Tesler UI Standards Addenda

Date: ' lS February 1981 To: Distribution From: Larry Tesler Subject: Proposed Addenda to the LISA Uur Interface Standards, round 2 CD NFID EfVIIAL .. Attached are proposed additions and revisions to the LISA User Interface Standard (!ill Atkinson, 24 September 1980). The January 19 proposals have been reviled according to feedback from the Ja'tluary 22 re!J(ew meeting. In addition. several new changes are proposed. Text in [brackets] explains how the change fits in to the original de>cument. Text in {braces) explains why the change is needed; often, it just lists applications that require it. 11 0K" marks changes that were provisonally accepted at the January 22 review meeting. The terminology used herein is that of the September 20 document. More descrip tfve and appropriate terminology is under active development. I request that people do not object to the changes solely on the grounds of inconsistent terminology (e.g., folders containing scroll bars) There vUl be a meeting on Tuesday, February 24 from 3-4 p.m. in the Taco Room to discuss these proposals.

For.example. uhen the cursor is over a scroll arrow (section 19), the box around the arrow could fill in black While the button was up. and the arrow itself could fill in black while the button was dovn. The Terminology Committee (a joint co11UDittee of Publications, Marketing. and Softvare.) will specify the cursor shapes as well as other user feedback. The soundness of thei·:f' choices will be verified by user tests. [delete last sentence about motion of the u:icuse with the button upJ 3.
