Abstract The excitation of mechanoreceptors in the finger with different frequencies and intensities generates a tactile impression. For the experience of a complete surface many distributed sources are needed in the tactile display. For these local stimulations of the finger several piezoelectric bending actuators will be arranged in an array perpendicular to the skin. The challenge in the system design is to transfer high dynamic shear forces to the skin at required frequencies together with a compact display design. In order to estimate the dynamic behavior of the bending actuators a transfer matrix method model based on the Timoshenko beam theory is derived. Beside the outer geometric values, the layered structure of the actuator is included in the model. In addition the influence of the load on the actuator’s tip in lateral and in normal direction as well as on the rotational degree of freedom is taken into account. Using the analytical approach, a parametric study is carried out to find an optimized actuator design for the display. For the validation, the modeled beam is compared with experimental data.

Technological advances have signi-ficantly altered the nature of the man-machine inter-face. Notable changes include: 1) a redefinition of the role of the human from that of a manual operator to a monitor/manager of complex systems; and 2) the availability of large amounts of data, presented or updated at rapid rates. As a result of such changes, the human operator must monitor, integrate, evaluate, and utilize continually changing information from a large number of spatially separated displays. Such demands require complex scanning patterns among numerous displays, and maintaining large amounts of information in working memory. These requirements and demands often overload the human's limited processing capabilities, and lead to degraded performance and increased probability of error. One possible solution to this propagation of displays and consequent information overload is to make more efficient use of human visual capabilities by offloading some types of information from foveal vision to peripheral vision. If appropriate types of information are presented to each aspect of vision (foveal and peripheral), then the human operator's bandwidth of information intake may be usefully increased. However, significant issues must be addressed before attempts are made to design peripheral displays. Such issues may be grouped into three categories: 1) determine the characteristics of peripheral vision relevant to display design (e.g., luminance sensitivity, contrast sensitivity, and acuity); 2) determine the characteristics of peripheral information processing (e.g., the costs and benefits of covert orienting of attention, the effects of foveal load on peripheral processing and vice-versa, and events in peripheral vision that cause a saccade); and 3) determine what types of information structure provide useful information in peripheral vision, which would indicate what types of information should be displayed in peripheral vision. The answers to these issues will provide data that may help determine whether it is feasible to display useable information to both foveal and peripheral vision, and provide guidelines for the design of peripheral displays. The purpose of this symposium is to address theoretical and applied issues of peripheral vision. The description and evaluation of the properties and characteristics of peripheral vision will serve as fundamental knowledge in determining the feasibility and design of peripheral displays. The symposium will be empirical in nature, with the participants presenting experimental data relevant to the above issues.

Models of visual attention allocation suggest that monitoring is driven primarily by proximal cues like bandwidth and value. However, these cues might not always be predictive of the meaningful events an operator is asked to monitor. The aim of the current study is to extend visual sampling models by studying whether sampling can be influenced by more distal cues, like detecting patterns in the monitored signal, when proximal cues, like bandwidth, are not predictive of the meaningful events the operator is asked to monitor. Ten participants completed a task based on Senders' (1964) experiment where operators were asked to monitor a series of four gauges to detect when the gauges traveled into the alarm region. The performance results suggest that participants could successfully adapt to the temporal sequence. However, participants did not show explicit awareness of the sequence, indicating that this type of learning could, in some cases, be implicit. Implications for display design and training are discussed.

We conducted an extensive literature survey designed to produce a document that would analyze and summarize the role of temporal factors in display design. The survey revealed that there were no data available on several questions crucial to problems in human engineering. We suggest some lines of future research and possible changes in the Military Standard.

The historical perspective allows us to take a fresh look at a complex and contradictory period in the development of museum affairs in the USSR, which entered into historiography under the name of Khrushchev’s ‘thaw’. Using archival sources that are part of the Ministry of Culture of the Byelorussian SSR record, published statistical data, as well as periodicals, the article attempts to show the growth of the museum network in the BSSR and trace the process of its profile differentiation and museum branch development during this period. Using the specified source base, an analysis of state policy and public initiatives in the field of museum work was carried out. The public discussion of the early 1960s on the role of an artist in the process of museum display design is considered. While listing and analysing museum innovations during the ‘thaw’, the author pays special attention to the legalization of the activities of Belarusian private collectors. The emergence of museum architecture as a material embodiment of socio-cultural ideas about the museum is considered separately. The transformation of Belarusian museums into a subject of international relations in 1953–1968 is presented as an important new trend in their development. Appreciating the positive changes in the life of museums during the ‘thaw’ period, the author points out that it was in those years that the subordination of all activities of Belarusian museums to the tasks of glorifying Soviet society at the expense of other historical periods was finally established at the normative level. All areas of museum activities were filled with ideological content, which reflected the general cultural policy, invariably pursued by the party leadership. The article significantly expands the museological interpretation of the ‘thaw’ era and its role in the expansion, democratization, and professionalization of museum activities.
