Big-box retailers have a customer service challenge: it's hard to find merchandise due to such large spaces and items that are moved around for a variety of reasons. This creates frustration for consumers. Takemetuit(TMTI) has a smart-device indoor real-time location system or RTLS. The platform navigates people to within 10cm in 3 dimensions of any item, 99.6% of the time. There is no other RTLS technology with this level ofaccuracy and reliability. TMTI's challenge is to reduce the installation cost. The technology exploits theproperties of acoustic wave propagation to enable a smartphone to determine its location within a controlledenvironment. Audible acoustic frequencies in the range of 200Hz to 20KHz are employed to allow theapplication to function effectively on a regular smartphone without specialized hardware. A successful proof ofconcept for the system was implemented in 2016 in a completed collaborative NSERC Engage applied researchproject with the Southern Alberta Institute of Technology's (SAIT) Centre for Innovative InformationTechnology (CIITS). The system was streamlined in a second SAIT CIITS two-year NSERC ARD2 projectthat ended in early 2020. The same team refined the tool and a proof of concept was implemented on a smart phone. Fundamental components were developed to embed the physical layer positioning engine within a user application suitable for use by a shopper. The acoustic indoor positioning system (AIPS) system is close tocommercial deployment. The goal is to move the product from technology readiness level (TRL) 8 to TRL 9, a commercial product.

大型零售商面临客户服务挑战：由于如此大的空间和物品出于多种原因而四处移动，因此很难找到商品。这给消费者带来了挫败感。 TakeMetuit（TMTI）具有智能设备室内实时位置系统或RTL。该平台在任何项目的3个维度中，将人们驶入10厘米以内，99.6％的时间。没有其他RTLS技术具有这种水平的准确性和可靠性。 TMTI的挑战是降低安装成本。该技术利用声波传播的专业人物使智能手机能够确定其在受控环境中的位置。使用200Hz至20kHz范围内的声音频率可允许触发器在没有专门硬件的情况下在常规智能手机上有效运行。该系统的成功证明是在2016年与南部艾伯塔省理工学院（SAIT）创新信息技术技术中心（CIITS）的完整合作NSERC参与中实施的。该系统在第二次SAIT CIITS两年的NSERC ARD2 Project于2020年初结束。同一团队完善了该工具，并在智能手机上实施了概念证明。 开发了基本组件将物理层定位引擎嵌入适合购物者使用的用户应用程序中。声学室内定位系统（AIPS）系统是关闭的商业部署。目的是将产品从技术准备水平（TRL）8移至商业产品TRL 9。
