Tasks that
seem obvious for us can be a real challenge for a visually impaired person. Checking
if the water bowl of her guiding dog was empty was a time-consuming and
physically demanding job for Kathleen. As Bengo, her guiding dog can’t bark,
even when he’s hungry or thirsty, his drinking bowl was sometimes empty for some
time. This brought a feeling of guilt to Kathleen but thanks to a close
cooperation we were able to solve this problem.
During a
first creativity session a lot of different ideas and solutions flourished. So
we went to visit Kathleen in a really early stage of the creation process to
set up a list of her wishes and demands. One of the ideas we had completely fit
her expectations. This gave us the opportunity to make a working prototype on
the spot. Kathleen was really happy and relieved when we came to visit her for
the second time as our prototype was broken. The fact that she really missed it
was a sign that we were on a good track.
Our
solution is a balance system that’s being put under the drinking bin. When the
weight of the water in the bin is too low a switch is turned on. This triggers
a solar powered flashing light that immediately draws the attention a Kathleen
and impels her to fill Bengo’s water bin. To make the system as efficient as
possible we offer the possibility to adjust the contact to the right weight in
a very user-friendly way.
Perstekst
Taken die voor ons vanzelfsprekend lijken kunnen voor
slechtziende personen een hele opgave vormen. Zo had Kathleen het probleem dat
ze nooit kon inschatten wanneer de drinkbak van haar geleide hond Bengo leeg
was. Als geleide hond mag Bengo niet blaffen. Ook niet wanneer hij dorst of
honger lijdt. Waardoor Bengo soms een tijdje zonder water kwam te staan. Dit
gaf Kathleen een schuldgevoel, maar dankzij de nauwe samenwerking werd dit
probleem succesvol opgelost.
Na een eerste
creatieve brainstormsessie waaruit tal van verschillende oplossingen en ideeën
bloeiden werd al vlug een afspraak gemaakt met Kathleen om een eisen- en
wensenpakket op te stellen. Een van de bedachte prototypes kwam perfect overeen
met haar verwachtingen. Dit gaf ons de mogelijkheid om ter plaatse meteen een
functioneel prototype te maken. Toen we voor de 2e maal op bezoek
gingen was Kathleen heel opgelucht ons te zien want ons prototype had het al
een paar dagen begeven. Het gemis dat dit bij haar veroorzaakte was voor ons
het bewijs dat we op het goede spoor waren.
Onze oplossing bestaat uit een balanssysteem dat onder de
drinkbak geplaatst wordt. Wanneer het gewicht van het water in de drinkbak niet
groot genoeg meer is dan wordt een contact gemaakt waardoor een op zonne-energie
gedreven lampje gaat branden. Dit trekt onmiddellijk de aandacht van Kathleen
waardoor die onmiddellijk de drinkbak kan bijvullen. Om het systeem zo
efficiënt mogelijk te maken is het contactpunt instelbaar om op een heel
gebruiksvriendelijke manier te kunnen kiezen bij welk gewicht het lichte moet
gaan branden.
