Figure 1. Etherphone system components.
Figure 2. A Cedar screen in use. The two windows in the upper left show a document preparation task, including voice annotation of this paper. The bottom window of this pair shows new voice (represented by arrowheads) being inserted in the middle of an existing voice annotation. The two windows in the lower left show a programming task that is monitoring part of the voice annotation system. The two windows in the upper right show images created with several graphical illustration packages. The window at the lower right accepts user commands, similar to a Unix shell. The bottom row of icons represent files and tools that are active but are not currently being manipulated by the user.

Figure 3. Two workstation telephone management windows. The upper Finch window provides a two-dimensional user interface to the Etherphone system. It includes an Etherphone control menu (the first line, including `Phone', `Answer', etc. buttons), a redialing area (the second line), an area for system status reports, and a conversation log (indicating a call in progress to Aquarius Theater info). The lower window shows a portion of a personal telephone directory, which is a set of speed-dialing buttons that can be created easily from an ordinary text file. The call in progress was placed by clicking on the underlined `Aquarius Theater info' entry.

Figure 4. Etherphone system icons. The two icons at the left show a closed personal telephone directory and a Finch icon at rest. The four central icons show several stages of an incoming call from Doug Wyatt (username Wyatt.pa): the three left icons of the group are animated during ringing, while the right conversation icon is used after the call has been answered. The rightmost icon shows an outgoing call to Polle Zellweger's home. Animation and visual feedback in the icons provide useful information without consuming valuable screen area.

Figure 5. Voice annotation and editing. The upper window shows voice annotations being added to a Tioga document (the voice annotation system documentation). The third line of menu buttons ("AddVoice PlayVoice ...") near the top of the window are used to manipulate voice. In the second line of text, a voice annotation appears on the word "short", indicated by the comic-strip dialog `balloon' surrounding the character. In the fifth line, a similar annotation has been opened for editing in the lower window, labelled "Sound Viewer #1". In the sound-and-silence profile in the lower window, white rectangles depict silence, while dark rectangles depict sound. The profile contains several contextual indicators to orient the user during editing. The playback cue (the gray rectangle underneath the word "score") indicates the progress of voice playback. A temporary marker in the form of a small cross has been placed in the voice section marked "Intro". The textual annotations with arrows are permanent markers that will be stored with the document.
