3G Eyephone
• Project with:
– 10 test persons
– 10 friends that guide
– Opplysningen AS as additional guide centre
• Hand out 2 pieces 3G mobile phones to each
• Study user pattern for 4 months
• Study implications for Opplysningen as a guide service

Research Questions
Based on earlier results:
• Will 3G videotelephony be perceived as "good enough"?
• Will selected friends and family be the guide?
• Will Opplysningen AS be the supplimented guide service
– (for example for confidential topics)?

Conclusions• Totally, 100 test persons in the project, 10 for 3G
• Used for:– Regain control when lost
– Find something lost
– To operate devices (mini-bank, washing machine)
– Reading text (signs, soup packet instructions)
• Though too poor quality (for certain situations), users adopt– Inadequate for:
– Viewing the environment with many details
– Reading small text
• The users feel safer with the Eye-phone
• Range of movement has expanded
• Close family feels more relaxed
