In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. Some computer hardware devices, such as a touchscreen, can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system. Hardware interface Hardware interfaces exist in many components, such as the various buses, storage devices, other I/O devices, etc. A hardware interface is described by the mechanical, electrical, and logical signals at the interface and the protocol for sequencing them (sometimes called signaling). A standard interface, such as SCSI, decouples the design and introduction of computing hardware, such as I/O devices, from the design and introduction of other components of a computing system, thereby allowing users and manufacturers great flexibility in the implementation of computing systems. Hardware interfaces can be parallel with several electrical connections carrying parts of the data simultaneously or serial where data are sent one bit at a time. Application binary interface and Application programming interface A software interface may refer to a wide range of different types of interface at different "levels". For example, an operating system may interface with pieces of hardware. Applications or programs running on the operating system may need to interact via data streams, filters, and pipelines. In object oriented programs, objects within an application may need to interact via methods. A key principle of design is to prohibit access to all resources by default, allowing access only through well-defined entry points, i.e., interfaces. Software interfaces provide access to computer resources (such as memory, CPU, storage, etc.) of the underlying computer system; direct access (i.e.

Optimizing Java on Truffle

Ekaterina Goltsova

Java on Truffle is an early-stage implementation of a Java Virtual Machine in Java. So far its development has focused on compatibility and functionality, not addressing performance in a systematic way. This thesis presents a series of experiments on Java on Truffle performance, namely adding Class Hierarchy Analysis, improving receiver profiling at callsites of virtual and interface methods, splitting methods per-callsite, delaying the collection of profiling information, and investigating and improving System.arraycopy performance.

HapTwist: Creating Interactive Haptic Proxies in Virtual Reality Using Low-cost Twistable Artefacts

Yi-Shiun Wu

In this paper, we present a series of studies on using Rubik's Twist, a type of low-cost twistable artefact, to create haptic proxies for various hand-graspable VR objects. Our pilot studies validated the feasibility and effectiveness of Rubik's-Twist-based haptic proxies. The pilot results also revealed user challenges in the physical shape creation, motivating the development of the HapTwist toolkit. The toolkit consists of the shape-generation algorithm, the software interface for shape-construction guidance and interaction authoring, and the hardware modules for constructing interactive haptic proxies. The user studies showed that HapTwist was easy to learn and use, and it significantly improved user performance in creating interactive haptic proxies with Rubik's Twist. Furthermore, HapTwist-generated haptic proxies achieved similar VR experience as the real objects.

Object-oriented programming

Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data and code. The data is in the form of fields (often known as attributes or properties), and the code is in the form of procedures (often known as methods). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object.

Separation of concerns

In computer science, separation of concerns is a design principle for separating a computer program into distinct sections. Each section addresses a separate concern, a set of information that affects the code of a computer program. A concern can be as general as "the details of the hardware for an application", or as specific as "the name of which class to instantiate". A program that embodies SoC well is called a modular program. Modularity, and hence separation of concerns, is achieved by encapsulating information inside a section of code that has a well-defined interface.
