Public information kiosks are becoming more and more common. However, their user interfaces are still based on simple button interfaces, which may be implemented with physical buttons or with virtual buttons drawn on a touchscreen. We have implemented a multimodal kiosk prototype that is based on touch and speech input. This paper describes an evaluation in which 23 users compared five area sel...

This paper addresses the prediction of movement time of mouse-based cursor transfers between objects in a graphical user interface. We present the data from an experimental study aimed at obtaining an appropriate model for movement time prediction. As can be seen from the data, Fitts’ law which is widely used as a predictor for such movements fails with our data. This is not only for low values...

This study investigated the relationship between thumb muscle activity and thumb operating tasks on a smartphone touchscreen in elderly users (right hand posture). Three thumb muscles were targeted in the experiment, namely, abductor pollicis brevis, abductor pollicis longus (APL) and first dorsal interosseous (FDI). The results showed that the elderly participants developed fatigue rapidly and...

An often-heard complaint about hearing aids is that their amplification of environmental noise makes it difficult for users to focus on one particular speaker. In this paper, we present a new prototype Attentive Hearing Aid (AHA) based on ViewPointer, a wearable calibration-free eye tracker. With AHA, users need only look at the person they are listening to, to amplify that voice in their heari...

The activation point of a button is defined as the depth at which it invokes a make signal. Regular buttons are activated during the downward stroke, which occurs within the first 20 ms of a press. The remaining portion, which can be as long as 80 ms, has not been examined for button activation for reason of mechanical limitations. The paper presents a technique and empirical evidence for an ac...

In animal behavioral biology, there are several cases in which an autonomous observing/training system would be useful. 1) Observation of certain species continuously, or for documenting specific events, which happen irregularly; 2) Longterm intensive training of animals in preparation for behavioral experiments; and 3) Training and testing of animals without human interference, to eliminate po...

Many companies are using social sharing buttons to make it easier for consumers to refer a website or app to other potential consumers. Although these buttons are ubiquitous online, it remains unclear whether consumer referral propensity (i.e. the likelihood of consumers referring other consumers) varies across the channels through which consumers arrive at the website. In particular, we test w...

Providing haptic cues can generate increased levels of presence in users as they interact with tangible objects. In this paper, we present button effects delivered by air-jet displays with the aim of providing click-like sensations when virtual buttons in an AR environment are pressed. We derive the profile of the haptic output by measuring the force profile of real physical buttons. To validat...

Recently, the development of design and manufacturing system for mass customization has been growing rapidly. In the market, many companies try to provide toolkits called as ‘configurator’ which directly enables to configure the products and services by the user. These toolkits take the metaphor for converting from user preference to the numerical value. For example, the web based configurators...

Incorporating evaluation metrics with GUI development tools will help designers create consistent interfaces in the future. Complexity in design of interfaces makes efficient evaluation impossible by a single consistency checking evaluation tool. Our focus is on developing a family of evaluation tools in order to make the evaluation process less cumbersome. We have developed a dialog box typefa...
