Bionic eye module 3

Teacher activity

Direct students to webpage where they can complete this webquest: Exploring the Role of Resolution in Image Identification.

Student activity

Flipped classroom: Students watch video part 1 and 2.

Students complete worksheet or online questions at home prior to class.

Resources required

• Videos:
  • Visual perception: part 1
  • Visual perception: part 2
• Student-Worksheets / 01-Questions-PART-1-2.docx

Teacher activity

Lead activity of ‘Predicting what the image is’ using the webquest.

Lead class in discussion of the role of resolution in image perception using supplied.

Student activity

Students are presented with images, which are gradually revealed with an increasing grid of pixels (2x2, 3x3, 4x4 etc.). Students predict what the image is and note the resolution.

Students working in pairs play a game where a student is required to guess a symbol and image that their partner has chosen using the koalastothemax application. This application allows them to create an image which is initially restricted to a low resolution which gradually increases.

Students swap roles and repeat.

Students reflect on their methods at solving the puzzle.

The class then pools their data and analyse how they identified the symbols and images (i.e. identify edges, shapes, light/dark) and trends in the class data (i.e. more pixels allows for better distinction).

Their findings are then related to human vision.

Resources required

• Video: Visual perception: part 3
• Blog post (webquest): Exploring the Role of Resolution in Image Identification

Teacher activity

Ask students to watch videos.

Student activity

Students watch videos and answer questions.

Resources required

• Visual perception: part 4
• Student-Worksheets / 02-Questions-PART-4-Moving-FOV.docx

Teacher activity

Lead activity of ‘Predicting what the image is’ with moving view.

Student activity

Students are presented with an image that is covered by a sheet of paper that creates a “moving field of view”.

Students are encouraged to move the field of view over the pictures and see if they can identify the images hidden by the moving field of view cover.

Students reflect on their methods at solving the puzzle.

Students pool their data.

Students discuss as a class methods to solve the puzzle and analyse trends.

Students consider how this activity may reveal considerations for human vision.
