Positioning, stabilising, and interfacing structures and system incorporating same

A head-mounted display system, comprising:

• an interfacing structure for a display unit constructed and arranged to be in opposing relation with a user's face,
• wherein the interfacing structure comprises a substantially continuous face engaging surface adapted to contact the user's face around a periphery of the user's eyes,
• wherein the interfacing structure comprises an elastomeric material, and
• wherein the interfacing structure comprises a membrane including the substantially continuous face engaging surface, and wherein the membrane comprises the elastomeric material;
• and
• a nasal ledge comprising a support structure and a pair of elastic flaps, each of the pair of elastic flaps configured to project inwardly from the support structure towards one another so that the pair of elastic flaps form a gap therebetween adapted to receive the user's nose,
• wherein each of the pair of elastic flaps includes a face engaging surface adapted to contact a respective side of the user's nose,
• wherein each of the pair of elastic flaps is configured and arranged to contact the respective side of the user's nose and elastically bend towards the display unit so as to rest on the respective side of the user's nose without applying substantial compressive pressure on the respective side of the user's nose, and
• wherein the face engaging surface of each of the pair of elastic flaps forms a continuation with the substantially continuous face engaging surface of the membrane.

A head-mounted display system, comprising:

• an interfacing structure for a display unit constructed and arranged to be in opposing relation with a user's face,
• wherein the interfacing structure comprises a face contacting portion and a non-face contacting portion,
• wherein the interfacing structure comprises an elastomeric material,
• wherein the face contacting portion comprises a membrane including a face engaging surface adapted to contact the user's face around a periphery of the user's eyes,
• wherein the non-face contacting portion comprises a support structure and a ledge configured to project inwardly from the support structure,
• wherein the interfacing structure further comprises a foam cushion,
• wherein the membrane and the face engaging surface thereof covers the foam cushion such that the foam cushion is underneath the face engaging surface, and
• wherein the non-face contacting portion is configured and arranged to resiliently support the foam cushion and the membrane;
• and
• a nasal ledge comprising a support structure and a pair of elastic flaps, each of the pair of elastic flaps configured to project inwardly from the support structure towards one another so that the pair of elastic flaps form a gap therebetween adapted to receive the user's nose,
• wherein each of the pair of elastic flaps includes a face engaging surface adapted to contact a respective side of the user's nose, and
• wherein each of the pair of elastic flaps is configured and arranged to contact the respective side of the user's nose and elastically bend towards the display unit so as to rest on the respective side of the user's nose without applying substantial compressive pressure on the respective side of the user's nose.
