These tools allow the user's creativity to directly interact with the essential features of each video by offering spatial and temporal clues. This paper introduces the basic concept and describes prototype versions of the tools as implemented in a video handling system.

However, building a user model may be a tedious and time consuming task that will render such an interface unattractive to developers. We thus need an effective means of inferring the user model at low cost. In this paper, we describe a technique for automatically inferring a fine-grain model of a user's knowledge state based on a small number of observations. With this approach, the domain of knowledge to be evaluated is represented as a network of nodes (knowledge units—KU) and links (implications) induced from empirical user profiles. The user knowledge state is specified as a set of weights attached to the knowledge units that indicate the likelihood of mastery. These weights are updated every time a knowledge unit is reassigned a new weight (e.g., by a question-and-answer process). The updating scheme is based on the Dempster-Shafer algorithm. A User Knowledge Assessment Tool (UKAT) that employs this technique has been implemented. By way of simulations we explore an entropy-based method of choosing questions, and compare the results with a random sampling method. The experimental results show that the proposed knowledge assessment and questioning methods are useful and efficient in inferring detailed models of user-expertise, but the entropy-based method can induce a bias in some circumstances.","PeriodicalId":407219,"journal":{"name":"Proceedings of the INTERACT '93 and CHI '93 Conference on Human Factors in Computing Systems","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132734018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An interface agent records the steps of the procedure in a symbolic form, using machine learning techniques, tracking relationships between graphical objects and dependencies among the interface operations. The agent generalizes a program that can then be used on “analogous” examples. The generalization heuristics set it apart from conventional “macros” that can only repeat an exact sequence of steps. The system represents user-defined operations using pictorial “storyboards” of examples.

The lessons learned can be grouped into two categories: 1) Process, and 2) Architecture of the Interface. Our goal in developing a tool for choreography has been to provide computer-based creative design support for the conception and development of dance. The evolution was driven by feedback from the choreographers and users who were members of the development team, combined with our knowledge of current thinking on design and composition. Although the interface evolved in a relatively unconstrained way, the resulting system has many of the features that theoretical discussion in human interface design has projected necessary. The Life Forms interface has evolved incrementally with one major discontinuity where adoption of a new compositional primitive required a completely new version.","PeriodicalId":407219,"journal":{"name":"Proceedings of the INTERACT '93 and CHI '93 Conference on Human Factors in Computing Systems","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132220742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss some of the relative merits of this mode of viewing as compared to head mounted stereo displays. In addition, we report the experimental investigation of the following variables: 1) whether or not the perspective view is coupled to the actual viewpoint of the observer, 2) whether stereopsis is employed. Experiment 1 involved the subjective comparison of pairs of viewing conditions and the results suggest that head coupling may be more important than stereo in yielding a strong impression of three dimensionality. Experiment 2 involved subjects tracing a path from a leaf of a 3D tree to the correct root (there were two trees intermeshed). The error rates ranged from 22% in the pictorial display, to 1.3% in the head coupled stereo display. The error rates for stereo alone and head coupling alone were 14.7% and 3.2% respectively. We conclude that head coupling is probably more important than stereo in 3D visualization and that head coupling and stereo combined provide an important enhancement to monitor based computer graphics.","PeriodicalId":407219,"journal":{"name":"Proceedings of the INTERACT '93 and CHI '93 Conference on Human Factors in Computing Systems","volume":"13 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132934136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each newly typed in letter filters suggestions that contain it with a priority for uppercase letters. Evahtation of TYP, MTYPs predecessor, showed that higher cognitive functions are more important for effectiveness of use than a mere reduction of the number of keystrokes. This was used as feedback to development and has led to automatical acceptance of unique suggestions accompanied by a beep to limit eye screen contact and to improvements of the filter as well. These functions can be toggled on and off and it is interesting to experience the final system using a data base that simulates a counter. None of these possibilities has been implemented. In real life people often prefer to memorize abbreviations or numbers to prevent eye screen contact or a paper search and they may well prefer them over Filter@ Suggestions. It is not clear if further research is indicated as this would be very time consuming and TYP is hardly ever used. A floppy disc for DOS machines with MTYP and TYP’s prototype on it is available.

But 700 names seems about the upper limit for effective Filtered Selections to be possible. TYP was designed as a “language sensitive editor” for programming languages and can be demonstrated as well.

Novice users enter text using “hunt-and-peck,” experts use touch-typing. Although it takes time to learn touch-typing, there is a large payoff in faster operation. In contrast to keyboarda, pen-based computers have only a novice mode for text entry in which users print text to a character recognize. An electronic pen (or stylus) would be more attractive as an input device if it supported expert users with some analogue of touch-typing. We present the design and preliminary analysis of an approach to stylus touch-typing using an alphabet of uni-strokes, which are letters specially designed to be used with a stylus. Unistrokes have the following advantages over ordinary printing they are faster to write, less prone to recognition error, and can be entered in an “eyes-free” manner that requires very little screen real estate.","PeriodicalId":407219,"journal":{"name":"Proceedings of the INTERACT '93 and CHI '93 Conference on Human Factors in Computing Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114237003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
