Questions

Q.1 Briefly define the concept of multisensory perception. What impact does the concept have on the provision of assistive technology for visually impaired and blind people?

Q.2 Draw and label a sketch of a vertical sectional view of the eye. Q.3 Discuss the role of intraocular eye pressure in eye health.

Q.4 What is the process of accommodation?

Q.5 Give illustrations of three types of visual impairment and discuss what types of safety issues people with these types of visual impairment might experience.

Q.6 Define myopia, hyperopia and astigmatism. Draw diagrams showing the effect of the use of corrective lenses for each condition.

Projects

P.1 Investigate further the concept of multisensory perception. Construct a list of the characteristics of the senses of vision, hearing, touch and smell. Construct a table showing which of these characteristics are unitary and which are complementary. You should indicate any factors which affect the classification. Consider how the sense of smell might be used in assistive technology systems for deafblind people.

P.2 Investigate further the demographics of visual impairment. Construct a table of the inter-relationships between vision, health, age, gender, and the need for assistive technology. Use this table to investigate the types of barriers people in the different categories might experience in carrying out employment, everyday living and recreational activities. Discuss how these barriers might be overcome.

P.3 Use appropriate Web and journal sources to investigate the latest developments in retinal prostheses. Construct a classification of the different research avenues being followed in this work. Give an assessment of the state of the art in each of the categories in your classification.
