项目摘要

Takemetuit (TMTI) is a Canadian company developing acoustic indoor positioning systems (IPS) for the retail industry that allow shoppers and employees to search, map and find specific products by an application on the user's cellphone or tablet. The technology exploits the known properties of acoustic wave propagation to enable a smartphone to determine its location within a controlled environment. Audible acoustic frequencies in the range of 200Hz to 20KHz are employed to allow the application to function effectively on a regular smartphone microphone without specialized hardware. A successful proof of concept for the system has been implemented in an NSERC Engage grant project in which SAIT participated with TMTI. The proposed research is focused on bringing the current state of the prototype system to the level of production prototype in which low level software routines are finalized and fitted into a hierarchical software structure to form a complete prototype user application. The project will be a critical step in TMTI's development of a leading IPS in Canada for retailers that will effectively improve employee productivity and reduce costs associated with inventory management. The IPS will also enhance shopping convenience for customers by helping them to easily find the items they seek.

Takemetuit（TMTI）是一家加拿大公司，为零售业开发声学室内定位系统（IPS），允许购物者和员工通过用户手机或平板电脑上的应用程序搜索、绘制地图和查找特定产品。该技术利用声波传播的已知特性，使智能手机能够确定其在受控环境中的位置。采用200 Hz至20 KHz范围内的可听声学频率，以允许应用程序在没有专用硬件的情况下在常规智能手机麦克风上有效地运行。一个成功的概念证明系统已实施的NSERC参与赠款项目，SAIT与TMTI参与。建议的研究重点是将原型系统的当前状态带到生产原型的水平，在生产原型中，低级别的软件例程被最终确定并适合分层软件结构，以形成完整的原型用户应用程序。该项目将是TMTI在加拿大为零售商开发领先的IPS的关键一步，该IPS将有效提高员工的生产力并降低与库存管理相关的成本。IPS还将通过帮助客户轻松找到他们想要的物品来提高购物便利性。
