Disability and functional restriction:
He is visually impaired, which leads to a reduction in his vision. Therefore, because of his disability information must be presented enlarged and in high-contrast for better visual perception.
Training and job:
He is a trained physiotherapist and has been self-employed for several years.
Workplace and duties (actual status):
He recives patients in his practice and carries out applications there (figure 1). His visual impairment plays hardly any part in the treatment of patients. In recent years there is ever increasing administrative work as part of his duties. He must e.g. document the treatment course, organise appointments or write accounts for the patients and health insurances. Due to his disabilities, in these activities he is very restricted in his use of the current card index box with patient data and the diary (figure 2).
Workplace and duties (desired status):
For the administrative work the workplace was equipped with a PC
, a 19 inch TFT monitor, a camera reading system (monitor reading equipment) and a black keyboard with white large letters (high contrast) (figure 3). The TFT monitor is flicker-free and with increasing resolution (less horizontal scrolling), enables improved and high-contrast representation. Because of the reduced visual or reading distance the TFT monitor is fixed to the worktable with a swivel arm. With the help of the monitor swivel arm he can position the monitor in the best field of vision so that he has no unphysiological posture. In addition enlarging software with voice output was installed so that he can view the enlarged content of the monitor or it can be reproduced as sound via the sound card and loudspeaker. The inbuilt camera reading system is used to enlarge documents in paper format (letters, brochures, transferrals, etc.
). The content can also be enlarged and presented on the 19 inch TFT monitor.
With the additional use of the usual practice software together with the enlarging software, he can also work on the appointment planning and patient data on the monitor (figure 4). He is thus in a position to complete the administrative activities which arise without outside help.
Assistive devices used:
