Eye-gaze technology allows individuals with severe physical disabilities and complex communication needs to control a computer or other devices with eye-gaze, thereby enabling them to communicate and participate in society. To date, most research on eye-gaze controlled devices related to persons with disabilities has focused on a single diagnosis in either adults or children and has included only a few participants. This current study utilized a total population survey to identify the prevalence and perceived usability of eye-gaze technology among adults and children in Sweden. Participants were 171 eye-gaze technology users with severe physical and communication impairments, ranging between 4 and 81 years. Cerebral palsy was the most common diagnosis. Daily usage was found in 63%, while 33% had weekly, and 4% had less frequent usage. Adults, compared with children, reported using their computers more frequently (65%/38%; p < 0.01), and for the activities they needed to perform (59%/31%; p < 0.01) and were more satisfied with services, indicating that service providers should prioritize and develop more effective services for children and their parents.

Introducing advanced assistive technology such as eye gaze controlled computers can improve a person's quality of life and awaken hope for a child's future inclusion and opportunities in society. This article explores the meanings of parents' and teachers' other-oriented hope related to eye gaze technology for children with severe disabilities. A secondary analysis of six parents' and five teachers' interview transcripts was conducted in accordance with a phenomenological-hermeneutic research method. The eye gaze controlled computer creates new imaginations of a brighter future for the child, but also becomes a source for motivation and action in the present. The other-oriented hope occurs not just in the future; it is already there in the present and opens up new alternatives and possibilities to overcome the difficulties the child is encountering today. Both the present situation and the hope for the future influence each other, and both affect the motivation for using the technology. This emphasises the importance of clinicians giving people opportunities to express how they see the future and how technology could realise this hope.

Assistive technology (AT) can be used as early intervention in order to reduce activity limitations in play and communication. This longitudinal case study examines eye-gaze control technology as early intervention for a young child with high spinal cord injury without the ability to make sounds. The young child was followed by repeated measures concerning performance and communication from baseline at 9 months to 26 months, and finalized at 36 months by field observations in the home setting. The results showed eye-gaze performance and frequency of use of eye-gaze control technology increased over time. Goals set at 15 months concerning learning and using the AT; naming objects and interactions with family was successfully completed at 26 months. Communicative functions regarding obtaining objects and social interaction increased from unintentional actions to purposeful choices and interactions. At 36 months, the toddler was partly independent in eye gazing, used all activities provided, and made independent choices. In conclusion, the results show that a 9-month-old child with profound motor disabilities can benefit from eye-gaze control technology in order to gradually perform activities, socially interact with family members, and make choices.

This is a case study exploring gaze-based AT as early intervention, for a ten-month-old non-verbal child with severe physical impairments. Data was collected repeatedly over time through questionnaires, videos clips, and field observations until the child was three years old.

Objective: To establish the impact of a gaze-based assistive technology (AT) intervention on activity repertoire, autonomous use, and goal attainment in children with severe physical impairments, and to examine parents’ satisfaction with the gaze-based AT and with services related to the gaze-based AT intervention.

Methods: Non-experimental multiple case study with before, after, and follow-up design. Ten children with severe physical impairments without speaking ability (aged 1–15 years) participated in gaze-based AT intervention for 9–10 months, during which period the gaze-based AT was implemented in daily activities.

Results: Repertoire of computer activities increased for seven children. All children had sustained usage of gaze-based AT in daily activities at follow-up, all had attained goals, and parents’ satisfaction with the AT and with services was high.

Discussion: The gaze-based AT intervention was effective in guiding parents and teachers to continue supporting the children to perform activities with the AT after the intervention program.

This session focuses on the latest developments of gaze-based assistive technology (AT) and the impact of gaze-based AT interventions in the home and at school. In particular, for play, communication, assessments and early intervention. The discussion focuses on how research findings can advance future developments.

Objective: To describe and explore parents’ experiences when their children with severe physical impairments receive gaze-based assistive technology (gaze-based assistive technology (AT)) for use in daily life.

Methods: Semi-structured interviews were conducted twice, with one year in between, with parents of eight children with cerebral palsy that used gaze-based AT in their daily activities. To understand the parents’ experiences, hermeneutical interpretations were used during data analysis.

Results: The findings demonstrate that for parents, children’s gaze-based AT usage meant that children demonstrated agency, provided them with opportunities to show personality and competencies, and gave children possibilities to develop. Overall, children’s gaze-based AT provides hope for a better future for their children with severe physical impairments; a future in which the children can develop and gain influence in life.

Conclusion: Gaze-based AT provides children with new opportunities to perform activities and take initiatives to communicate, giving parents hope about the children’s future.

This article reports research findings on how gaze-based assistive technology contributed to performance of daily activities for a group of children with severe physical impairments and without speech.
