Space and Proximity
As conversation groups grow in numbers the space between individuals increases to allow visual connection for all parties. This basic dimension of the space between people impacts the basic layout of furnishings and building spaces (Gallaudet University, Deaf Space).
When communicating in Sign Language, more space is needed between speaking partners to obtain a good visual of the conversation. The space should be between 3 feet and 10 feet for the conversation to be clear to each of the individuals. The space and proximity principle influences the design of a building because it means that areas need to be wide instead of narrow. For example, hallways need to be wide enough so that people can walk side-by-side when having a visual conversation.
Sensory Reach
Spatial orientation and the awareness of activities within our surroundings are essential to maintaining a sense of well-being. Deaf people “read” the activities in their surroundings that may not be immediately apparent to many hearing people through an acute sensitivity of visual and tactile cues such as the movement of shadows, vibrations, or even the reading of subtle shifts in the expression/position of others around them (Gallaudet University, Deaf Space).
Deaf individuals have an acute situational and environmental awareness, with wide peripheral vision and increased sensitivity to movements around them. Deaf people are uncomfortable when their backs are to others and/or activities, because they are somewhat "blinded" to what is going on behind them. Therefore, in accordance with DeafSpace principles, it is best if the Deaf person has greater than 180 degree vision. In classrooms, for example, a circular seating arrangement is better than the atypical layout of rows of seats. Likewise, in a work environment, cubicles or offices should be designed so that the Deaf individual faces outward from his/her desk.
Elements of Sensory Reach
From the unpublished volume of DeafSpace Design Guideline complied by Hansal Bauman and dozens of contributors, each principle have between six to twenty-three elements to take in consideration during the design process of a DeafSpace building.

Mobility and Proximity
While walking together in conversation signers will tend to maintain a wide distance for clear visual communication. The signers will also shift their gaze between the conversation and their surroundings scanning for hazards and maintaining proper direction (Gallaudet University, DeafSpace).
When on the move, people need to observe possible barriers or obstacles ahead of them as they walk, jog, drive, or bike. In the case of Deaf individuals, conversing while walking requires that they take turns keeping an eye on what is in front of them in case there is an obstacle. For example, telephone poles on sidewalks can be harmful obstacles, especially considering how narrow the sidewalks are in most cities. Conversational signers would warn their partners if they are about to walk into an obstacle. In accordance with the concept of DeafSpace, it would be necessary to ensure that obstacles or barriers are moved away from general walking paths. For example, hallways should be free of objects or steps, unless in stairways.

Light and Color
Poor lighting conditions such as glare, shadow patterns, back lighting interrupt visual communication and are major contributors to the causes of eye fatigue that can lead to a loss of concentration and even physical exhaustion. Proper electric lighting and architectural elements used to control daylight can be configured to provide a soft, diffused light 'attuned to deaf eyes.' Color can be used to contrast skin tone to highlight sign language and facilitate visual wayfinding (Gallaudet University, DeafSpace).
Color has a strong effect on everyone's vision. Considering that members of the Deaf community may experience more eyestrain than others, as their language is visual rather than verbal, it has been suggested that soft green and blue tones are the best choices as background colors. The reason is that soft green and blue tones match everyone's skin color, which will cause less eyestrain for Deaf people while conversing in Sign Language.
Light is also an important factor for the Deaf community because when the lighting is poor or too bright it may cause eyestrain or headaches. Soft, diffused lighting, similar to when the glare of the sun is blocked out, with toned down brightness. Natural, diffused lighting is better than bright, fluorescent light bulbs, for example.

Acoustics
Deaf individuals experience many different kinds and degrees of hearing levels. Many use assistive devices such as hearing aids or cochlear implants to enhance sound. No matter the level of hearing, many deaf people do sense sound in a way that can be a major distraction, especially for individuals with assistive hearing devices. Reverberation caused by sound waves reflected by hard building surfaces can be especially distracting, even painful, for individuals using assistive devices. Spaces should be designed to reduce reverberation and other sources of background noise (Gallaudet University, Deaf Space).
Acoustics take into consideration the fact that Deaf individuals may have some type of hearing assistance device or have sensitivity to vibrations in buildings. It is important for buildings to be structurally designed to offset vibrations. For example, old houses are infamous for their creaking noises, which produce vibrations that disturb Deaf individuals. Reverberation needs to be reduced in buildings, along with muting of background noises, to minimize interference with hearing devices and other sensitivity to sounds/vibrations.
