What Game Designers Do That Interface Designer Don’t

Posted on 07:29 by Unknown
At many occasions stakeholders ask designers to design experiences that are simple yet immersive and engaging for commercial Web applications. They leave it completely to the designers to think of ideas to achieve such designs. But, commercial Web application designers are always busy designing applications that are a function of


(Over simplification of Web application design)

They make sure all the business rules are incorporated, the right system response is in place, the right set and amount of information is presented so the right decisions are taken and so on and so forth. I would also go ahead saying that there is nothing grossly wrong with that approach. And while the results are not always great designs, they are not bad either.

But there are traits of game designs that an enterprise application designer can experiment with and design experiences that are memorable and desirable for people who use them. Theoretically, game design is not all that different and designers from other fields are perfectly capable of doing much of what game designers do.



[A gross oversimplification of game design (Stephen Anderson’s way)]

Instant Gratification vs. Slow Response Time
In most commercial software interfaces response time management is completely overlooked. The rule is “faster is always better,” and Google has almost mastered it. Search results displayed are shown with how many milliseconds it took for Google to process the results. However, game designers don’t think likewise and they defy the concept of instant gratification by making a good use of response time. It is like one driving to a hill station on a vacation with friends and family where en-route experiences are equally important as reaching the destination is. Slow response time also allows users to think of their next move.

Closure to Completion Effect
Gamers become more aggressive, thrilled, and impatient when they come very close to completion of a level, task, or an activity in a game. But game designers design these activities to be highly unpredictable and vulnerable, to take the gamers' excitement to the peak (for example, a game of Jigsaw Puzzle or Sudoku at the verge of completion). Similarly, Web application designers can start thinking of ideas to make the last piece of a task or an activity more engaging and exciting.

Learn To Become More Efficient In Future
Gamers become more efficient as they play and eventually become experts at it. Game designers leave cues that gamers use as tricks and keys to reach the expert level. The vast majority of software user interfaces have no consideration for how users can be taught by experience with the system to improve their performance. It is about finding those hidden patterns in the way people interact and manipulate the system. It is an applied learning that a user gains and reuses in different conditions to get faster results.

Short-term Memory Management
People love gaming because it challenges their reflexes, thinking, intuition, and dedication as they make progress on higher levels with increased amount of complexity. Short-term memory management is a great tool for game designers to increase or reduced the complexity of the game. Interface designers are trained not to rely on user’s short-term memory (for example, showing a piece of information and expecting the user to remember it to reenter the same somewhere else in the system).

However, game designers use it quite often in forms of locations, maps, symbols, and passwords which the gamers need to remember to clear a level or to reach a place. For example, arcade games use word codes that are displayed when the level is completed. These codes are supposed to be remembered by the player to reenter to reach that level directly from beginning else he or she will have to pass through all the previous levels to get there. Similarly, the famous AngryBird game shows the cage structure once to the player and leaves it to the player’s imagination to strike in the right area.

Building Mystery
Game designers carefully design interactions that in a way expand the player's mind and force him or her to think what’s happening. It is the mild confusion created with just enough context to consume the player’s cognition in subtle and compelling ways.

Enterprise Web application designers think of making interaction highly intuitive and transparent at all times. They think of giving surprises by making the application learn users patterns and start intelligently predicting their next move and automate it.

Experience Sense of Touch Through Haptics

Posted on 07:49 by Unknown
Human Computer Interaction (HCI) is considered to be the intersection of computer science, cognitive science, design and several other fields of study, and is a multidisciplinary field centered on people’s interactions with computers in various respects. Practitioners and researchers endeavor to understand people’s behaviors and actions in order to make computers more usable and receptive to people’s needs. People interact with machines using their physical senses including sight, hearing, taste, smell and touch. Wikipedia notes, “Senses are the physiological capacities within organisms that provide inputs for perception” [1]

The importance of touch in HCI
One way of interacting with a device is by using the sense of touch. “The touching is not limited to feeling, but it allows interactivity in real-time with virtual objects” [1]. In HCI, Haptics is a field that allows people to interact with computers. A haptic device gives people a sense of touch with computer generated environments, so when virtual objects are touched, they seem real and tangible [2]. Haptic devices are capable of measuring bulk or reactive forces that are applied by the user; it should not be confused with touch or tactile sensors that measure the pressure or force exerted by the user to the interface.

“Haptic technology, or haptics, can be defined as feedback technology that takes advantage of a user's sense of touch by applying forces, vibrations, and/or motions to the user” [1]. Haptics are implemented through different types of interactions. These interactions can be categorized into the different types of touch sensations a user can receive—force feedback, tactile feedback, and proprioception (or kinesthesia) [3]. For instance, you can change a conventional mouse into a haptic mouse by adding force feedback capability, or, in other words, a haptic mouse reacts to responses for users to make a decision.



Examples of where it is used and who benefits from haptic device
In recent years we have seen how the sense of touch has become an integral part of how we experience things, both physically and emotionally [2]. Haptic devices can be used in different applications including computers, video games, mobile consumer technologies, research, medicine, and robotics.

Most of us are familiar in using touch screen technology on cell phones; a person can interact with electronic visual display using the sense of touch. It is said to be a haptic touch screen when it provides users with true tactile feedback that supports a multitude of touch and gesture effects [4].

Haptic devices provide greater potential for people who are visually challenged. Haptic technology can assist a blind person in making right decisions while interacting with technology using the feedback provided to them. A recent study conducted at “VI Fit” [5] provides evidence for how a haptic device can benefit blind users.



Product Designers can benefit from free form modeling on products. Three-dimensional detailed shapes can be formed for manufacturing if input devices that give touch feedback relating to the "surface" they are modeling allowing faster and more natural workflow than with traditional methods [5]. These technologies could help designers creating video games with rich rendered Three-Dimensional environments that can be hard to navigate on a two-dimensional screen.

An experienced designer can create interfaces through which the end user can feel the product before purchasing the product. Designers can provide a greater experience for end user allowing them to feel the product with their own hands, for example, when an end user wants to buy a luxury watch such as Breguet. Haptics is an emerging field in HCI and many researchers around the globe are working on providing a physical experience for virtual objects.
