4. 4 © NOKIA 2005 Virpi Roto Web pages on small devices Keyhole view problems: Hard to know what is on this page Hard to find the target content Wide texts unreadable on small screens

5. 5 © NOKIA 2005 Virpi Roto Zoom out? Miniature page: +Better understanding on whats there -Text too small to read when rows fit the screen width -Zooming either requires a dedicated key or a mode -In optimal case, you should be able to zoom & scroll at the same time, which is hard on a limited device

7. 7 © NOKIA 2005 Virpi Roto Narrow layout? Narrow layout: De facto Web viewing method 2005 on small screens +Wide texts readable -Wide images squeezed to tiny ones, impossible to interpret -Data tables ruined -Hard to know where the needed content is -Huge scrolling effort -Top content looks the same -> Déjà vu
