Participant #2 (male)

Reading

uses portrait format to read text arranged in columns
uses landscape format to read text/pictures not arranged in columns [picture: participant2 (1)]
option to show temporarily which line is being read by the user (but it should be as minimalistic as possible)
mentioned that he would like to have a slightly longer device to read text which is not arranged in columns

uses finger to click on a word -> cursor appears -> drags cursor to the end of the text to be highlighted
OR: uses stylus to click on first word of text to be highlighted -> drags stylus to the last word of the highlighted text part [picture: participant2 (2)]

in the same way as highlighting
uses underlining when he reads paper for the first time (for the second time reading he uses highlighting to mark important words of the underlined text)

highlights/underlines text part to be annotated -> double clicks on this part -> comment box appears
makes annotations with a keyboard
comment box should be movable but default position should be outside of the text area
rotates display by 90° to have more space for adding annotations [picture: participant2 (3)]
if comments are not edited they should be minimized (a small icon could indicate that there is a comment) [picture: participant2 (5)]

clicks on a button to start search mode -> types word for search by using a keyboard -> search process starts
search results are arranged in a list on the display: each entry shows page number and title of the paragraph
user opens corresponding book page number -> uses device to find search result within the page (search results are highlighted)
would like to have a symbol/icon (no HALO) in case there are results on the current page which are not within the display's screen
user thinks a halo may appear too distracting if too many search results exist on the same page
would also like to see the number of search results of the current page

button to show a list of annotations -> each entry shows page number and title of the paragraph
open corresponding page number
uses display in landscape format (just one half of the device covers the page) to find annotations
while moving the display on the paper, annotations are shown -> comment box is shown on the display's part which does not cover the text
shows only one comment completely at the same time (other comments are shown as an icon) - as default the comment which is closest to the middle of the device should be shown completely
to see other comments completely the display has to be moved
an icon (no halo technique) indicates whether there are more annotations on the same page

to compare annotations of two persons [picture: participant2 (9-11)]
there should be a "union function" to see both the annotations of person 1 and person 2
there should be an "intersection function" to see highlighting from person 1 and person 2 which appear at the same spot
stacking two displays on top of each other (one display being rotated by 90°)
-> highlighting/underlining from both displays/users are shown within the overlapping area
-> comments are shown within the non overlapping area of the displays (comments from user #1 are shown in the non overlapping part of device #1) [picture: participant2 (13)]

lifts device above a picture on the paper -> 3D image comes up -> use the display to inspect the 3D image
