Human machine interface

Human machine interfaces vary widely, from control panels for nuclear power plants to the screen and input buttons on a cell phone. Designing such interfaces is a challenge, and requires a great deal of work to make the interface functional, accessible, pleasant to use, and logical.

Methodologies[ edit ] A number of diverse methodologies outlining techniques for human—computer interaction design have emerged since the rise of the field in the s.

Most design methodologies stem from a model for how users, designers, and technical systems interact. Modern models tend to focus on a constant feedback and conversation between users, designers, and engineers and push Human machine interface technical systems to be wrapped around the types of experiences users want to have, rather than wrapping user experience around a completed system.

PC-Based Operator Interface: Power Through Simplicity

Activity theory provides a framework to reason about actions in these contexts, analytical tools with the format of checklists of items that researchers should consider, and informs design of interactions from an activity-centric perspective.

Users, designers and technical practitioners work together to articulate the needs and limitations of the user and create a system that addresses these elements.

Often, user-centered design projects are informed by ethnographic studies of the environments in which users will be interacting with the system. This practice is similar to participatory designwhich emphasizes the possibility for end-users to contribute actively through shared design sessions and workshops.

Principles of user interface design: VSD uses an iterative design process that involves three types of investigations: Conceptual investigations aim at understanding and articulating the various stakeholders of the technology, as well as their values and any values conflicts that might arise for these stakeholders through the use of the technology.

Technical investigations can involve either analysis of how people use related technologies, or the design of systems to support values identified in the conceptual and empirical investigations.

Before a display is designed, the task that the display is intended to support must be defined e. A user or operator must be able to process whatever information that a system generates and displays; therefore, the information must be displayed according to principles in a manner that will support perception, situation awareness, and understanding.

Thirteen principles of display design[ edit ] Christopher Wickens et al. A reduction in errors, a reduction in required training time, an increase in efficiency, and an increase in user satisfaction are a few of the many potential benefits that can be achieved through utilization of these principles.

Certain principles may not be applicable to different displays or situations. Some principles may seem to be conflicting, and there is no simple solution to say that one principle is more important than another.

The principles may be tailored to a specific design or situation. Striking a functional balance among the principles is critical for an effective design.

Make displays legible or audible. If the characters or objects being displayed cannot be discernible, then the operator cannot effectively make use of them. Avoid absolute judgment limits. Do not ask the user to determine the level of a variable on the basis of a single sensory variable e.

These sensory variables can contain many possible levels. If a signal is presented more than once, it is more likely that it will be understood correctly.

Human machine interface

This can be done by presenting the signal in alternative physical forms e. A traffic light is a good example of redundancy, as colour and position are redundant.

Signals that appear to be similar will likely be confused. The ratio of similar features to different features causes signals to be similar. For example, AB9 is more similar to AB8 than 92 is to Unnecessarily similar features should be removed and dissimilar features should be highlighted.

Mental model principles[ edit ] 6. Principle of pictorial realism. A display should look like the variable that it represents e. If there are multiple elements, they can be configured in a manner that looks like it would in the represented environment. Principle of the moving part.

For example, the moving element on an altimeter should move upward with increasing altitude. Principles based on attention[ edit ] 8. Minimizing information access cost or interaction cost. A display design should minimize this cost by allowing for frequently accessed sources to be located at the nearest possible position.

However, adequate legibility should not be sacrificed to reduce this cost. Divided attention between two information sources may be necessary for the completion of one task.

These sources must be mentally integrated and are defined to have close mental proximity.

Information access costs should be low, which can be achieved in many ways e.Mar 27,  · SpaceX and Tesla CEO Elon Musk is backing a brain-computer interface venture called Neuralink, according to The Wall Street Journal.
