the interaction with a small wearable audio-bracelet. Results show a preference for mechanical buttons and touch-based gestures on the device (mainly tapping and sliding), while only one tentative suggestion is made for a gesture made with the device (shaking).
