Some while ago I was in a course meeting and during the conversation I said " I've learnt some really important things whilst marking student exams ". To say there was a stunned silence would perhaps exaggerate, but certainly a few of my colleagues looked at me rather oddly. In fact I often find that when I set open-ended exam questions I find pertinent issues raised in the answers that weren't part of my sample solution. However, there was a particular incident which was in my mind. Some years ago I was teaching part of a course on visual-ization and virtual reality. One of the questions I asked was about factors that lead to a sense of 'engagement' in virtual reality and the question was set in the context of flight simulators and games. I'd discussed a wide range of issues in class: interactivity, realism, etc., but, when I marked the question all the best student answers started with a factor that I had never discussed in my class-indeed never heard of before-sub-seat woofers. After a moments thought I worked out what these were. In certain arcade games large bass speakers are placed under the seats to produce low frequency vibrations-a form of haptic as well as aural feedback. These students had far more practical experience than me: they spent large amounts of their lives in desktop and arcade VR games ... they were domain experts. A few weeks ago I was teaching our Masters students in an intensive week on HCI. One morning I talked to them about modelling state and gave them a group exercise to model the state of a four-function calculator. I knew from past experience that students find this more difficult than it at first sounds, but this time was worse than usual and no group made significant progress. I'm not sure what was different from previous years-perhaps a slightly different mix of students, perhaps I explained it slightly differently. As we came back together I talked through potential solutions but in particular was at pains to discuss three things. First, I emphasized that this was an area that I believed was important but I knew was conceptually difficult. Second , I pointed out (as was already in my printed materials) the places where I have made mistakes in this in the past and how to detect these. Third, I admitted that I had clearly …

In the Information Age content is a valuable commodity. Yet, most organizations fail at successfully controlling their own information. Effective content management (CM), while alone not a panacea, can alleviate the pains of information overload. In Content Management for Dynamic Web Delivery, JoAnn Hackos presents a hands-on, step-by-step approach for planning, installing, and leveraging a content management system (CMS).

out on the same 11 Hungarian Simmental fattening bulls by Falco 100 (Pie Medical) equipment (I.: age: 357±23.47 days, live weight: 475.55±51.40 kg; II.: age: 418±23.47 days, live weight: 555.10±54.11 kg) on two occasions. Animals were kept in small groups, on deep litter, and fed on silage and concentrate. LMA and P8 were measured on the scans, between the 12 th and 13 th ribs by manual outlining. Results for the investigated traits during the examinations were as follows: P8: I.: 0.373±0.154 cm, II.: 0.624±0.161 cm; LMA: I.: 65.72±5.89 cm 2 , II.: 71.74±8.94 cm 2 . During the fattening period, P8 increased significantly (I-II.: t=3.73, P<0.001). A significant positive correlation was calculated between results of measurements I. and II. in the case of LMA (r=0.71, P<0.05). Results imply the possibility of selling bulls with smaller LMA earlier, at lower body weight. Application of ultrasonic measurements in fattening technology could generate a more quality-related pricing system.

A question people ask me every so often is what are the benefits of becoming a SIGCHI/ACM Chapter. The answer to that always is, as most things in HCI, it depends. Local SIGCHI Chapters are very diverse in their consitituency, goals and activities and may value different aspects of being associated with SIGCHI and ACM (for more on Chapters' diversity see [Anderson, R. 98]). However, by becoming a chartered SIGCHI/ACM chapter there are many resources that become available to the chapter and that they can benefit from. At the Local SIGs workshop at CHI 2002 it became clear that many of the chapters are not aware of these resources. The goal of this column is to list and briefly describe these resources.
人们经常问我的一个问题是，成为SIGCHI/ACM分会的好处是什么。这个问题的答案是，和HCI中的大多数事情一样，要视情况而定。当地的SIGCHI分会在其选区、目标和活动方面非常多样化，并且可能重视与SIGCHI和ACM相关的不同方面(有关分会多样性的更多信息，请参阅[Anderson, R. 98])。然而，通过成为特许SIGCHI/ACM分会，该分会可以获得许多资源，他们可以从中受益。在CHI 2002的地方sig研讨会上，很明显许多分会不知道这些资源。本专栏的目的是列出并简要描述这些资源。

November/December 2002 7 In Crossing the Chasm, Geoffrey Moore discusses the differing needs of early adopters of new technology and the majority adopters that follow (see figure). He describes this conceptual gulf as the chasm that needs to be bridged if a technically innovative product is going to be successful in the mass market. Don Norman picks up this theme in The Invisible Computer, arguing that the chasm is largely a matter of usability (although he avoids that particular word). Both authors use numerous examples from the 1980's and 90's, but for more recent examples, we need look no further than the products serving as the building blocks of the mobile internet.
