This research opens up for consideration the topic of a generalized simulation Applications Programming Interface. Discussion evolves around representation of one phenomenon essential to such an Interface, which is the widely used Line-of-Sight methodology. The research describes an initial set of line of sight (LOS) attributes necessary for a generalized Applications Programming Interface. Det...

With the advance of electronics and its ever growing miniaturization, embedded systems are more prominent than ever. They have long made their way from industrial applications into the consumer market, being contained in anything from cellular phones to automobiles. Their power has grown substantially, too. Today’s embedded systems easily outperform a desktop PC twenty years ago. However, their...

The purpose of the PAPI project is to specify a standard application programming interface (API) for accessing hardware performance counters available on most modern microprocessors. These counters exist as a small set of registers that count events, which are occurrences of specific signals related to the processor’s function. Monitoring these events facilitates correlation between the structu...

Open Mathematical Engine Interface (OMEI) aims to establish a uniform application programming interface specification (API) for heterogeneous mathematical computation systems. OMEI can play an essential role in making mathematical engines easily accessible by front-ends, tools, and servers. The interface enables the development of individual applications that can serve different engines. The mo...

Command interfaces to current interactive systems often appear inflexible and unfriendly to casual and expert users alike.’ We are constructing an interface that will behave more cooperatively (by correcting spelling and grammatical errors, asking the user to resolve ambiguities in subparts of commands, etc.). Given that present-day interfaces often absorb a major portion of implementation effo...

Members of a development team, often from diverse backgrounds, bring a different perspective on how to design and produce a user interface for a computer system. However, these experts are coming to agree that a good interface is crucial to the success of the system, because to the user, the interface is the system. This paper discusses my experiences as a member of a development team and provi...

The musicbox is a tangible interface supporting remote awareness through the mediums of music and light. The musicbox is linked over the Internet to the music and light levels surrounding a remote piano. The system communicates live music and a sense of physical movement through a luminous physical interface, while also providing browsable access to music previously played by the device.

This paper presents a model for more interactive interface agents. Using learning interface agents is one strategy for designing recommender systems. The more interactive style of agents presented in this paper aims to increase the trust and understanding between the user and the agent, by allowing the agent to solicit further input from the user under certain conditions. We illustrate our desi...

Adaptive graphical user interfaces have the potential to improve the user’s experience by personalizing the interface to better suit his or her needs. However, evaluations have yielded conflicting results: some studies show that adaptive menus and toolbars are faster or preferred in comparison to static counterparts [6,8], while others show the opposite [3,10,11]. We propose an evaluation appro...

Computer graphics is vital for the depiction of life-like agents for computer interfaces and visual entertainment systems. This paper develops a realistic graphical model of the human face capable of synthesizing facial expressions in natural conversation scenarios. In particular, we propose a facial muscle model that includes oral musculature for controlling mouth shapes during speech producti...
