Color discrimination and color preferences in Chimpanzees (Pan troglodytes).

Chimpanzees (Pan troglodytes) have been known for a long time to have color vision identical to humans (Grether in J Comp Psychol 29(2):167-177, 1940b; Jacobs et al. in Vis Res 36(16):2587-2594, 1996). With this study, we wonder if chimpanzees, as humans, show preferences for some colors rather than others. During a first range of experiments, we test their ability to discriminate all the colors from our set, through easy matching-to-sample tasks. The seven chimpanzees that participate in this first test show the results we can expect from chimpanzees with normal color vision. Then, six of them are tested for preferences. This range of experiments results in the existence of consistent tendencies across all the trials and situations, as chimpanzees would mostly first choose some particular colors, and conversely choose last different colors. Although the results for color discrimination are identical for all the seven chimpanzees, preference tests demonstrate four different tendencies. This study is the first step toward broader experiments, including more chimpanzee subjects, but also different species, with the only requirement of being trained to the basic use of a touch panel interface.

Touch Panel Interface to Support Explanation of Pains by Choosing Options

This paper proposes a touch panel interface to support an explanation of pains by choosing options. Medical staffs of rehabilitation must understand pain information of patients. Patients would explain their pains with words and gestures. The explanation of pain depends on the expression of the patient. If the patient does not explain his/her pains accurately, the medical staff may not have enough treatment for the patient. The proposed interface provides patients with support to explain their pains. The users input four types of pain information: the occurring condition, the part of the body, the feeling of pain, and the degree of pain. The four types of information can be input by choosing options. The interface users can explain their pains regardless of their vocabulary. We carried out an experiment to verify the efficiency of the proposed interface. We found that the proposed interface could support users to explain their pains.

Relation between impressions of a touch panels’ coloration and operation

The relationships between the colors used in the design of touch panels and the operation of electronic devices are discussed, and experiments that investigated the effects of color in the designs of touch panel interfaces on their operation and on the impressions of users have been conducted. Subjects tried mental arithmetic tests on 12 types of screen which had different color images. The "time it took to perform the task," the "number of correct answers," the "number of incorrect answers," and the "number of timeouts" were measured and counted. After the tasks were administered, the subjects answered questionnaires about their impressions of the interfaces. The average number of correct answers was higher when using "cool-casual" than when using the other colorations. Furthermore, there was a positive correlation between the number of correct answers and a preference for the display coloration. There was a strong relationship between the coloration of the interface and the speed and accuracy of the operation. The results of the study lead us to expect that both the usability and the accuracy of operations could be improved by designing the coloration of the touch panel interface appropriately.

2P1-C05 モバイル端末を用いたロボットインターフェース

In this paper, We discussed about a controlling robot using iPhone(iPod touch). Recently, smart phones are popular that have a touch panel interface and various sensors. Such movement is the cause of IRT(Information and Robotics technology) progression. Smart control method is required for controlling robot by using such rich sensor device. Three approaches of robot control interface is presented here; First, a robot control method by iPhone application with button interface. Second, Master-slave experiment by virtual 3D model in touch device. Third, Feedback control interface using acceleration sensor of the touch device. We show the demonstration of the KHR robot and 3DCG simulations.

Application of an imaging system to a museum exhibition for developing interactive exhibitions

In the National Museum of Japanese History, 215,759 artifacts are stored and used for research and exhibitions. In museums, due to the limitation of space in the galleries, a guidance system is required to satisfy visitors' needs and to enhance their understanding of the artifacts. We introduce one exhibition using imaging technology to improve visitors' understanding of a kimono (traditional Japanese clothing) exhibition. In the imaging technology introduced, one data projector, one display with touch panel interface, and magnifiers were used as exhibition tools together with a real kimono. The validity of this exhibition method was confirmed by results from a visitors' interview survey. Second, to further develop the interactive guidance system, an augmented reality system that consisted of cooperation between the projector and a digital video camera was also examined. A white paper board in the observer's hand was used as a projection screen and also as an interface to control the images projected on the board. The basic performance of the proposed system was confirmed; however continuous development was necessary for applying the system to actual exhibitions.

Active acoustic touch interface

An active acoustic touch panel interface is described that aims to detect and localise touch interactions using a minimal amount of surface preparation and hardware. Using a single transmitter and only one or two receivers, the position of a touch can be estimated by analysing the resulting changes to the frequency response of the surface. An outline of the signal processing applied is described, along with the results of initial experiments.

Neuro-Fuzzy Control of Power-Assist Omnidirectional Wheelchair Using Human-Friendly Touch Panel

An omnidirectional power-assist wheelchair must be adaptable to needs of individual attendants. We modified our neuro-fuzzy controller to improve diagonal movements. We also developed an innovative touch panel interface providing easy real-time input and feedback. Experiments confirmed the wheelchair's adaptability to user needs.

2P1-E12 館内移動用車椅子ロボットシステムの開発 : 位置情報検出機構(医療・福祉ロボティクス・メカトロニクス)

A new type of laborsaving electric wheelchair robot system for inside building use was developed. The electric wheelchair robot system has following three functions. Those are automatic movement, position detector, and fail-safe device. Not only patient but also carers can command this electric wheelchair robot by touch panel interface, and this interface is so easy to reduce their strain while operating the robot. In those 3 functions, automatic movement was already implemented by Line-Trace control with magnetic sensor system. In this study, position detector consists of laser device, CMOS camera and pattern marker sheet was developed. Users can set pattern marker sheet at any point on line trace track line easily, and the wheelchair robot system can detect it as new check point or new station point by position detector.

Usability of Touch-Panel Interfaces for Older Adults

The usability of a touch-panel interface was compared among young, middle-aged, and older adults. In addition, a performance model of a touch panel was developed so that pointing time could be predicted with higher accuracy. Moreover, the target location to which a participant could point most quickly was determined. The pointing time with a PC mouse was longer for the older adults than for the other age groups, whereas there were no significant differences in pointing time among the three age groups when a touch-panel interface was used. Pointing to the center of a square target led to the fastest pointing time among nine target locations. Based on these results, we offer some guidelines for the design of touch-panel interfaces and show implications for users of different age groups. Actual or potential applications of this research include designing touch-panel interfaces to make them accessible for older adults and predicting movement times when users operate such devices.

Multichannel sound reinforcement systems at work in a learning environment

Many people have experienced the entertaining benefits of a surround sound system, either in their own home or in a movie theater, but another application exists for multichannel sound that has for the most part gone unused. This is the application of multichannel sound systems to the learning environment. By incorporating a 7.1 surround processor and a touch panel interface programmable control system, the main lecture hall at the University of Michigan Taubman College of Architecture and Urban Planning has been converted from an ordinary lecture hall to a working audiovisual laboratory. The multichannel sound system is used in a wide variety of experiments, including exposure to sounds to test listeners’ aural perception of the tonal characteristics of varying pitch, reverberation, speech transmission index, and sound-pressure level. The touch panel’s custom interface allows a variety of user groups to control different parts of the AV system and provides preset capability that allows for numerous system configurations.

What makes a control system usable? An operational viewpoint

This report discusses the generally accepted successes and shortcomings of the various computer and hardware-based control systems at the Los Alamos Meson Physics Facility (LAMPF) from an operator's standpoint. LAMPF currently utilizes three separate control rooms that, although critically co-dependent, use distinct operating methods. The first, the Injector Control Room, which is responsible for the operation of the three ion sources, the 750 keV transport lines and the 201.25 MHz portion of the linac, uses a predominantly hardware-based control system. The second, the LANSCE Control Room, which is responsible for the operation of the Los Alamos Neutron Scattering Center, uses a graphical touch-panel interface with single-application screens as its control system. The third, the LAMPF Central Control Room, which is responsible for the overall operation of LAMPF, primarily uses a text-oriented keyboard interface with multiple applications per screen. Though each system provides generally reliable human interfacing to the enormously complex and diverse machine known as LAMPF, the operational requirements of speed, usability, and reliability are increasingly necessitating the use of a standard control system that incorporates the positive aspects of all three control systems.

Emulating conventional operator interfaces on window-based workstations

This paper explores an approach to support the LAMPF and PSR control systems on VAX/VMS workstations using DECwindows and VI Corporation DataViews as the operator interface. The PSR control system was recently turned over to MP division and the two control-system staffs were merged into one group. One of the goals of this new group is to develop a common workstation-based operator console and interface which can be used in a single control room controlling both the linac and proton storage ring. The new console operator interface will need a high-level graphics toolkit for its implementation. During the conversion to the new consoles it will also probably be necessary to write a package to emulate the current operator interfaces at the software level. This paper describes a project to evaluate the appropriateness of VI Corporation's DataViews graphics package for use in the LAMPF control-system environment by using it to write an emulation of the LAMPF touch-panel interface to a large LAMPF control-system application program. A secondary objective of this project was to explore any productivity increases that might be realized by using an object-oriented graphics package and graphics editor.
