Explanation

Let us judge an invented helper called the Flash Bell. A lamp flashes and a wristband buzzes when someone presses the doorbell, for a person who cannot hear it. It is only an idea, so nobody needs to buy anything. Use the seven questions and write yes, partly or no, with a short reason. Then count the ‘yes’ answers to get a score out of seven. A second scenario: a person with low vision wants to read books. What would you design? Perhaps a lamp-shaped reader that reads a page aloud as you hold it under it. Judge that idea with the same seven questions. Finally, think about change: how might the Flash Bell change Adel’s day? He does not need to ask anyone if the postman has come. He is more independent, and a visitor can call without waiting a long time.

Worked examples
Flash Bell4 out of 7fix the help sheet
Score of the Flash Bell: four ‘yes’, two ‘partly’, one ‘no’. So it scores 4 out of 7. The team now knows what to fix first: the help sheet.

Malak draws a reading lamp for a person with low vision. A page placed underneath is read aloud. She asks: is it usable? A grown-up helps test one button, and the answer is ‘yes’.
before: waitingafter: the lamp tells him
Before the Flash Bell Adel waited at the door for a visit. Afterwards he works at his desk and the lamp tells him when someone arrives. His day is calmer and he is more independent.
Class activity

Judge a new idea. Invent a helper for a person who cannot hear the school bell, or draw your own. Copy the seven-question table and fill it in with yes, partly or no and one reason each. Count the ‘yes’ answers and write your score out of 7. What should you improve first?
