【开源获奖案例】隔空手势识别测试系统

                ——来自迪文开发者论坛

本期为大家推送迪文开发者论坛获奖开源案例——隔空手势识别测试系统,工程师采用7英寸COF智能屏,通过T5L OS核与 PAJ7620U2手势识别传感器进行数据交互,不需要使用任何按键,只需将手贴近传感器即可进入菜单系统控制屏幕,实现上、下、左、右、贴近、远离、左旋转、右旋转、挥手9种手势效果。不一样的屏幕交互体验,推荐大家前来观看!

T5L OS核与PAJ7620U2手势识别传感器进行数据交互,检测当前的手势,判断当前显示的图片和翻页显示的图片,实现利用手势来切换页面的功能。参考代码如下:

 

void select_operate(uint16_t gesrure_value)

{

    if(gesrure_value == GES_UP) //上

    {

        if(select_value >= 2)

        {

            select_value -= 2;

        }

        dgus_show_variate_icon_location_set(SELECT_DESCRIBE_RECTANGLE, select_pos[select_value][0], select_pos[select_value][1]);

    }

    else if(gesrure_value == GES_DOWN) //

    {

        if(select_value <= 1)

        {

            select_value += 2;

        }

        dgus_show_variate_icon_location_set(SELECT_DESCRIBE_RECTANGLE, select_pos[select_value][0], select_pos[select_value][1]);

    }

    else if(gesrure_value == GES_LEFT) //左

    {

        if(select_value % 2 == 1)

        {

            select_value -= 1;

        }

        dgus_show_variate_icon_location_set(SELECT_DESCRIBE_RECTANGLE, select_pos[select_value][0], select_pos[select_value][1]);

    }

    else if(gesrure_value == GES_RIGHT) //右

    {

        if(select_value % 2 == 0)

        {

            select_value += 1;

        }

        dgus_show_variate_icon_location_set(SELECT_DESCRIBE_RECTANGLE, select_pos[select_value][0], select_pos[select_value][1]);

    }

}
